Heltec ESP32 WiFi LoRa v2 freezes

#1

Hello everyone,

I have a project based on the Heltec ESP32 WiFi LoRa v2, the goal is to acquire some commands from our remote server and sent commands to nodes via LoRa. Nodes are designed for being powered by a battery pack charged by a solar panel.
The nodes are giving us some trouble.

The big problem is that the nodes freeze, sometime after 10 hours, and sometimes after a week, it happens at random times.

Do you have any suggestions? External reset? I don’t know what to do next.

Thank you for your help

What do you mean by freezing? Is the program stuck?

Hi, @navi thanks for the response. ESP32 freezing means that nothing is in the serial monitor and nothing is on display and it starts working only after reset. I don’t think that its program is stuck because it’s happening not for all ESP32.

Use the internal watchdog to see if this will happen.
