Release Notes for ZentriOS-WZ-3.1
ZentriOS-WZ-3.1 provides fixes and improvements to version 3.0.
Security features include new user encryption options, and automatic encryption of certificates and configuration files. See new system.security_key encryption options for file_create, file_open, http_download, and http_upload commands,
User Encrypted file flag and new automatic encryption for the save command. See also File System, Encrypting Files for use by ZentriOS.
You can also set a TLS certificate when using tcp.client.auto_start. See tcp.client.tls_enabled.
New features for stream writes and reads allows buffer sizes to be checked before network stream read/write operations are attempted. See the bus.command.write_check_enabled variable, the stream_write and stream_poll commands, and Serial Interface, Response Format, Bounds error.
A new OOB GPIO event allows checking for HTTP data ready, using a new option with the http_get and http_post commands. See system.oob.gpio.
A GPIO can be configured as an auxiliary factory reset GPIO. See system.factory_reset.aux_gpio and system.factory_reset.aux_level variables.
The log bus can be used as an auxiliary command console. See system.cmd.aux_bus.
You can determine Soft AP RSSI with softap_get_rssi and softap.rssi_average.
Other improvements allow:
- checking if an update is available for OTA without downloading - see ota
- checking the result of an OTA - see dms.ota_result
- provide an initial value when setting GPIO direction - see gpio_dir
- WebSocket keepalive with a WebSocket ping frame - see stream_write
- arbitrary length URLs for http_get
- Setting variables unaffected by factory reset - see system.variable_lock
