i tried a lot of things.
i have the gateway profile on ABP
PROGMEM u1_t NWKSKEY
PROGMEM u1_t APPSKEY
i put the data as MSB and as LSB i even tried to put the network session key in APPSKEY and the application session key in NWKSKEY.
so i tried a lot of settings but i always get the error: device-session does not exists or fcnt or mic
Who knows to tackle this ??
