I’ve been trying to understand the features and limitations of ExpressLRS and Mavlink. Currently using ExpressLRS 3.2, Radiomaster TX16S/EdgeTX 2.8, Arducopter 4.4.
I know I get Mavlink messages via Yaapu, but no way to get real Mavlink protocol out (i.e. via USB/UART/TX Backpack). I can get generic telemetry out to a telemetry viewer but not Mission Planner. As I understand it, ExpressLRS is only receiving and outputting to Yaapu generic telemetry?
Is the only way to even get one-way (receive) Mavlink that is compatible with Mission Planner, to use a separate TX/RX module? Not currently needing two-way (i.e. control, mission upload, etc), just wanting receive.
2a) If so, since there is no timeframe for full Mavlink support in ExpressLRS, what is the cheapest/lightest way to obtain one-way Mavlink receive to use in Mission Planner?
Olli, I know your projects … But there are no easy and cheap modules that you can just buy ready-made. With DIY is of course much possible, but I think that was not asked.
Personally, I am also bothered by the fact that mLRS hardly has a community. I believe everything you write, but it is also so that exactly only one person develops the system. If you have no problem with it as a user, everything is fine …
I have been looking at this but I do not have a separate TX to run only mLRS right now nor do I want to mess with the DIY stuff on an expensive LR drone (yet, lol). It would be WONDERFUL if this could run on existing off-the-shelf modules, then I could at least just convert existing and maybe have an extra TX module to swap in, but sounds like that will never be the case due to hardware differences?
The ELRS fork listed above is a MAVLink flow control on top of a transparent bidirectional serial link. The application is to use a second set of rx and tx to transport MAVLink data (in both directions).
I was looking into this as well, but I saw a lot of comments about it not playing well with the same band RC link (i.e. 2.4 RC and 2.4 Airport), and I think even some that it caused issues even with different bands.
