Set command

Syntax:

%XRFTEST=<test>,<operation>[,<param0>,<param1>,<param2>,<param3>]

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

<test>

0 – RX.

<operation>

1 – ON.

0 – OFF.

Note: Always send OFF <operation> before sending another ON <operation>.

<param0>

3GPP band number. Use 24 for Global Navigation Satellite System (GNSS) reception.

<param1>

Frequency 100 kHz.

Valid range 6000–22000 (corresponds to 600.0 MHz–2200.0 MHz).

Note: If Carrier Wave (CW) is used, an offset of about 45 kHz for Narrowband Internet of Things (NB-IoT) and 300 kHz for LTE-M is recommended.

<param2>

RX signal power at the SiP antenna port.

Valid range from −127 dBm to −25 dBm.

<param3>

System mode.

0 – NB-IoT.

1 – LTE-M.

Response syntax when <operation> is ON:

%XRFTEST: <antenna_power>, <headroom>

The response parameter and its defined value are the following:

<antenna_power>

Measured power at the SiP antenna port in q8 dBm. q8 means that dividing the result by 2⁸ = 256 gives dBm.

The following command example enables the RF receiver for Band 1, 2140.0 MHz, −65 dBm, NB-IoT mode:

AT%XRFTEST=0,1,1,21400,-65,0
%XRFTEST: -17002, -16
OK

The following command example disables the RF receiver:

AT%XRFTEST=0,0
OK
