Set command

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. The configuration can be stored to NVM with the %XFSSYNC command when the Production Test Image (PTI) modem firmware is used.

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

The command is given separately for each phase. It is not necessary to send the command for each phase, which means it is possible to configure only one phase.

Syntax:

%XMIPIRFFECTRL=<dev_id>,<phase#>,<variable_number_of_phase_specific_parameters>

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

<dev_id>

The identification number of the MIPI RF Front-End Control Interface (RFFE) device given when it was introduced using the %XMIPIRFFEDEV command.

<phase#>

Number of the phase INIT = 0, ON = 1, OFF = 2, PWR_OFF = 3. All numbers must be given as decimals (hexadecimals are not allowed).

The following figure illustrates the RFFE device control in different phases:

In the figure, PAC/Switch refers to a register in an example antenna tuner that controls the tunable capacitors and/or switches.
