lorawan-nano-gateway crashes after some time #117
Description
Hello guys
I have a LoPy4 v1.20.2.rc6 with Expansion board expansion31_0.0.11
Tried to load the example project "lorawan-nano-gateway"
After couple of hours (between 1 and 8) the LoPy crashes with following (decoded) stacktrace:
Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled.
PC: 0x4010466c: mp_obj_str_binary_op at ../py/objstr.c line 1500

Tried to use different WLANs.
I also tried to completely reset the LoPy4 like described here:

Does anyone have the same problem?
Any ideas what to try?
Appreciate your help.
