    • Building voxl-suite on Docker Image on VOXL

      I am trying to use a function in the voxl-io library on the VOXL and wanted to do this on an Ubuntu image on the VOXL. I was trying to install the package using opkg but I keep getting an error saying that both 0.2.0 and 0.1.1 are both can't be installed due to incompatible architecture. Is it possible to install these packages on the Ubuntu docker image or should anything that needs to be done using these libraries be done outside the docker image?

    • RE: LTE Modem "Feather is Disabled"

      Love the Lore and good thing to note! Last last thing, here is the link to an instance of me running dmesg if that's of any use.
      output here
      I'm going to keep trying to figure this out because this is a time-sensitive situation but if we will know for sure if it's a hardware issue once we get another modem to test it on. Thanks for the help thus far! Anything else I should try on here?

    • RE: LTE Modem "Feather is Disabled"

      This makes a lot of sense. I have seen this working before but now it just says feather is DISABLED until it power cycles and repeats. So if I understand correctly, after a few seconds, /dev/ttyUSB0 will be created and then the feather is enabled? Also random question: what is a feather exactly? I haven't heard of this before and I tried to look into it but I'm still confused!

    • RE: LTE Modem "Feather is Disabled"

      Nothing physically changed that I can recall, and unfortunately, we don't have extra modems though we ordered more modems. Last potential useful bit of info: when I ran dmesg, I saw errors relating to qmi pop up but I don't know what to make of them:

    • RE: LTE Modem "Feather is Disabled"

      Thanks, Tom, for the help! I really appreciate it! Is it possible that the serial port and the ports got renamed from /dev/ttyACM0 and /dev/ttyUSB0? I'm not too familiar with how these devices are generated or normal behavior for these devices. We have also noticed that this happened on two different VOXLs with the same v1 modem, so this problem seems to be with the modem and not the VOXL (though this is not something I am 100% certain about).

      And this will keep going if I let it, I'm pretty sure. In the /dev folder, /dev/qcqmi0 exists but /dev/ttyUSB0 doesn't exist.

    • RE: LTE Modem "Feather is Disabled"

      Thanks for the quick response! We are using a v1 modem.
      We ran voxl-configure-modem previously so that definitely could be the case. Here is the output for systemctl status -l voxl-modem:

    • LTE Modem "Feather is Disabled"

      Hi Guys,
      I was working on setting up the LTE modem add-on with the VOXL. I configured the modem properly and even connected to our VPN, and used QGC on the VPN server. However, when I rebooted the VOXL and went through the process of connecting the modem using voxl-modem --connect_to_network, I wasn't able to connect and got this as output:

      I know people previously have had this issue and the solution was that they improperly answered the voxl-configure-modem prompts. But I'm almost certain that this isn't the case because I was able to connect with no problems previously with no issues. What seems to be the problem from my view is that the devices /dev/ttyUSB0 and /dev/ttyACM0, which are supposedly the serial port and AT command port respectively, do not exist! I'm not sure if this is normal or if they are suppose to generate, but they do not show up when ls -la /dev is run:
