You can reset the devnonce on TTN (or even set it to be ignored). Go to the end devices section on TTN, open the end device affected, go to settings and scroll down all the way to join settings and click expand.

The devnonce is stored in the nvs partition, which is normally not erased when just flashing a firmware update. But if the board is erased completely then the last devnonce used is also erased.

I solved my issue using the UART directly from the Pins P21(TX) and P22(RX). I’ve also deduped UART 1 and use it to communicate with my peripheral.
To monitor with the REPL I’m using /dev/ttyACM0 (Ubuntu system)

Hello @Pauleera , yes the board can still be used, the documentation is available here: https://docs.pycom.io/

The Pybytes platform however is no longer online, and old Pycom products are not supported on the SG Wireless Cloud platform.
