Set command

The set command writes the XMIPIRFFECTRL configuration to nRF91 RAM memory.

The command is given separately for each use case. It is not necessary to send the command for each use case, i.e. it is possible to configure only one use case.

Generic syntax:

AT%XMIPIRFFECTRL=<dev_id>,<use_case#>,<variable_number_of_use_case_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 MIPIRFFEDEV (see SiP-external MIPIRFFE device introduction %XMIPIRFFEDEV).
<use_case#>
Number of the use case. INIT = 0, ON = 1, OFF = 2, PWR_OFF = 3. All numbers must be given as decimals (hexadecimals not allowed).

The following figure illustrates the RFFE device control in different use cases:

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