        Thanks, Alan.  I had already done what you suggested but still no joy.  A1 = 4.75 and mode is D16 on Taranis.

        Wiring is per instructions and I have solid orange LED on Teensy.  I do not have 3DR radio connected at this time.

          Re-flash the Taranis to the latest firmware.

          Re-load the Teensie from the latest (V1.3) zip on this thread.

          Check what is going back to Mission Planner via USB - GPS lock, voltages etc.

          Sorry, that has about exhausted my knowledge of the subject. Don't give up.

    Help needed!

    Installed MavLink_FrSkySPort_1.3.zip

    Cut trace, applied power to Teensy 3.1, installed Teensyduino, etc.

    When I upload MavLink_FrSkySPort from examples, I get the following error: 

    MavLink_FrSkySPort.ino:47:25: fatal error: GCS_MAVLink.h: No such file or directory
    compilation terminated.


    I can run other Teensy examples OK using Arduino IDE 1.0.5.  What am I missing?

      It is on the 6th page of the thread:

      It's simple...do like this:

      1. Download and extract the MavLink_FrSkySPort_1.2.zip file   (for example. to your desktop)

      2. Open Arduino software and in  menu File/Preference change the sketchbook location to the place you extracted the .zip file, press Ok

      3. Restart Arduino and in the menu File/Sketchbook  select  MavLink_SkySPort

      4. Compile and transfer to Teensy

      ( You must have installed the Teensy extension for Arduino  http://www.pjrc.com/teensy/td_download.html  )

        I think that the real problem is that I used the Arduino IDE to install the library.  I manually moved MavLink_SkySPort to the proper location and the error went away.

    @Rolf

    Many thanks - I have now got the basic setup working with my 433 telemetry in parallel. What this means for me is that I can move on from mission based flights glued to the laptop to just flying around - this is backwards I know but I am a much better tech than pilot.

    I will add the little snippets of code from the thread to expand the telemetry via my X8R and I am really interested in the LRS possibilities. I have a home made DTF UHF 1W TX and a couple of RX - not much opportunity for long range in Northern Germany but the tech is fascinating. Also many thanks to the contributors that have added to the quality of the thread.

    Hi all

    great work on this converter.

    Just a small question. I was looking at the source code for Arducopter and in there there's a provision to run user code (UserCode.pde).

    In the case of the PixHawk that exposes Serial 4 and 5 wouldn't it be easier to have the code running inside the PixHawk and just connecting one of these serial ports to the X8R ?

    Might be a dumb question, but I'm just starting at this....

      Answering  my own question, found on the NuttX source files an implementation of frsky telemetry output at the drivers/frsky_telemetry dir which at first sight appears to output to a serial port the telemetry data already packaged for the frsky. It appears it is started by command line with an argument defining the output uart.

          Hi Luis,

          I believe the frsky_telemetry app built into the PX4 firmware is for the old FrSky hub protocol, not the new SmartPort protocol. 

          I was thinking about adding a new app for the SmartPort protocol as the software wouldn't be too difficult using the existing apps as a template. But I believe the problem is the UART on the Pixhawk doesn't support the inverted serial needed for the SmartPort protocol. I haven't had a chance to look into this further though.
