WiConnect commands

This page provides a list of WiConnect commands with a full description of how to use each command.

Nav Tips for Humans

WiConnect command mode is friendly for humans too. Use the following tips and you'll be an expert WiConnect terminal jockey in no time flat!

Shortcuts

A shortcut is assigned to each command. Common sense dictates the rules for shortcuts. Commands that are already short do not need a shortcut other than their name, shortcuts for longer commands sometimes take the first three letters of the command name, and other times take the first letter of the name plus several other letters contained in the name. Shortcuts are no longer than six characters and are easy to guess, the ultimate reference however is command help and the documentation on this page.

Documentation Format

Many of the WiConnect responses shown in the examples on this page were captured with system.print_level = all, and system.cmd.header_enabled = true. These settings are provided to make it easy for a host microcontroller to parse responses by examining response headers. Information about machine parsing is available in Serial Interface, MCU Config.

Documentation for each command is provided in the format shown below.

command

Abbreviation

cmd

Description

Description of Commands

adc_take_sample

Abbreviation

adc

Description

Take an analog sample of a pin using an onboard Analog-Digital Converter.

To set the ADC reference voltage, see system.adc.vref.

Syntax

> adc_take_sample <gpio#> [<gain>] [-v]|[-l]/[<LUT Filename.csv>]

• <gain> - optional, defaults to 1 if not specified. The valid values for the adc gain are 1, 2, 4.
• <-v> - optional, return ADC value as a voltage in mV. Do NOT use with the LUT parameter, as subsequent arguments are ignored.
• <-l> - (lower-case L) optional, return ADC value from cached LUT. Requires a prior read of the LUT from file.
• <LUT Filename.csv> - optional, filename of Lookup Table (LUT) to use for converting ADC values. See Peripherals, ADC Lookup Tables for details. Note that if using <LUT Filename.csv> argument:
  • the <gain> argument is required to establish the argument position
  • no options should be used.

Note:

• The ADC LUT is cached on first use. To read and cache a different LUT from file, a reboot is required.
• Thermistors may vary. For precise temperature readings, create a LUT calibrated for your thermistor. See Temperature versus ADC value for a sample LUT.

The ADC value can be read in three formats:

• to read a numeric hex value, use no option.
• to read in mV, use the -v option.
• to use the LUT from cache, use the -l option. Requires a prior read of LUT from file, as described above.

Example

> adc 1 1
R000007
0x805
> adc 7 1 therm_celsius_lut.csv

file_delete

Abbreviation

fde

Description

Delete a file from the file system.

Syntax

> file_delete <filename> | <memory>-<handle> where

• <filename> is the name of the file
• <memory>-<handle> can be used to distinguish between files with the same name:
  • <memory> is the memory type, which may be one of the following:
    • i - internal memory
    • e - extended memory
    • b - bulk memory
  • <handle> is the file handle on the memory. This appears under the Hnd column of the file listing

Note: <memory>-<handle> overrides <filename> - for example, if there exist both a file in extended flash with file handle 234, and a file named e-234, then the command file_delete e-234 deletes the file with memory-handle e-234, rather than the file named e-234.

Example

> fde myfile.txt
L000014
File deleted
R000009
Success

Example

To delete the file with handle 234 on extended flash:

> file_delete e-234
L000014
File deleted
R000009
Success

file_open

Abbreviation

fop

Description

Open a file and return a file stream handle if successful. Once open, the file contents may be read with the stream_read command.

Syntax

> file_open <filename> | <memory>-<handle> where

• <filename> is the name of the file
• <memory>-<handle> can be used to distinguish between files with the same name:
  • <memory> is the memory type, which may be one of the following:
    • i - internal memory
    • e - extended memory
    • b - bulk memory
  • <handle> is the file handle on the memory. This appears under the Hnd column of the file listing

Note: <memory>-<handle> overrides <filename> - for example, if there exist both a file in extended flash with file handle 234, and a file named e-234, then the command file_open e-234 opens the file with memory-handle e-234, rather than the file named e-234.

Example

> fop myfile.txt
R000003
0

Example

To open the file with handle 234 on extended flash:

> file_open e-234
R000003
0

file_stat

Abbreviation

fst

Description

Display file statistics for the specified file.

You can supply the filename, or the file handle in <memory type>-<handle> format.

Statistics are displayed in a comma separated list, in the order:

size,CRC,long version,storage type,file type,flags

The ls -v (verbose file listing) command displays all of these properties except the CRC.

Syntax

> file_stat <filename>/<memory type>-<handle> where:

• <memory type> is the letter at the start of the Type column in the ls -l listing of a file:
  • e:extended
  • i:internal
  • b:bulk.
    See File System, File Types.
• <handle> is the file ID number listed in the Hnd column in the ls -l listing of a file.
  The handle must be prefixed by the memory type followed by a dash, e.g e- for extended flash.

Example

> file_stat geotrust_ca.pem
1236,6E5A,2.4.1.1,e,03,01

Description

Activate the device with goHACK.me. A valid goHACK.me username and password must be provided. If a capabilities filename is provided, the ghm.capabilities variable is updated with the specified filename. See goHACK.me Device Capabilities.

Need a goHACK.me account? Signup at goHack.me and then use ghm_activate to activate your device. See goHACK.me, Basic Account for details of restrictions.

Note: If ghm.solo.enabled is set, the device reboots and automatically connects to goHACK.me after activation completes successfully.

Syntax

> ghm_activate <username> <password> [capabilities filename]

Example

> get ghm.capabilities
ghm_capabilities.json
> ghm_activate your-email@address.com ******** mycaps.json
Request POST /api/activate/login

ghm_capabilities

Abbreviation

gca

Description

The ghm_capabilities command enables users to download and manipulate goHACK.me device capabilities files. Options include the ability to list example capabilities files on the goHACK.me server, download a specific capabilities file and setup the device to use it, or independently configure which capabilities file to use when the device activates with goHACK.me.

Note! After device activation, the capabilities file is read only. To modify or delete the file, first deactivate the device using ghm_deactivate.

Syntax

Listing Capabilities

> ghm_capabilities <list>

where:

• returns a list of example capabilities files for use with the device

Downloading Capabilities > ghm_capabilities download [<filename / URL> [-s] [-d] [<version>] where:

• <filename> - The name of the capabilities file to download. If no filename is specified, download the default caps file, typically ghm_capabilities.json, and set it for use with goHACK.me
  Note:
  • Example caps files downloaded from ACKme overwrite existing files with the same name.
  • Do not add a JSON extension to the filename
• <URL> - URL specifying the network location of the file. Local caps files with an identical name to a downloaded caps file will not be overwritten. In this case, the command fails. Delete the version of the file manually first.
• [-s] - Download a setup script that works with the capabilities, then run the script to setup the device to run 'solo' in a standalone mode (external host not needed!).
• [-d] - Download the file only, do not set the file for use.
• [version] - Provide a version number for the file.

All parameters are optional. If no parameters are provided, the default capabilities file for the device is downloaded and configured for use with goHACK.me.
Note:

• Device activation is NOT required to use this command
• The capabilities filename on the server is used as the filename on the local file system. If the file already exists on the filesystem, the command fails.

Setup & Querying Capabilities > ghm_capabilities <get/set> where:

• <get> returns the filename of the capabilities used with goHACK.me. The ghm.capabilities variable may also be used to return the capabilities filename.
• <set> sets the filename of the capabilities to be used with goHACK.me

ghm_message

Abbreviation

gme

Description

goHACK.me provides the ability for devices to get messages from a message box called to-device and post messages to a message box called from-device. The ghm_message API is used to manipulate messages. The primary message options are list, get, post and delete.

Syntax

Listing Messages

> ghm_message <list> [<-t time> / <-c count>]

where:

• < -t time> - gets all messages since the specified time
• < -c count> - gets 'count' messages, latest first

Getting Messages

> ghm_message <get> [<list_index / msg_id>]  [<all> / <body>]

where:

• <list_index / msg_id> is optional, the latest message is returned if omitted
• <list_index> is the message index returned by ghm_message <list>
• <msg_id> is the ID of a specific message
• <all / body> is optional, only the message text is returned if omitted
• <all> returns the entire message including the message header
• <body> returns the JSON formatted message body

If successful, ghm_message returns a stream handle, the message may then be read using the stream_read command.

Posting Messages > ghm_message <post>

If successful, the ghm_message returns a stream handle. The message may then be written using the stream_write command. To complete and send the message, use the stream_close command.

Deleting Messages > ghm_message <delete> <index / msg ID> where:

• <index / msg ID> is either the message index returned by ghm_message <list> or the ID of a message

http_download

Abbreviation

hdo

Description

Download one or more files from a remote HTTP server and save to the extended or bulk flash.

Timeout is determined by tcp.client.connect_timeout.

Note: The remote HTTP server must return the Content-length header in the HTTP response. The file system must have the size of the file before creating it.

See Networking and Security, TLS Errors for details of the error response to TLS failure.

Syntax

Download a Single File

> http_download [-i <wlan/softap>] [-m <json_size>] [-d] [-[e][u]] [-c <CRC>] <url>
  [<flash_file_name> [<version> [<type> [<cert_filename>  ] ] ] ]

where parameters are as follows:

• hex format: upper or lower case, with or without leading 0x, e.g. 0xFE, fe, 0xe1c8

Downloading Multiple Files > http_download -m <json_size>

Immediately after issuing this command, send <json size> bytes of a JSON formatted manifest file. An example of the manifest file is as follows:

{
   "path"  : "https://myserver.com/path/to/my/files/",
   "cert"  : "mycert.pem",
   "files" : [
                {
                    "remote"  : "name_of_remote_file.html",
                    "local"   : "name_of_flash_file.html",
                    "version" : "1.0.0",
                    "type"    : 150,
                    "flags"   : "eu",
                    "crc"     : 23423
                },
                { ... }
              ]
}

Notes:

• Only the "remote" parameter is mandatory. The other parameters are optional.
• In the manifest, the file type and crc are expressed in decimal, not hex, unlike in the -c parameter.
• The file type 150 (hex 0x96) is a custom user type.

String Replacement

WiConnect allows string replacement in the URL of the file for download, using a C-like or pythonesque syntax.

If the url contains %s, then the supplied filename is substituted for %s.

Example: hdo 192.168.1.110:50007?id=%s&action=download my_file.txt generates the URL: http://192.168.1.110:50007?id=my_file.txt&action=download and creates the file: my_file.txt in the module file system.

String replacement is also available in the manifest. For example:

{
   "path" : "http://myserver.com?file=%s&user=name&pass=1234",
   "cert" : "mycert.pem",
   "files" : [
                {
                    "remote" : "my_file1.txt",
                },
                {
                    "remote" : "my_file2.txt",
                },
              ]
}

generates the following URLs for download:

http://myserver.com?file=my_file1.txt&user=name&pass=1234
http://myserver.com?file=my_file2.txt&user=name&pass=1234

Example

Save page at example.com to file test.html:

> hdo http://example.com test.html
Downloading: test.html to flash file system
Request GET /

I

i2c_master_config

Abbreviation

i2cmc

Description

Configure an I2C slave peripheral such as an accelerometer, humidity sensor, light sensor, etc.

Notes:

• This is a run-time only command. The settings are reset upon a reboot/power-cycle
• This command must be issued at least once before issuing the i2c_master_open command
• Issuing this command multiple times for the same <slave address> updates its settings
• Issue this command for each connected slave
• To display the configuration for a previously configured slave, issue this command with only the <slave hex address> argument
• Summary of unsupported features:
  • Clock stretching
  • 10-bit addresses

Syntax

> i2c_master_config <slave hex address> <clock rate> [<retries> [<config bitmask>]]

where:

• <slave hex address> - the 7bit I2C slave address in hex
• <clock rate> - I2C clock rate, The clock rate may be any value. Several special values are also supported:
  • low - low speed: 10kHz
  • standard - standard speed: 100kHz
  • high - high speed: 400kHz
• <retries> - optional, if specified then a register read/write will be attempted <retries> times before returning the failure code. This settings is only used if <register address> is supplied with a read/write command
• <config bitmask> - slave configuration. Hex string bitmask. See below.

<config bitmask> is a bitmask specifying the various flags for the I2C slave. The bits have the following meanings:

Example

> i2c_master_config 0x19 standard 0 0x01
Success
> i2c_master_config 0x19
! Addr Clock  Flags Retries
# 0x19 100000 0x01  0

i2c_master_open

Abbreviation

i2cmo

Description

Open an I2C stream for read/write. Optionally specify the size of the read buffer.

The stream can then be used with the stream commands. Stream command behavior is modified for i2c as follows:

Notes:

• This is a run-time only command. The settings are reset upon a reboot/power-cycle
• This command must be issued at least once before issuing the i2c_master_open command
• Issuing this command multiple times for the same <slave hex address> updates its settings
• Issue this command for each connected slave
• To see the configuration for a previously configured slave, issue this command with only the <slave hex address> argument

Syntax

> i2c_master_open [<rx buffer>]

where:

• <rx_buffer> is the maximum number of bytes that may be read using the read command.
  Default: 128 bytes.

I2C Write Command

Once an I2C stream is opened, the write command is used to write data to an I2C slave. The write command has additional arguments to specify the register address and slave address to write. write <handle> <write size> [<flags> [<register address> [<slave address>]]] where:

• <flags> - hex bitmask:
  • 0x01 = continued write: if this bit is set then no stop condition will be sent after the write. This allows for issuing the write command multiple times within the same I2C frame.
• <register address> - if specified then <register address> is first written to the bus, followed by <write size> bytes of data.
• <slave address> - if specified then this slave address along with its corresponding settings are used else the last specified slave address is used.

Notes:

• Only 8bit register addresses are supported for
• Only 7bit slave addresses are supported for

I2C Read Command

Once an I2C stream is opened, the read command is used to read data from an I2C slave. The read command has additional arguments to specify the register address and slave address to read.

read <handle> <read size> [<flags> [<register address> [<slave address>]]] where:

• <flags> - hex bitmask: Reserved for future expansion, leave as 0x00
• <register address> - if specified then <register address> is first written to the bus followed by reading <read size> bytes of data.
• <slave address> - if specified then this slave address along with its corresponding settings are used else the last specified slave address is used.

Notes:

• Only 8bit register addresses are supported for
• Only 7bit slave addresses are supported for

Example

The following shows how to read/write the LIS3DH Accelerometer via the I2C bus. The LIS3DH Accelerometer comes with the Seabass and Snapper evaluation boards).

Quick notes about the LIS3DH

Slave address = 0x19

If the MSb of a register address is set then the register address automatically increments for subsequent read/writes. This auto-increment is a feature of the LIS3DH, not of WiConnect.

>i2c_master_config 0x19 standard 0 0x01

Configure I2C slave address: 0x19,
  'standard' clock, no retries, and hexify flag
Open an I2C stream


Read register 0x0F (aka Who Am I register)
  should return 0x33
Write CTRL_REG 1-4 (0x20 - 0x23),
  use LIS3DH's register auto-increment feature
  by setting MSb of register address.
  Use 'continued write' flag
Write CTRL_REG2 (0x21)
  (recall we're using 'continued write' flag
  and chip's register auto-increment feature)
Write CTRL_REG3 (0x22)


Write CTRL_REG4 (0x23). This is the last write
  so don't use the 'continued write' flag

Read back registers 0x20-0x23
  Set MSb of register address so the register address
  is automatically incremented

L

ls

Abbreviation

ls

Description

Return a list of available files located in internal, extended and bulk flash.

Use the -v (or equivalent -l) option for full details.

The -m, -b and -c support paging and limiting the output, for use when there are many files.

Syntax

> ls [-v/-l] [-m <i|e|b>] [-b <base sector>] [-c <max file count>] where:

• -m the memory type to search, this is a concatenation of one or more of the following types:
  • i - internal
  • e - extended
  • b - bulk
• -b the base file sector at which to begin searching for files on the given memories. When the -b option is used, alphabetical sorting is turned off.
• -c the max file count to return

network_up

Abbreviation

nup

Description

Start the process to bring up a network interface. The -s option prompts the user to select from a list of available APs. The -i option overrides the default network interface specified by network.default_interface.

NOTE! Every command that needs access to the network will automatically bring up the network interface. The network_up command is non-blocking (except when the -s option is used) and provided for convenience only.

Syntax

> network_up [<-s> / <-i [wlan]/[softap]>]

Example

> network_up -s

network_verify

Abbreviation

nve

Description

Verify the module can connect to a Wi-Fi network with specific network credentials. This command provides a fast way test the network credentials entered by a user are valid when web setup with softAP is operational, see Configuration & Setup, Web Setup. At present, only the Wi-Fi credentials are verified. No attempt is made to verify whether the module can obtain an IP address using DHCP.

The network verify command can also be used to quickly test network credentials at any time, however if the module is already connected to a network on the wlan client interface, it will be automatically disconnected from that network first.

If the verification attempt is unsuccessful, the command responds with Timeout. Verification may be unsuccessful if either the credentials provided are incorrect, or the verification attempt takes longer than 1 second.

Notes

• The wlan_scan -v command returns detailed information (including the BSSID, AP channel and security type) of Wi-Fi APs in range. A relevant subset of this information may be passed to the network_verify command.
• For WPA/WPA2, the PSK/PMK is calculated by applying the PBKDF2 key derivation function to the WPA/WPA2 passphrase using the SSID as the salt and 4096 iterations of HMAC-SHA1, see here for additional information.

Syntax

> network_verify wifi <ssid> <bssid> <ap channel> [<security> <psk>] where:

• <ssid> - the name of the Wi-Fi network
• <bssid> - the MAC address of the Wi-Fi Access Point (colons in the MAC are optional)
• <ap channel> - the radio channel of the AP
• <security> - an enumeration of the security type used by the AP:
  • 1 = WEP
  • 2 = WPA-AES
  • 3 = WPA-TKIP
  • 4 = WPA2-AES
  • 5 = WPA2-Mixed
  • 6 = WPA2-TKIP
• <psk> - 64 hex character pre-shared key (aka PMK) for WPA/WPA2 or WEP key

Example (Open Security)

> network_verify wifi mynetwork 4C55CC102F1A 1

ota

Abbreviation

ota

Description

Initiate a secure over-the-air update using the ota server specified by the variables ota.host, ota.port. The secure OTA protocol uses industry standard TLS/HTTPS security with both client-side and server-side certificate verification.

As an additional measure of security, the server authenticates each device using the universally unique system.uuid embedded inside the hardware of each device.

Optionally force an update with the -f option. Download a specific firmware bundle version with the -b option.

To claim a module and possibly activate the module to receive a custom product (firmware and files), use the -a option. Follow the ota -a command with the ota -f command to update the module to the activated product. See DMS Glossary for definitions of claim and activate.

The ota -a option can be used to update from WiConnect to ZentriOS. See ZentriOS, Updating from WiConnect to ZentriOS, Updating to a Specific Product.

All modules are activated and licensed for standard WiConnect firmware.

If you have firmware customised by Zentri for your application, or you would like Zentri to manage your host firmware or host application files on our secure servers, please contact Zentri.

To maintain a saved configuration through an OTA upgrade, save the configuration as default_config.csv. See save.

See Networking and Security, TLS Errors for details of the error response to TLS failure.

Syntax

> ota [-f] [-b <bundle name>] [-u <user file>] [-a [<product ID>:]<username> <password>]/[-a [<product ID> <activation token>]

• -f : force update
• -b : download a specified bundle, for example a previous version.
• -u : download a user file. User files must be stored on the Zentri Device Management Server (DMS).
• -a : to claim and activate to a product, use one of the following:
  • -a <product ID>:<DMS username> <DMS password> - Specify the product ID, followed by a colon, then your DMS username and password. If no <product ID>is specified, the ota -a <DMS username> <DMS password command claims the module, but does not activate it to a specific product.
  • -a <product ID> <activation token> - for details on using an activation token, see DMS, activation token

save

Abbreviation

save

Description

Save all WiConnect variables to non-volatile flash memory.

If a file name is supplied, the saved configuration can be restored with the load command.

Save as default_config.csv to create a default settings file. If a file of this name is found, WiConnect loads the configuration in default_config.csv after a successful OTA or if the factory reset GPIO is asserted for more than 5 seconds but less than 10 seconds. See Upgrade and Recovery, Factory Reset.

Note: During the save operation, interrupts are disabled. In particular, the UART rx interrupt may not be serviced during save. To ensure the save operation is completed, wait for the save command response before issuing further commands via the UART.

set

Abbreviation

set

Description

Set the value of a WiConnect variable.

Syntax

> set <variable> <args>

Note: The set command displays the Too many args error only if the number of space-separated arguments exceeds the maximum for all variables (5). However the number of arguments for the set command depends on the variable being set, and the form in which the variable is specified: abbreviations for variables vary from one to three arguments in length, and variable settings may require one or two arguments. If you specify too many arguments when setting a specific variable, surplus arguments are ignored. Refer to the variable documentation for the number of arguments for a specific variable.

Example

> set wlan.ssid "My Home Network"
R000008
Set OK

setup

Abbreviation

setup

Description

The setup command simplifies the process of connecting an ACKme module to a Wi-Fi network. It can also be used to automate device configuration and setup.

The setup command allows for set up from the WiConnect terminal, using a command script, or via a web browser.

See Configuration and Setup, Configuration Script and Configuration and Setup, Setup with a Web Browser.

The setup command can be run automatically on boot or in response to asserting a GPIO. See Configuration and Setup, Automatically Executing a Script.

spi_master_config

Abbreviation

spimc

Description

Configure a SPI slave peripheral such as an accelerometer, humidity sensor, light sensor, etc.

Note: This is a run-time only command. The settings are reset upon a reboot/power-cycle.

This should be issued before using the spi_master_open command to open a SPI stream.

To display the SPI configuration for a previously configured slave-select GPIO, issue the command with only the <slave-select gpio #> argument.

Syntax

> spi_master_config <slave-select gpio #> <config bitmask> [<clock rate>]

where:

• <slave-select gpio #> - the GPIO to use as a slave-select signal
• <config bitmask> - slave configuration. Hex string bitmask. See below.
• <clock rate> - optional, the SPI master clock rate, default is 20MHz if not specified

<config bitmask> is a bitmask specifying the various flags for the SPI slave. The bits have the following meanings:

Example

> spi_master_config 9 0C
Success
> spimc 9
!  # Flags Clock
#  9 0x0C  2000000
> get gp u
!  # Description
...
#  9 SPI0 CS
...

spi_master_open

Abbreviation

spimo

Description

Open a SPI master stream for read/write. Optionally specify an Rx buffer size.

The stream can then be used with the stream commands. Stream command behavior is modified for SPI as follows:

Before using spi_master_open command, the <slave-select gpio #> must have been previously configured using the spi_master_config command. If no argument is supplied, the most recently specified <slave-select gpio #> is used.

Note: The caller must ensure that the contents of <rx buffer> is cleared before switching <slave-select gpio #>, as data is always read from <rx buffer> before reading from the SPI bus.

Syntax

> spi_master_open [<rx buffer>]

where:

• <rx buffer> - optionally specify how many bytes of data the stream_write command buffers before the stream_read command must be called (the stream_write command fails if the <rx buffer> is full).
  Default: 128 bytes.

Example

> spi_master_open 256
0
> write 0 10 2
...
> read 0 10

open the SPI master stream with <rx buffer> size of 256 bytes
(return stream handle 0)
write 10 bytes to slave 2 as the slave select to SPI bus
(this simultaneously reads 10 bytes)
read 10 bytes from buffer

stream_close

Abbreviation

close

Description

Close an open network or file stream specified by [handle], or alternatively close all open streams.

Syntax

> stream_close <[handle]/[all]>

Example

> close all
[2014-04-02 | 13:32:04: Disconnected: 0]
[2014-04-02 | 13:32:04: Disconnected: 1]

stream_list

Abbreviation

list

Description

Return a list of open streams.

Syntax

> stream_list

Example

> list
!# Type  Info
#0 TCPC  google.com:80 (32288)
#1 HTTP  ack.me:80 (37289)

stream_poll

Abbreviation

poll

Description

Poll a stream to check if data is available. Returns 0 if open with no data to read, 1 if data is available and 2 if the stream has been closed remotely. Use the all option to return the status of all open streams. To avoid polling, use a GPIO (may be assigned when the stream is opened) as an interrupt line to the host.

Syntax

> stream_poll [all] <handle> [-c] where:

• -c - response also includes count of bytes available If -c is included in the command, the response format is as follows:

Poll specific connection

> poll 0 -c
<status>,<bytes available>

Poll all connections

> poll all -c
<handle>,<status>,<bytes available>|<handle>,<status>,<bytes available>|...

where:

• <handle> - stream handle
• <status> -
  • 0 - no data available
  • 1 - data available
  • 2 - remote closed connection
• <bytes available> - the total number of bytes buffered

Example

> poll 0
1
> read 0 100
hello!
> poll 0
0
> poll all
0,0|2,1|3,1

stream_read

Abbreviation

read

Description

Read up to <size> bytes from a network or file stream. Returns data immediately (if available), does not wait to receive data. For network streams, WiConnect may buffer up to seven packets with each packet containing up to 1460 (MTU) data bytes. To avoid receiving data fragmented across packets, <size> should be set to 1460 bytes. To check for data, use the stream_poll command or the GPIO (assigned when the stream was opened) as an interrupt line to the host. For file streams, the file is automatically closed if the end of file is reached.

Read times out after the period specified in bus_command_read_timeout.

Syntax

> stream_read <handle> <size>

Example

> read 0 200

stream_write

Abbreviation

write

Description

Write data to a network or file stream. As described in Serial Interface, Command Protocol, the command must be terminated by \r\n.

If no option is specified, WiConnect waits for <size> number of data bytes then immediately sends the data to the stream before returning a response.

If the -f (flush) option is specified, then the written data is buffered to the maximum packet size before being automatically flushed to the remote side. The -f option can be used for the following stream types:

• TCP client/server
• TLS client/server
• Websocket client/server

For TCP and TLS streams, the maximum packet size is an MTU (1460 bytes).

For Websocket client/server streams, data is not locally buffered, however 'continuation' frames are used. When the -f option is specified, each written data chunk is sent as a continuation frame. If -f is not specified, then the 'final frame' flag is set.

Write times out after the period specified in bus.command.write_timeout.

Syntax

> stream_write <handle> <size> [-f] where:

• -f : optional. Buffer to maximum packet size before flushing, as described above.

Example

> write 3 10
Success

T

udp_server

Abbreviation

udps

Description

Start and stop the UDP server.
When the UDP server is started the read and write sub-commands are available.
When the UDP server is started, it is assigned a stream handle, indicated in the WiConnect response by Opened: <stream>. This allows for the equivalent stream 'read' and 'write' commands.
The read command is functionally the same as: udps read.
The write command is functionally the same as udps write without the <address> and <port> options.

Syntax

> udp_server <start/stop> [port] Start and stop the UDP server. Port may be optionally specified. If no port is specified the default is udp.server.port.
> udp_server read [-q] [<byte_count>] where :

• -q - optionally prepend the client's IP address and port before the data bytes, in a comma-separated list: ip,port,data

• <byte_count> - The number of bytes to read. Note that only a single packet's worth of data is returned
  i.e. data returned = MIN(<byte count>, len(packet))

  > udp_server write <byte_count> [<address> <port>] where :

• <byte_count> - the number of data bytes to write
• <address>, <port> - optional, the remote client's address and port. If omitted, write to last client whose data has been read.

websocket_client

Abbreviation

webc

Description

Opens a client websocket stream to a remote server. Returns a stream handle which may then be used with the read/write/poll/close commands.

The Websocket client connection can be controlled by a GPIO. See the ioconn.protocol web.

Data availability can be determined by an OOB GPIO event. See the system.oob.gpio event websocket.client.data_gpio.

Websocket Message Format

Websocket data passed between WiConnect and remote server is sent in messages or frames. These messages start with a header. One element of the header is the message type. WiConnect supports the 'text' and 'binary' message types. Note that Wiconnect treats all data as binary. The message type is only used by the remote side (for instance so a javascript library can convert the data to the correct format).

For more information see: https://developer.mozilla.org/en-US/docs/WebSockets/Writing_WebSocket_servers

Syntax

> websocket_client [-i <wlan/softap>] [-g <gpio> ] [-f <txt/bin>] <url> [<cert filename>] where:

• -i - specify interface. MUST come first. If omitted uses network.default_interface.
• -g - specify data GPIO for given stream. This gpio is asserted HIGH when the stream has data to be read
• -f - specify the websocket frame or message format. Default is txt if option not specified:
  • txt - text data (or ASCII)
  • bin - binary
• url - the remote server URL. This follows the same conventions as the http_get/http_post commands. Port default depends on URL scheme:
  • URL scheme ws: port defaults to 80
  • URL scheme wss: port defaults to 443
• cert filename - name of TLS certificate filename. If the scheme is https or wss or the cert is specified, then the websocket connection uses TLS. If the scheme is https or wss and no cert is specified, then the variable network.ca_cert is used.

Example

> websocket_client ws://mywsserver.com

wlan_scan

Abbreviation

scan

Description

Initiate a Wi-Fi scan and return results; optionally specify a channel and AP SSID to scan for. For verbose scans, -v must be the first argument. Information returned by scan results is described in the following table.

Verbose scans return all columns of data. Non-verbose scans return only columns:# Ch RSSI MAC (BSSID) Network (SSID)

Syntax

> wlan_scan [-v] [<channel list/mask/all> [ssid]] where:

• -v: verbose scan - must be first argument
• <channel list/mask/all>:
  • list: a comma-separated list of channels, e.g. scan 1,5,6
  • mask: a hex bitmask of channels. Must be preceded by 0x, e.g. scan -v 0x143
  • all: all channels, e.g. scan -v all

Example

> scan -v
