Hello, currently im using B-L072Z-LRWAN1 send AT command to multitech gateway and server is loriot.io. And i cant get data at the server.

Firmware version B-L072Z-LRWAN1 v1.1.1

AT command:

   AT

   AT+CFM=0

   AT+NJM=0

   AT+DADDR=...

   AT+NWKSKEY=...

   AT+APPSKEY=...

   AT+JOIN

   AT+NJS=? (response = 1)

Any suggestion?

There is a problem with the sscanf() in the AT+SEND command parsing

uint8_t appport; needs to be 

uint32_t appport;

See also the rest of that thread for some foundation in the issue.

Thank for fast answer Clive One

I will try it tomorrow, but my config above is correct ?

I see when i run AT+JOIN the DADDR, 

NWKSKEY, APPSKEY is back to default. Is there something wrong?

I'm doing mostly point-to-point communication, I don't have a Gateway to tinker with.
