Automatically assign new LoRa MAC to LoPy4?

[d.alvrzx]

Hello all,

Is it possible to use the Pycom Firmware Updater to assign a new LoRa MAC to a LoPy4 device? Due to some decisions made when deploying devices to the field, I now have 2 devices with the same LoRa MAC. One of them is only used for testing, so I would like to assign a new LoRa MAC.

I know that I can do this manually (writing to /flash/sys/lpwan.mac) but then I would have to assign some arbitrary MAC. Is it possible to ask the Pycom Firmware Updater to do this?

NOTE: If i do erase_all via the CLI tool and then use the Pycom Firmware Updater to flash a new firmware, the same (old) MAC is assigned again.

Any help is appreciated!

Best,

Dan
