LoRa module - setting parameters

Hi there,

I’m playing with LoRa module but not all I’m able to set.
I flashed latest firmware to core module.
Connected with HTerm … Ok.
AT$HELP -> lists all available commands … Ok
Then:
AT$APPKEY?
returns:
$APPKEY: 2B7E151628AED2A6ABF7158809CF4F3C
I want to set new APPKEY:
AT$APPKEY=74aa4d0e7d838792c6d6366f86b8e28c
returns:
ERROR
I want to set new DEVKEY:
AT$DEVEUI=3dc4eb1e0a817060
returns:
ERROR

What I’m doing wrong?
Regards
Oskar

Hello Oskar,
try to use capital letters in HEX values.

Hello Martin,

thank you for your hint, now I’m able to set KEYs.
