I believe I have deleted the firmware on the 7431. Is there anywhere I can reset this device?
I ended up getting a 4200 firmware to take… but this appears to have lost the serial features…
Hi @thepeachfarmer
How you manage to delete it? 
How you flash RAK4200 firmware? Through the board USB or with USB to TTL converter to the module?
I wasn’t getting any at command responses. So I tried upgrading the firmware. I did this upgrade process several times with different firmware’s. I wasn’t really sure which one to use.
Anyway. I just need to know how to start this 7431 back from scratch
Through USB module is where I was
