Set command

The set command returns received signal quality parameters.

Syntax:

+CESQ

Response syntax:

+CESQ: <rxlev>,<ber>,<rscp>,<ecno>,<rsrq>,<rsrp>

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

<rxlev>
99 – Not known or not detectable
<ber>
99 – Not known or not detectable
<rscp>
255 – Not known or not detectable
<ecno>
255 – Not known or not detectable
<rsrq>
255 – Not known or not detectable
<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

The example command reads the current signal quality, mapped Reference Signal Received Power (RSRP) 62:

AT+CESQ
+CESQ: 99,99,255,255,255,62
