MKRWAN1300 change Subfrequency

Good evening.

I have a MKRWAN 1300 with a GPS Tracker programm (otaa) on it:

My Gateway, Dragino LG02, is running on 868.400000Mhz and it don't receive anything from the MKRWAN1300. I think the MKRWAN is sending on the standard frequency 868100000

Is there any option to change the subfrequency to 868400000

Any suggetions to this problem?

best regards,

EDIT: I changed the Gateway Frequency to 868100000Mhz.
