@taiwohazeez The build flow should be like this:
cd voxl-mpa-to-ros2 git checkout dev git submodule update --init --recursive voxl-docker -i qrb5165-emulator ./install_build_deps.sh qrb5165 dev ./build.sh qrb5165 dev ./make_package.sh deb

I am not able to stream video on QGC from VOXL2 to Herelink via ethernet port . Is there any set up required on the herelink side in regards to the IP address? The Herelink controller is connected to my local wifi and is paired with the air unit. Im using an INSIGNIA USB-to-ETH adaptor to connect the VOXL2 to the Air Unit.

Hi @Ege-Yüceel,

We usually create a volume to those headers when doing something like this but you can install the libmodal pipe package inside the docker container like this if you want.
wget http://voxl-packages.modalai.com/dists/qrb5165/sdk-1.5/binary-arm64/libmodal-pipe_2.13.1_arm64.deb dpkg -i libmodal-pipe_2.13.1_arm64.deb
**Note change sdk-1.5 to whatever sdk version you're on

@Eric-Katzfey Thank you for the reply,
If I understand correctly, the example you provided shows MAVSDK running directly on the VOXL — so on the drone itself. However, we want to run our script on a separate PC to be able to control all drones at once. We're not sure which port to use to communicate with PX4 while also taking advantage of the relocalization handled by VOXL.

Thank you again for your help!

@Mastermind That sounds like it would be possible, but obviously depends on the driver of the wlan adapter you choose. You would need to implement the bluetooth broadcast portion of Remote ID. The source code for voxl-remote-id is here and only currently supports the Wifi portion of Remote ID

@relevinsky reposting my answer from another thread:

The VOXL SDK projects aren't meant to be built on VOXL2 itself. We offer a few different docker images to build on a PC, voxl-qvio-server on VOXL2 is built using qrb5165 emulator: https://docs.modalai.com/voxl-emulator/#install-the-voxl-emulator-docker-image

while some other projects are built using voxl-cross: https://docs.modalai.com/voxl-cross/#install-pre-built-voxl-cross

@Alex-Pabouctsidis Nice! That whole process and API will be cleaned up in the future but looks like you were able to figure it out. All of the actual I/O driver code is baked into the sensors DSP image. As Qualcomm licensees we have access to it (and build that image) but we cannot share it.

@relevinsky For now your best bet will be to get an add on card that has a UART available for the applications processor. Future software releases will provide access to a UART on the DSP (As long as the flight controller isn't running) but that is not available today.

@Filip-Slezak-0 The standard way to install px4 is via a Debian package. You can look at our px4 "wrapper" project to see how we create the package here: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-px4/-/blob/master/make_package.sh

Looking at what BlueOS is setup to do...it might be easier to modify modalAI's voxl portal than to get this to work with the current setup.

The things I am looking to add immediatly is log download and additional ways to get information and status on voxl services such as journalctl logs

@relevinsky

What steps are you doing to compile the voxl-tflite-server code? It should be done within the voxl-cross Docker image. Also why SDK 0.9?

Let me know how I can help.

@rsr4z , voxl logger will create different directories and files for different data that it will be logging, so using a single socket for this will now work.

If you REALLY want to have the log files saved directly to your PC and your network connectivity has the bandwidth to do it, then you can potentially map your desktop as a network drive (using sshfs or something like that). Then you can save your logs to the network drive. However, you should be aware of the following potential issues:
ssh is encrypted, so encryption of data will take some additional cpu usage on VOXL (proportional to the amount of data) network-mapped drives are not always reliable, especially if you connection is not reliable, but there are sshfs flags you can try to automatically reconnect, etc.. if there is not enough bandwidth to save the data over your network connection, voxl-logger can get occasionally blocked and will drop packets on the MPA side
Another option you can consider is saving the logs on voxl, and then using periodic rsync to get the data to your PC. rsync works over ssh as well. I just did a quick search and this came up (i did not try it):
fswatch -o /src | xargs -n1 -I{} rsync -a /src /dest
(https://stackoverflow.com/questions/12460279/how-to-keep-two-folders-automatically-synchronized)

you would need to copy your voxl2's key onto your desktop so that you don't need to enter your password every time..

Finally, if you did not want to write to the VOXL2's drive at all, you could save the logs to tempfs (/dev/shm) and then rsync from there to your PC and have rsync delete the files after syncing in order to avoid filling up your RAM, but you have to be careful and not delete files that are still being written by the logger..

Hopefully this gives you a few options to think about..
