Jumper R8 - Yaapu Telemetry

Hello All,

I am having some trouble getting Yaapu telemetry working with a Matek H743, Jumper R8 and Jumper T16.

The T16 is running OpenTX 2.3.11 with Multi Module firmware 1.3.2.61 and the Matek H743 is running Arducopter 4.07

When I go to discover new sensors on the T16 none are found. I’ve tested on all of the serial ports with serial protocol 10 (passthrough) and baud 57 and have swapped the TX and RX around just in case I had them mixed up. I have tested this on two different R8 receivers.

I was able to perform a test with a Radiomaster R168 that has an S-port connection just in an effort to test that the radio could detect new sensors. Sensors were detected by setting the serial protocol to 4 and setting half duplex but obviously Yaapu requires Passthrough telemetry to work.

Does anyone have any advice on what I could check or change to get this setup working?

Thanks
Brett

I have several R8s running from Matek F405 to my TX16s. They’ve been solid for me. You shouldn’t have to discover sensors for Yaapu telemetry to work. It should work on Serial protocol 10. It looks like you should have everything in order, but I’ll be in my work shop later today and I’ll go through all the settings I have for mine and see if there’s something missing.

What UARTs are you using on the H743?

Edit: Here’s my settings on the F405-Wing. (I know, not the same board)

|SERIAL6_PROTOCOL|10|
|SERIAL6_BAUD|57|

On the H743 mini or wing Serial 6 would be TX/RX4.

Hi Allister,

Thanks for the response.

The first serial connection I tried was TX/RX 7 which is serial 1 on the H743, when I couldn’t get that to work I tested all of the serial connections. All were tested with protocol 10 and baud 57, each time I swapped the TX and RX wires to make sure I didn’t have them the wrong way. Serial options were set to zero.

I have have re-tested TX/RX 4 (serial 6) with serial protocol 10 and baud 57 with no luck

The only other serial device I have connected is the SBUS from the receiver.

I have a Matek F405 STD that runs Arducopter that was in a now defunct project that I had Yaapu working with, I will use that to do a test.
