Set command

Syntax:

%XSYSTEMMODE=<LTE_M_support>,<NB_IoT_support>,<GNSS_support>,<LTE_preference>

+CME ERROR code

518 – Not allowed in active state.

522 – Band configuration not valid for selected mode.

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

<LTE_M_support>

0 – LTE-M not supported

1 – LTE-M supported

<NB_IoT_support>

0 – Narrowband Internet of Things (NB-IoT) not supported

1 – NB-IoT supported

<GNSS_support>

0 – Global Navigation Satellite System (GNSS) not supported

1 – GNSS supported

<LTE_preference>

0 – No preference. Initial system selection is based on history data and Universal Subscriber Identity Module (USIM). If history data or USIM configuration are not available, LTE-M is prioritized in the initial system selection.

1 – LTE-M preferred.

2 – NB-IoT preferred.

3 – Network selection priorities override system priority, but if the same network or equal priority networks are found, LTE-M is preferred.

4 – Network selection priorities override system priority, but if the same network or equal priority networks are found, NB-IoT is preferred.

Note: If <LTE_preference> is set to a non-zero value, <LTE_M_support> or <NB_IoT_support> or both must be set.

The following command example sets LTE-M and GNSS as the system modes. No preferred LTE mode set:

AT%XSYSTEMMODE=1,0,1,0
OK
