Zentri AMW106 Numbat

The AMW106 'Numbat 106' module is an ultra-low power Wi-Fi networking module with full regulatory certification.

The AMW136 'Numbat 136' has an additional built-in PCB antenna, and is otherwise identical to the AMW106. The AMW136 works only with the built-in antenna, and does not support antenna diversity.

For an evaluation board based on the AMW106 module, see AMW106-E03 Moray.

Example

Set UART1 baud to 2,000,000:

uart.baud 1 2000000 raw

Data

Variable: uart.data

Range: 8 - 9

Example

Set UART1 to 8 bits

uart.data 1 8

Flow

AMW106 GPIOs 0 to 4 Disabled During SDK Debugging

The Zentri AMW106 overloads the JTAG pins with the pins allocated to GPIO0, GPIO1, GPIO2, GPIO3 and GPIO4. Because the ZentriOS SDK uses JTAG for controlling the module and debugging, there is a conflict when using the ZentriOS SDK with apps requiring these GPIOs.

You can still develop a ZentrioS app that uses GPIOs 0 to 4, but you have to turn off debugging to run the app.

Build and download the app to the device in the usual way. When the app is downloaded, issue the following commands at the ZentriOS terminal:

set zap.debug.enabled 0
save
reboot

After rebooting, the app runs.

To continue developing the app using the SDK, you need to turn debugging back on:

set zap.debug.enabled 1
save
reboot

Note: GPIO0 corresponds to Button 1.
