Flight Core V2 - VOXL ESC 4in1 Integration

[Jetson Nano]

@Alex-Kushleyev ,
Thanks for the clarity, I also went through the same process and was not able to find any way to forward the message to ESC through external FC.
If you could help with a work around this approach it will be really helpful. I can test it out and get back to you.

@Alex-Kushleyev
just a thought, the data from Voxl2 is transfered to FC. so you can convert them to specific msg type and forward it to external FC and External FC already has modal-io-bridge, it can forward the data to ESC. There will be need of conversion of msg types multiple places, for handling and forwarding.
the External Fc has turtle mode running on it, will it setup affect it.

@Jetson-Nano , there is probably more than one way of getting this to work, but I have been told that with the new approach that we have just implemented (being tested now), the mavlink tunnel should take care of routing the LED data from VOXL2 to FC V2 to ESC.

I asked my colleague to help describing how to test this.

@Alex-Kushleyev Thanks for the help. I will also test it out and get back with the results as soon as the approach is shared.
Can you also help me with finding clarity whether turtle mode will be affected by this setup.

[Alex Kushleyev]

@Jetson-Nano , As far as I know, turtle mode should work the same when running PX4 on VOXL2 and FC V2. Have you tested it? The LED command should not interfere with the turtle mode.

I have not actually tested the turtle mode on FC myself, but the code that is running in voxl-esc px4 driver is the same, so as long as you are entering the turtle mode correctly, it should work.

@Alex-Kushleyev I have not tested turtle mode with Voxl2 - FCV2 setup. I have tested with the Voxl2, internal PX4 server.
I will test it out and get back to you.

@Alex-Kushleyev , I tested the turtle mode out and it is working fine.

Once the approach for LEDs are shared, I will test it out .

I had an additional query, while we are using Telem for FCV2 and ESC communication. Will the PWM output (8 pinout) still be transmission and can we access the data.

@Jetson-Nano The updated voxl-io-server version is here: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-io-server_0.0.5-202502191136_arm64.deb. The updated FC v2 image is here: http://voxl-packages.modalai.com/dists/fc-v2/dev/modalai_fc-v2_1.14.0-2.0.95.px4. I have only tested with PX4 running on VOXL 2 but it should also work with external FC v2.

@Eric-Katzfey thank you for sharing the data.
I tried flashing the voxl-io-server you mentioned, but I got the following error.

@Alex-Kushleyev @Eric-Katzfey
can you check the above mentioned error.
