What is happening:

The BX3105 works fine for a couple of seconds, with WIFI (2.4G WPA/PSK2) connected and a bluetooth classic terminal connected. then it resets with the error code 919 / 922 (sometimes one, sometimes the other) and a error message similar to ESP boot. i did not find much about what are these errors, neither have a clue of why its resetting the RTC Watchdog (boot message).

i don’t see error code 919 in your log…  
Is problem only related to MQTT?  
How about simple TCP connection?

</div>

simple TCP connection is working fine.  
yes the problem related to MQTT.  
whenever network is not available, the MQTT was not able to send the data to the server. Then I’m executing the Wi-Fi initialization code.  
in this case am getting the **rst:0x1 (POWERON\_RESET),boot:0x13 (SPI\_FAST\_FLASH\_BOOT)** issue

How about close and delete the MQTT session when it is not able to send data?
