Set command

The set command subscribes or unsubscribes notifications of changes in signal quality.

Syntax:

%CESQ=<n>

Notification syntax:

%CESQ: <rsrp>,<threshold_index>

The command parameters and their defined values are the following:

<n>
0 – Unsubscribe signal quality notifications
1 – Subscribe signal quality notifications
<rsrp>
0 – RSRP < −140 dBm
1 – When −140 dBm ≤ RSRP < −139 dBm
2 – When −139 dBm ≤ RSRP < −138 dBm
...
95 – When −46 dBm ≤ RSRP < −45 dBm
96 – When −45 dBm ≤ RSRP < −44 dBm
97 – When −44 dBm ≤ RSRP
255 – Not known or not detectable
<threshold_index>
Index of Reference Signal Received Power (RSRP) threshold which is below measured RSRP value.
0 – RSRP is below the first threshold
1 – RSRP is between the first and second threshold
2 – RSPR is between the second and third threshold
3 – RSRP is between the third and fourth threshold
4 – RSRP is above the fourth threshold
With default thresholds 20, 40, 60, and 80, the measured value 70 leads to index 3.

The example command subscribes E-UTRA signal quality notifications:

AT%CESQ=1
OK

The example notification indicates a change in the measured average RSRP. The average RSRP is 62 and mapped to threshold 3.

%CESQ: 62,3
