Set command

The set command subscribes notifications of changes in Signal-to-Noise Ratio (SNR) signal quality.

Syntax:

%XSNRSQ=<n>

Notification syntax:

%XSNRSQ: <snr>,<threshold_index>

The parameters and their defined values are the following:

<n>
0 – Unsubscribe SNR signal quality notifications
1 – Subscribe SNR signal quality notifications
<snr>
0 – SNR < −24 dB
1 – When −24 dB ≤ SNR < −23 dB
2 – When −23 dB ≤ SNR < −22 dB
...
47 – When 22 dB ≤ SNR < 23 dB
48 – When 23 dB ≤ SNR < 24 dB
49 – When 24 dB ≤ SNR
<threshold_index>
The index of the SNR threshold which is below the measured SNR value.
0 – SNR is below the first threshold.
1 – SNR is between the first and second threshold.
2 – SNR is between the second and third threshold.
3 – SNR is between the third and fourth threshold.
4 – SNR is above the fourth threshold.
With default thresholds 16, 24, 32, and 40, the measured value 35 leads to index 3.

The following command example subscribes E-UTRA signal quality notifications:

AT%XSNRSQ=1
OK

The example notification indicates that the measured average SNR has changed to 39 and is mapped to threshold 3:

AT%XSNRSQ: 39,3
OK
