I would like to use AT+QCSQ command for EG21G.
I tried it and received next responses:
As far as I know the first parameter is the RSSI value. But RSSI is need to be in dB and be negative.
How can I convert the RSSI from this command to the real RSSI (negative in dB) ?
Third parameter in WCDMA case is ECIO value. Is this correct? Is it need to be converted or used as is?
Third parameter in LTE case is SINR value? How I convert it? As far as I know this value need to be in range 0 to 20+. I found two options:
- SINR = value / 5 (from my example 130/5 = 26)
- SINR = value/2 - 23.5 (from my example 130/2 - 23.5=41.5)
Which one is correct for EG21G?
