Hi Aleksander,

on the AT interface Quectel provides their vendor-specific AT+QMBNCFG
command which has similar functionality as AT!IMPREF from Sierra Wireless.
No idea whether it is also implemented for RM520N devices as I have only
used it on RM500Q devices myself.

@Pradeep: please refer to the RM520N AT command manual or
https://forums.quectel.com/ for details.

Reinhard
