I successfully joined TTN Stack V3 using OTAA. But I noticed that I need to rejoin after every time I repower the module. I am using TPL5110 timer to switch ON/OFF the whole system periodically for many reasons. Is there a way to force the module to reuse the previously obtained provisioning keys (Device address, NwkSKey, and AppSKey) which I believe are saved in the EEPROM? It is annoying to rejoin every time I power ON the module.
Hitting the same issue this side. When using the LoRa-E5 as a radio module, one would expect to switch it off when it is not in use to save battery power.
I did this experiment:
- Power up module
- Config keys, OTAA, EU868
- Send message
- remove power
- Power back on

I think it is a thing that need to be fixed.
