There is a requirement that I need to monitor the signal strength Router using Sierra EM7565.
I tried 2 methods:
- AT command: took ~1s to get the data.
- qmicli -d /dev/cdc-wdm0 --device-open-proxy --nas-get-signal-info
QMI took 300-500ms to get the data.
So I wonder if there is any way to get faster? (100ms)
