    • RE: Setting up network interfaces

      @ryan_meagher You should be able to do this using the /etc/network/interfaces approach you mentioned. voxl-modem uses that approach in order to set a static IP for Microhard on eth0. This is what the /etc/network/interfaces file looks like in that case:

      # This file describes the network interfaces available on your system
      
      # The primary network interface
      auto eth0
      iface eth0 inet static
      	address 192.168.168.100
      	netmask 255.255.255.0
      	gateway 192.168.168.1

    • RE: Static IP address on eth0

      @SmittyHalibut That page may be outdated. You definitely can set a static IP on eth0, it is required for Microhard usage. For example voxl-modem uses the interfaces file here for setting a static IP: https://gitlab.com/voxl-public/utilities/voxl-modem/-/blob/master/config/interfaces

      It does require pulling down / up the interface on boot: https://gitlab.com/voxl-public/utilities/voxl-modem/-/blob/master/scripts/voxl-modem#L516 which may be a solution for @Sem-Andeweg

    • RE: How to install and configure OpenVPN?

      @Djalma-Ribeiro You can create a systemd service file and enable it to run on boot and have it execute the OpenVPN connection command.

      Here is an example on how we have used it in the past on a VOXL:

      [Unit]
      After=voxl-time-sync.service
      Requires=voxl-time-sync.service
      
      [Service]
      Type=forking
      ExecStartPre=/bin/sleep 2
      ExecStart=/usr/sbin/openvpn --script-security 2 --daemon --config /etc/openvpn/KEY_FILE
      
      [Install]
      WantedBy=default.target
      

      Won't be exactly the same as above but that's the general idea.

    • RE: Voxl 2 and Herelink Slow Video stream

      @Nicholas-Hansen In order to set an IP address at boot you could create a systemd service that runs a script similar to this portion of the voxl-modem startup script:

      https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-modem/-/blob/master/scripts/voxl-modem-start?ref_type=heads#L242

      You could probably highjack the doodle workflow if you really want to. It's pretty basic, it just waits for the network interface to enumerate and sets the IP address if it is different from what is set in the config file. It then monitors that interface and sets the IP again if it ever changes

      echo -e "\nWaiting for eth0..."
              rc=1
              while [ $rc -ne 0 ]; do
                  ifconfig -s | grep eth0
                  rc=$?
                  sleep 1
              done
      
              echo -e "\neth0 initialized"
      
              # loop and re-set IP if network interface goes down and back up
              while true
              do
                  # grab ip address from eth0
                  eth0_ip=$(ip -4 addr show eth0 | grep -oP '(?<=inet\s)\d+(\.\d+){3}' | head -1)
      
                  # if it's not what we expect, fix it
                  if [[ "$eth0_ip" != *"$DOODLE_IP"* ]]; then
                      echo "setting IP address to: $DOODLE_IP"
                      ifconfig eth0 $DOODLE_IP netmask 255.0.0.0 up
                  fi
                  sleep 1
              done

    • RE: VOXL 2 Ethernet and USB Hub Add-on with Doodle lab radio

      @shawn_ricardo Not really a better way at this point, I'd like to at some point just make the network interface able to be specified in the config file as opposed to hard-coded as eth0, but haven't gotten to that yet

    • RE: Voxl not connecting to QGC

      @PawelJ Yep, it should be either 14550 or 14551.

    • RE: error compiling voxl-vision-px4 from source

      I would rebuild using the master branch and do the following:

      You can use the opkg server in order to install the dependencies.

      In /etc/opkg/opkg.conf uncomment the line #src/gz dev http://voxl-packages.modalai.com/dev.

      Then, call opkg update

      • Install libmodal_json with opkg install libmodal_json
      • Install voxl-mpa-tools with opkg install voxl-mpa-tools
      • Back on your host pc, run ./install-on-voxl.sh

    • RE: QVIO unstable flight. Please help!

      @Daniel-Rincon Others will likely chime in, but OVINS allows you to run multi-cam VIO which in general will be more accurate than single-cam which is all that QVIO can do

    • RE: QVIO unstable flight. Please help!

      @Daniel-Rincon QVIO (voxl-qvio-server) and OVINS (voxl-open-vins-server) are two different VIO algorithms. Currently only one can be used at a time. If you take a look at /etc/modalai/voxl-vision-hub.conf you should be able to specify which to use.
