VOXL2 Doodle Labs Nano Integration

Jetson Nano

I have been recently working on integrating different communication modules with VOXL2 for custom applications. I'm planning to integrate Doodle Labs Nano along with VOXL2 due to smaller form compared to Mini. I have few questions regarding the same,

In ModalAI documentation I see that, there is a demonstration shown with Doodle Labs Mini [link]. When integrating Nano, would it be the same connections in terms of hardware interfacing?
My airframe setup includes a Flight Core V2 as an external flight controller along with VOXL2 as compute. In this case, where should, where should I connect the Doodle Labs mesh radio to? Would it be VOXL2 or Flight Controller?

@Jetson-Nano I haven't used the doodle labs nano myself but it appears like the pinout is the same as the mini so the same cable should work.

In the external_fc case you'd connect the doodle radio to the VOXL2 and then use configure voxl-vision-hub and voxl-mavlink-server to expect data from an external fc as opposed to onboard px4

Hi @Tom, thanks for reverting!

I have a few more questions regarding telemetry data streams, specifically w.r.t DoodleLabs module on the VOXL2.

In my current air-frame setup,

I'm using a ELRS 2.4 GHZ telemetry setup connecting to FlightCore V2 for RC Telemetry inputs and another wifi-telemetry for low-latency transmission of video data stream to ground control station. With this scenario I'm planning to replace Doodle Labs as a single unit telemetry module and want to understand,

Does the video feed use a separate data stream from the command and control (C2) link in telemetry communication? Or are both transmitted over the same link?
Also how is the data stream for MPA Camera interface being streamed as RTSP being sent to Ground Control Station?

For example, when using the Herelink Radio, the video feed is sent over a separate Ethernet data link, while the command and control signals use an SBUS or UART connection.

@Jetson-Nano If you end up switching from ELRS + wifi to just doodle labs then both video and C2 will be sent over the same link. Therefore if you lose doodle labs connection, you will lose both video and C2. If you want to do C2 with doodle labs you'll have to use some sort of USB joystick connected to your ground control station, if it doesn't already have it built in

In order to stream rtsp video from a voxl-camera-server MPA pipe you can user voxl-streamer: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-streamer
