ELRS - Bidirectional MAVlink telemetry and RC control not working

Ground Control Software MAVLink

Hi everyone,

I tried to set up ELRS MAVlink telemetry and RC control feature, but the mission planner is not detecting the mavlink telemetry (Baud rate 460800, used a type-c USB cable to connect to the laptop).

I followed the steps mentioned here.

Below are the setup details:

Am I missing anything?

looks like you have your USB cable connected to the bottom charging port on your TX16S. use the top port near the antenna.

@flat-earther, Thanks for your quick response.

I connected using the top port only, I was charging the transmitter simultaneously.

If you use external module you have to use the module USB port, if you use internal modules then there is a bit of trouble and it would be best to join ExpressLRS Discord and look there in mavlik-rc channel.

If your module uses dip switches they also have to be set correctly (the default running configuration is wrong for MAVLink over USB)

I haven’t tried it and am not knowledgeable enough to know the answer for sure,
but could it be that the ELRS module is translating the Mavlink to CRSF for EdgeTX because EdgeTX doesn’t support Mavlink?
look at this Translate MAVLink telemetry to CRSF on the handset (rebased) by wvarty · Pull Request #2808 · ExpressLRS/ExpressLRS · GitHub

Telemetry mirroring from the internal module of an edgetx rc wont work.

You can either use usb via an external module (eg: ranger), or flash the internal elrs module backpack to the master github branch backpack fw and get a telemetry stream over wifi.

@Farkhod_Khikmatov , I got it worked but the param loading takes more time approx 4 to 5 mins, also the wifi keeps getting disconnected.

I followed this doc - Making MAVLink work with ELRS - Google Docs

I got this from ELRS discord channel. Let me know how it goes for you.
