%REL14FEAT set command

The set command enables the supported 3GPP Release 14 features on the modem.

The %REL14FEAT command is allowed only before activating the modem with the +CFUN=1 command. If the feature configuration needs to be changed, the modem must first be set to flight mode with the CFUN=4 command. Otherwise, the command returns ERROR.

The command configuration is stored to Non-volatile Memory (NVM) approximately every 48 hours and when the modem is powered off with the +CFUN=0 command. Values stored by the user can be overwritten by operator settings.

Active %XPOFWARN warning blocks the storing to NVM.v1.3.x≥2

Note:

All 3GPP Release 14 features are disabled by default.
Enabling Narrowband Internet of Things (NB-IoT) dual Hybrid Automatic Repeat Request (HARQ) enables also maximum TB size enhancement.
Enabling Release Assistance Indication (RAI) requires feature activation with the %RAI command.

Syntax:

%REL14FEAT=<mac_inact_monitor_support>,<as_rai_support>,<NB_dual_harq_support>,
<NB_max_TB_size_support>,<interf_cmm_intraf_rsrq>

The set command parameter and its defined values are the following:

<mac_inact_monitor_support>: 0 – MAC inactivity monitoring not supported; 1 – MAC inactivity monitoring supported
<as_rai_support>: 0 – Access stratum RAI not supported; 1 – Access stratum RAI supported
<NB_dual_harq_support>: 0 – Narrowband dual HARQ not supported; 1 – Narrowband dual HARQ supported
<NB_max_TB_size_support>: 0 – Narrowband maximum transport block size not supported; 1 – Narrowband maximum transport block size supported
<interf_cmm_intraf_rsrq>: 0 – Inter-frequency connected mode and intra-frequency Reference Signal Received Quality (RSRQ) measurements not supported; 1 – Inter-frequency connected mode and intra-frequency RSRQ measurements supported

The following command example sets support for MAC inactivity monitoring and inter-frequency connected mode and intra-frequency RSRQ measurements mode:

AT%REL14FEAT=1,0,0,0,1
OK
