7431 Firmware Reset

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? :slight_smile:
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

Hi. Please find the latest firmware for RAK7431 here. It should flash normally with the RAK DFU tool.
