RSSI check : CSQ vs QENG: "servingcell"


I am using a Quectel EC25 modem and reading the RSSI value from the modem.

Wanted to ask what is the difference between getting the value from “AT+CSQ” command or via "AT+QENG=“servingcell” ?

Is one of them more recommended/accurate ?
AT+QENG="servingcell returns the accurate negative value in [dBm] and no calculation needed , unlike for the value getting from “AT+CSQ”[0-31].


Hello rozmanro, thanks for your quesetion on quectel forums
AT+QENG=“servingcell” command query LTE signal strength, AT+CSQ query GSM and UMTS signal strength. We recommand you use serving command read the RSRP value from module than RSSI, thank you.
