Cannot Connect to 5G network
-
@chris_macdonald Okay, Verizon is not supported by Quectel. They won't allow a Quectel modem to connect to their network.
Internally we test with GoogleFi (uses TMobile)
-
@tom Gotcha. We had the same issue on our private network that does support Quectel.
-
@chris_macdonald Okay another thought, we had another customer who needed to unlock their SIM using a PIN in order to enable it: https://forum.modalai.com/topic/783/sim-card-pin-issue-for-lte-v2-module?_=1647023788468
-
@tom Just checked it on a phone and SIM card doesn't seem to have a PIN
-
@chris_macdonald What band is your private network using?
-
@Eric-Katzfey N41 (2.5Ghz)
-
Are there any forcing options? Can we force the drone to be on 5G only?
-
There are, however most carriers require an initial connection to 4G and then a handoff to 5G, therefore the modem may not be able to make a connection when setting to 5G only.
By default it is set to both LTE and 5G and will always prefer 5G if it's available.
We set this setting in
/usr/bin/set-mode-pref
which sends an AT command to the modem. -
@tom The link is coming back bad on my end. We will try a different carrier as well.
-
@chris_macdonald Oops, my bad. It is on board at
/usr/bin/set-mode-pref
