For ublox, the “signal” indicator translates directly to power levels. The manual is not very clear which power level though. > Random question, what does +CSQ report? MM uses +CIND because it gives > async notifications, which +CSQ does not. CSQ is usually tied to RSSI > though, which still isn't as useful for LTE. Interestingly, the ublox AT manual says, that +CSQ reports the RSRP in LTE, but it doesn’t seem to match the value returned by +CESQ. Perhaps I’m mixing something up. > You can use the Signal interface of ModemManager to pull out all lower- > level values from the modem. "mmcli -m X --signal-setup=<rate in > seconds>" starts and refreshes the signal values and "mmcli -m X -- > signal-get" gets the current signal values. > Give the --signal-* stuff a try and see if that works for you.

Yep, that’s what I did, it seems to work well. > Dan Thanks for your help!
