      @RSAUser1 It's not something I've tried, but I assume it would work in the same way you would do it on another Ubuntu 18.04 device.

      @RSAUser1 said in Sierra Modem not showing in Device Manager/wds errors:

      @tom I just heard back from Sierra wireless and they are stating this is an issue on your guys side. Not sure how to proceed. Any insight on the path forward is appreciated. Maybe if we can speak with you and Sierra wireless in a joint chat that would be easiest?

      Thanks.

      Sorry just want to add. We were able to get a connection to our emulator but only when the modem status shows:
      voxl2:/$ systemctl status -l voxl-modem
      ā— voxl-modem.service - Modem Initialization
      Loaded: loaded (/etc/systemd/system/voxl-modem.service; enabled; vendor preset: enabled)
      Active: inactive (dead)

      Which seems to have confused me more. What we did was disable the vision-hub , just to allow another service to start (in theory) but then disabled modem, adb rebooted, enabled modem all while we were injecting the 5G signal (only band n5 works but handovers to supported bands do work).
      Any deviation from these steps does not work, like if we reboot then inspect-services or anything besides just enabling modem it will not connect. Is this because if the drone loses power or anything the first thing it needs to do is find the network (another theory)? Even if we are connected and turn of the 5G cell from our side and turn it back on the chipset does not reconnect and it looks like it is not trying to find a cell.
      Looks like this is on sierra wireless, is there anyway we can have a joint chat to troubleshoot this?

      Thanks!

      @RSAUser1 yeah i'd probably pass to @tom . The modem is seems connected, otherwise you wouldnt see wwan0 come up. Once I had access to AT commands I ditched QMI which I think is more or less a wrapper for those commands anyway.
