Yaapu telem with Converter Cable and F405 WTE Mateksys - Wiring and Setup

ArduCopter Copter 4.0
1

Hello Everybody,

I am struggling to find the right wiring and setup in Ardupilot

Current Wiring
X8R: SBUS → F4 SBUS
X8R: SPORT → YAAPU Converter
YAAPU Converter Yellow → F4 TX2 (I have also tried TX3)
YAAPU Converter Green → F4 RX2 ((I have also tried RX3)
YAAPU Converter Red → F4 4.5V
YAAPU Converter Black-> F4 GDN

Current Ardupilot setup (I have also tried SERIAL2 with TX3/RX3)
BRD_ALT_CONFIG = 0 (I have also tried 1)
SERIAL6_BAUD = 57
SERIAL6_OPTION = 7
SERIAL6_PROTOCOL= 10

The Ardupilot mapping from Matekys F405WTE provides that TX2/RX2 is SERIAL6.

Transmitter
I have copied / pasted an old model with the Yaapu widgets that I configured when using Pixhawk. I guess there is nothing to setup since it was working perfectly before.

==> Wiring + Setup is Not working. No telemetry data on my X12S.

Can anyone help me to confirm the wiring and setup?
Would be very greatful. :pray:

Thank you for your time.
Yohan

Set SERIAL6_OPTION = 0 (NO half-duplex)

Thank you Target0815.
I have changed the setting and it doesn’t resolve the issue.

I would be grateful if you can confirm that:

  1. the Green cable to RX2 and Yellow cable to TX2?
  • I have read in the forum that some users only plugged the TX and not the RX
  • I have read in the forum that some users plug the TX/RX in another SERIAL number (different from the SBUS).
  1. the red and black cables must be plugged?
  2. the BRD_ALT_Config = 0 and not 1 ?

Thank you very much for your help,
Yohan

You have already connected it correctly. Yellow goes to TX, green to RX, 5V and GND.

SERIALx_OPTION = 0 is also correct if the converter is used.

But, TX2/RX2 only work as RCin for the integrated ELRS RX (if the bridges from ERx to TX2 and ETx to RX2 are closed).

You must therefore use a different UART, e.g. TX3 / RX3 and then set SERIAL2_OPTIONS = 0. BRD_ALT_CONFIG can remain at 0 here.

I have now plugged:

  • the Yellow (rebuilt the pin) on the TX3 and the Green (rebuilt the pin) on the RX3.
  • the red on 5V (voltage checked) and black on GND

Then set:

SERIAL6_OPTION = 0
SERIAL6_PROTOCOL = 2 (default)

SERIAL2_OPTION = 0
SERIAL2_PROTOCOL = 10

I have also re-bind the R8X (CH1-8 Telemetry ON)
Unfortunatelly, I am still unable to discover new sensors on my transmitter.

Do you have any idea? Please

Again thank you for taking time,
Yohan

I have compared with my setup, the colors are wrong … Yellow goes to RX, green to TX.

Target0815 you are genius!!! It works :slight_smile:

For the sake a clarity of the other users, here is the final wiring and setup
Again thank you!
