@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
@SmittyHalibut That page may be outdated.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
@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.
@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:
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
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
opkg install libmodal_jsonopkg install voxl-mpa-tools./install-on-voxl.sh@Aaron-Porter The VFC flight mode that will be entered when switching into offboard is dependant on what is specified in /etc/modalai/voxl-vision-hub.conf
Example here:
"vfc_submode_ch": 6,
"vfc_alt_mode_rc_min": 0,
"vfc_alt_mode_rc_max": 0,
"vfc_flow_mode_rc_min": 1700,
"vfc_flow_mode_rc_max": 2100,
"vfc_hybrid_flow_mode_rc_min": 0,
"vfc_hybrid_flow_mode_rc_max": 0,
"vfc_position_mode_rc_min": 1300,
"vfc_position_mode_rc_max": 1700,
"vfc_traj_mode_rc_min": 0,
"vfc_traj_mode_rc_max": 0,
In this example, VFC flight modes are monitored on channel 6
Depending on what position the switch is in, a different VFC mode will be entered
So for example, if the middle position of flight modes is set to "Offboard", when the switch is flipped into the middle position ~1500, VFC position mode will be entered
@bendraper We generally have to activate the SIM card by inserting it into either an android phone or iphone and activate it with the google fi app before using it with VOXL2
@Sarika-Sharma With the device powered and plugged in via USB, what do you see with lsusb?
@AidanGallagher With an M0130 USB breakout board
M0130: https://www.modalai.com/products/m0130-3?variant=48186331693360
You can use this cable:
MCBL-00085: https://www.modalai.com/products/mcbl-00085?_pos=2&_sid=0c5d87c5e&_ss=r
and get rid of the need for the doodle breakout board
@taiwohazeez Have you reviewed this doc?
https://docs.modalai.com/orqa-ghost/
You'll have to use the Orqa FPV controller, an ELRS commando will be incompatible with this receiver
@taiwohazeez What is the SKU of your drone? voxl-inspeckt-sku
Do you know what receiver is on your drone? Ghost and ELRS would require different receivers
@Sarika-Sharma If you're using a VM on windows in order to run Ubuntu you'll need to setup USB device pass-through from your host machine.
I would recommend running linux natively if possible
@AidanGallagher Can you post a picture of the setup you're using?
@MichaelH The issue is that users have seen GPS signal degradation when LTE/5G is running due to the placement of the GPS
@AidanGallagher Are you able to ping the doodle modem itself? Also double check you aren't trying to use an IP that is already being used on the doodle network
