Random crashes on ESP32-WROOM-32UE

[y-runwal]

Hi community!!
I am having ESP32-WROOM-32UE with external antenna and it scans BLE devices and sends them to Cloud over WiFi (4G dongle). But I am observing auto reset issues (sometimes stuck). I am using AsyncMQTT_ESP32 by Marvin Roger, Khoi Hoang.. Version 1.10.0 and Board Manager: esp32 by Expressif Systems Version 3.0.3. Can anyone suggest what might be problem? Or can anyone suggest how can I debug it? Also if need something, do let me know.

Sometime device used to work continuously for 2-3 days, sometimes it used crash at first message publish only. Whenever I used to observe ESP crash/reset, it was due to memory allocation issue I think (backtrace led me to mqtt publish function).

This issue may be related to the power supply. What are you using for power?

I'm working on the same project. Could you share which antenna cable and antenna you are using?

Hello, in my case dongle was causing issue. Its RF was interfering with my traces. I just used aluminium foil to block RF coming towards board. This helped me.
