How to make RN2483 node use a fixed channel and spreading factor?

I am trying to connect an RN2483 over the pycom LoraWAN nano gateway on the TTN platform. The gateway is working fine and is connected on the TTN platform with the default settings (68610000 Mhz - DR5)

forthe RN2483 i configured it to work on a single channel. This is the commands i used:

loraSerial.println(“mac reset 868”);
delay(100);
loraSerial.println(“mac set ch status 0 off”);
delay(100);
loraSerial.println(“mac set ch status 1 off”);
delay(100);
loraSerial.println(“mac set ch status 2 off”);
delay(100);
loraSerial.println(“mac set ch freq 5 868100000”);
delay(100);
loraSerial.println(“mac set ch dcycle 5 9”);
delay(100);
loraSerial.println(“mac set ch drrange 5 0 5”);
delay(100);
loraSerial.println(“mac set ch status 5 on”);
delay(100);

loraSerial.println(“mac set devaddr xxxxxxx”);
delay(100);
loraSerial.println(“mac set nwkskey xxxxxxx”);
delay(100);
loraSerial.println(“mac set appskey xxxxxxx”);
delay(100);
loraSerial.println(“mac set adr off”);
delay(100);
loraSerial.println(“mac set ar off”);
delay(100);
loraSerial.println(“mac set pwridx 1”);
delay(100);
loraSerial.println(“mac set dr 5”);
delay(100);
loraSerial.println(“mac join abp”);
delay(100);

then i tried to send a message for example:

mac tx cnf 1 12345678

but i don’t receive anything?

I have in parallel a multitech connect to Loriot which receives the message with the correct freq & DR.

Did anyone ever connected an RN2483 over a pycom LoRaWAN nano gateway?
