Release Notes for ZentriOS-WZ-3.6

ZentriOS-WZ-3.6 has new features and fixes.

The ota command has an added option to allow automatic flash formatting if product code changes in the course of an OTA.

New options are available to avoid leaving a device disabled after an incomplete OTA. New variables, system.safemode.console_timeout, system.safemode.sleep_timeout and system.safemode.ota_auto_retry allow timing control for safemode OTA retries.

Last Updated : March, 2018

Fixes and Improvements

Topic	Description
ZAP TCP	Fixed a problem where `tcp_client_receive_handler()` could be invoked before `tcp_client_connect_handler()`.
Reboot deinit	Fixed a problem where the `zn_app_deinit()` function was not called in the event of a reboot.
Null pointer	Fixed a problem where a null pointer error in native API code resulted in unexpected behavior.
Timestamp	Fixed a problem where setting system.cmd.timestamp to `rtc` prevented the SDK communicating with the device, causing operations such as `Build/Download/Run` to fail.
NTP	Fixed a problem where enabling MDNS prevented NTP updating module time.
UART BAUD	Fixed a problem in stream mode, where changing the serial baud rate, then issuing the breakout string (e.g. `$$$`), resulted in a non-responsive state then a reboot.
DHCP IP	Fixed a problem where the device IP, issued by DHCP, was not cleared when the network BSSID was changed.
Soft AP DHCP	Fixed a problem where a client connection event was not triggered when the SoftAP DHCP server was disabled, so softap.client_list did not include a successfully connected Soft AP client with a static IP address. This issue also affected `zn_network_register_softap_event_handler()`.
