OpenBK7231T_App Stability problems on BL602 (LF686C20) using MQTT

Describe the bug After sending a lot of MQTT messages, the device randomly disconnects from the WIFI and does not reconnect automatically. Switching it on again helps, but the instability persists.

Firmware:

Version 1.17.463
Device Magic Home RGBW 12-24v 5-pin LED Strip Controller
Chip/model: LF686C20 details flashed as BT602
Device config

"flags": "537134080",
"pins": {
    "3": "PWM;0",
    "4": "PWM;1",
    "20": "PWM;3",
    "21": "PWM;2"
  }

To Reproduce Steps to reproduce the behavior:

switch on the device
send a lot of MQTT messages from node red
wait until the device has disappeared from WIFI.

The device then does not respond for some time. Sometimes it re-establishes the connection to the mqtt server because an mqtt timeout triggers an action in the device. Without having opened the web interface of the device (after a restart), the device closes the WIFI connection and remains dead.

What can I do to further analyse the behaviour of the device? Does it make sense to log the device via the serial interface?

Crashlog

I logged the output now via serial connection. I will try again and see if it crashes at the same point every time.

We've seen something similiar on BK7231. It was fixed by @valeklubomir with LWIP update. Maybe we need to port changes to BL602... https://github.com/openshwprojects/OpenBK7231T/pull/11/files

I would higly appreciate a similar fix. It would make this fantastic project much more usable.

I would also welcome this fix very much. I hope you can implement it soon :D

We have recently added watchdog for BL602 so it should help mitigate potential problems before a final solution is ready.
