Lora GPS hat Raspberry

Hello, I have Raspberry Pi 3A+ and LoRa Dragino module, after installing the program and reworking the entire manual, the Gateway ID is : 00:00:00:ff:ff:00:00:00. What is wrong?

I found a topic but it does not exist now.

EDIT : I found a solution:
“You have to change the network interface from “eth0” to (I guess) “wlan0” in your source and recompile.”
