Lopy4 core panic crash while using as LoRA Nano Gateway
-
Hello everyone,
I'm currently facing a problem while using one of my Lopy4 as a LoRaWAN Nano Gateway. I'm using the latest version of the example from Pycom (see here).
After a random time, the Lopy4 is crashing with the following error :Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled.
