Set command

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>

0 rsrq < −19.5 dB

1 – When −19.5 dB ≤ RSRQ < −19 dB

2 – When −19 dB ≤ RSRQ < −18.5 dB

...

32 – When −4 dB ≤ RSRQ < −3.5 dB

33 – When −3.5 dB ≤ RSRQ < −3 dB

34 – When −3 dB ≤ RSRQ

255 – Not known or not detectable

The index value of RSRQ can be converted to decibel with the following formula: Index x ½ – 19,5 = dB. For example, (32 x ½) – 19,5 = –3,5 dB.

<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 index value of RSRP can be converted to decibel with the following formula: Index – 140 = dBm. For example, 95 – 140 = –45 dBm.

The following command example reads the current signal quality, mapped Reference Signal Received Quality (RSRQ) 31, and Reference Signal Received Power (RSRP) 62:
