@Eric-Katzfey For turtle mode with a joystick you need to set VOXL_ESC_MODE to 1 and, while not armed, press a button and keep it pressed while arming. For flight modes that should all be handled through QGC.

@Jetson-Nano Are you using QGC to map joystick buttons to functions? What version of PX4 are you running on your FC v2?

@george-kollamkulam As far as question #1, no it is not possible to update to Ubuntu 22.04 on the VOXL 2 autopilot. Updates must come from Qualcomm and then we have to adapt them to the VOXL 2. However, an update to 22.04 is not available.

@garret As long as you see it has extracted all of the files that should be all that you need.

@garret This is the documentation you need: https://docs.modalai.com/voxl-px4-dev-build-guide/. As part of that this readme: https://gitlab.com/voxl-public/rb5-flight/rb5-flight-px4-build-docker/-/blob/master/README.md?ref_type=heads has details on how to setup the build environment.

@Hector-Gutierrez Can you just remove the propellers and actually arm?

@Hector-Gutierrez We have actually used HITL for exactly this purpose which is nice because then you can see the flight behavior in the Gazebo visualization. Unfortunately, it's not a trivial matter to get everything setup to make it work with offboard mode since you need to have the VIO data that Gazebo generates go to voxl-vision-hub.

@garret I have no idea what is necessary for VTOL but I would guess that there are probably some missing modules that you would need for that. You would need to do a custom build to bring in whatever is missing.

@garret We have not tried anything but quadcopter and I'm not aware of anyone else trying anything other than quadcopter.

@Riccardo Make sure that the 2 devices sharing bus 4 have the same i2c frequency.

@cguzikowski No, there is no Ardupilot configuration file needed in /etc/modalai

@garret Very likely. But you also have some errors on gazebo launch that I have never seen before so that could be part of the problem as well.

@garret I use the Sparkfun CAB-12977 and CAB-17240 for HITL and it works really well.

@Hector-Gutierrez Point a small fan at the VOXL 2 while you have it on your desktop. You need to have air flow. When it is on a drone and flying you get a lot of airflow from the propellers but on the desktop you should have a small fan.

@Jetson-Nano VOXL 2 does not have PWM out. You would need our IO expander board M0065 to bridge between UART and PWM. https://www.modalai.com/products/voxl2-io?variant=40610514206771

@cguzikowski Yes, we have tested Ardupilot with GPS and have customers using Ardupilot with GPS. However, I don't know that anyone has ever tried with an M9N unit so perhaps there is some issue with that. Can you try with one of these: https://store.3dr.com/mini-gps-ublox-max-m10s/?

@Hector-Gutierrez What branch are you trying to build? If you install dependencies from the dev repo then you should also be building the dev branch of voxl-vision-hub

@Avishkar-Seth It's kind of scattered around in the docs. But here is the high level architecture: https://docs.modalai.com/how-to-connect-voxl-to-flight-core/

PX4 cannot run on VOXL, only on VOXL 2. On an m500 it will be running on the separate flight core board.

@ashwin Are you looking to control the servo via PX4 or with some custom software? What will the servo be doing?
