Is it possible to send MAVlink telemetry to a serial port in OpenTX?

[arikrupnik]

I understand that LUA has access to serial port(s) in OpenTX/EdgeTX. Is it possible to forward MAVLink that comes in through FrSky telemetry to a serial port on Taranis or TX16S, so that the user could then forward that to a laptop? The alternative is to have a separate telemetry radio onboard (e.g., SiK) which feels silly since telemetry is already streaming down over SPort.

Hi, there's no mavlink coming in so no way to forward it. This widget uses custom frsky telemetry as documented here https://docs.google.com/spreadsheets/d/1oFv5zSl10wyR0LOcCChDdy9peIRNkbaEBrsHDQ0ZdmE/edit#gid=0

Thank you for explaining this, Alex. I had the wrong idea about how this worked!

To do this, simply connect bluetooth to the radio, and select telemetry transmission in the settings. The script is not needed here.

...what you get is a frsky telemetry relay which will not work if using my script in parallel because my script uses custom telemetry frames, you would need to enable SERIALn_PROTOCOL 4 (unless out there there's a telemetry app that understands passthrough telemetry I'm not aware of)

I could write a decoder for my Python, but I don't think this approach is going to work for my application, which includes a PTZ camera. I understand that GPS effectively updates at 0.5 Hz (1 Hz but alternating lat/lon). This is too slow to drive a camera. It was a neat idea, but I don't think it's going to work. I'm back to two separate radios.
