Gateway configuration

Hi,

I made gateway with R3B and DWM1001.
I set the PanID 0x1234, but It changed 0x0000 by it self.
In addition, It changed from the bridge node (active) to bridge node off.

I set the file ‘/etc/dwm1001/dwm1001.configure’
with PanID 0x1234 and UWB mode active(2).

Do you know why does it work like this?
Thanks.
