Set command

The command stores to NVM configurations that are set with the following commands:

• %XBANDLOCK
• %XEMPR
• %XCOEX0
• %XMAGPIO
• %XMIPIRFFEDEV
• %XMIPIRFFECTRL
• %XANTCFG
• %XCOEX2
• %XRFTEST (AFC)
• %TXSELFCAL

Syntax:

%XFSSYNC[=<mode>[,<rat>]]

+CME ERROR code

518 – Not allowed in active state.

The set command parameters and their defined values are the following:

<mode>

0 – Store configurations to NVM.

1 – Store configurations to NVM and set %XBANDLOCK operation 3, %XRFTEST (AFC measurement and set %XRFTEST) operation 4, and %TXSELFCAL permanently as read only.nRF9131

%XFSSYNC=1 fails if AFC calibration (%XRFTEST) and TX self-calibration (%TXSELFCAL) have not been executed.

CAUTION:

This is a one-time programmable command for %XBANDLOCK operation 3, %XRFTEST (AFC measurement and set %XRFTEST) operation 4, and %TXSELFCAL that cannot be re-executed or reversed.

If the parameter is not given, <mode> value 0 is used.

<rat>

Bit mask for selecting device RAT.

1 – LTE-M and Narrowband Internet of Things (NB-IoT).

2 – DECT NR+.

3 – LTE-M, NB-IoT, and DECT NR+.

Required when <mode> is 1. If a matching %TXSELFCAL command has not been executed with the correct mode settings, %XFSSYNC returns ERROR.

The following command example synchronizes and stores AT command configurations to the modem's NVM:
