As I said in my other email on this topic, ConnMan just passed the value
from oFono forward. You need to look at the oFono code what is doing
with the RSSI information. qmicli seems to interact with the modem
directly so that means you might see a different value.
Thanks,
Daniel

Almost forgot about this patch. It's applied now.

Hmm, I need to look at it again. Forgot everything during my holiday.

Here your modem has probably crashed, right?

Just make sure ofono is stopped before running ofono.
# systemctl stop ofono

No, quite the opposite. It pretty much indicates that the SIM is
activated and it is in the process of connecting to the network.
Don't be confused by the GPRS terminology, there. I think even for LTE
you'll get this message while attaching to the default bearer.
Is that the last message in the log? If yes, I would run with debug
output and check what's going on in more detail.

Right, I lost LTE connection at that time.

Hmm, that is too difficult to use qmicli, it is not practical to stop
ofono every time. Are there any workarounds without stopping ofono?
Googling internet, followed suggestion to use qmi-proxy, but I still
could not get that work either:
# qmicli -p --nas-get-signal-strength --device=/dev/cdc-wdm0
error: couldn't open the QmiDevice: Couldn't spawn the qmi-proxy
The qmicli seems showing complete different values, but it did make
sense than the values from connman dbus query:
[/dev/cdc-wdm0] Successfully got signal strength
Current:
Network 'none': '-128 dBm'
RSSI:
Network 'none': '-128 dBm'
ECIO:
Network 'none': '-2.5 dBm'
IO: '-106 dBm'
SINR (8): '9.0 dB'
So RSSI from comman dbus query was false, right?
What is the normal methods you guys to measure the 4G LTE signaling strength?
Thank you very much Jonas,
Kind regards,
- jh
