Hi everybody,
I'm writing because I'd like to check if I understand the functionality of the AT command AT%XBANDLOCK correctly.
The first part of the question should be based on whether I understood the role of the permanent mask correctly. If I set the bit to one in the permanent mask, does that mean that the given band is blocked?
Nordic nrf9151-DK allow operate with bands: B1-B5, B8, B12, B13, B17-B20, B25, B26, B28, B65, B66 and B85.
If I wanna lock band 6, I will do:
AT+CFUN=0
OK
AT%XBANDLOCK=1,"100000"
OK
If I wanna lock band 10, I will do:
AT+CFUN=0 OK AT%XBANDLOCK=1,"1000000000" OK
Both bands are not supported on nrf9151. But it is correct way of using of permanent mask? Permanent mask counts will all bands of LTE or only with supported LTE bands?
My question basically asks if bandlock applies to all LTE bands regardless of whether the modem supports them (which would mean that blocking and unblocking unsupported bands would have no effect), or if it only applies to supported bands.
For and example, if I use:
AT+CFUN=0 OK AT%XBANDLOCK=1,"100000" OK
Am I locking 6th band or 6th supported band (so band 8, cause nrf9151 alllow to operate B1, B2, B3, B4, B5 and B8 and B8 is sixth lower band)?
I hope I asked my question correctly and you understand me.
Best Regards
