Hi, I get 4G LTE RSSI from dbus connman service, I usually got about -61 I thought it was accurate. But today, we are doing a test to check 4G LTE RSSI based on different antennas, when connected to a antenna, the RSSI is about -61, when I did not connect to an antenna, the RSSI = -40 but the 4G LTE connection lost:
kernel: qmi_wwan 1-1:1.3: nonzero urb status received: -71. Apparently that RSSI = -40 was wrong in the situation of without antenna connection. I tried to build qmicli, but I could not get it running. googling Internet, people pointed out, it could not be run if the qmi is running by other services (ofono is running qmi on /dev/cdc-wdm0). # qmicli --nas-get-signal-strength --device=/dev/cdc-wdm0 error: couldn't create client for the 'nas' service: CID allocation failed in the CTL client: Transaction timed out Appreciate tips how to get qmicli running. Thank you. Kind regards, - jh
