Heewing t1 vtol configuration with DJI 04 pro

ArduPlane VTOL Plane
1

Hi, I’m new to the RC world and wanted to build a heewing that runs DJI 04 pro. I’m using DJI N3 controller and remote 3 and trying to use the DJI as my receiver. Wiring into the ardupilot I split the DJI power and ground to the VTX port for 9v, and and Tx and Rx to UART2 port, crossing the tx and Rx so Rx to tx etc. as I’ve seen in tutorials. Then the DJI Sbus wire and signal ground I ran to uart1, DJI Sbus to uart1 rx pin and ground to ground pin.

I’ve played around with settings in mission planner trying to get this setup configured but can’t get any output from my controller on mission planner or into the plane. I can calibrate the remote to my goggles and connect goggles to the plane and see out the camera with some DJI hud data like plane voltage and goggle battery but no OSD data from mission planner.

I think my wiring is following the right path but I just need to configure it right in mission planner. If anything stands out in my wiring setup or if anyone knows what I need to configure in mission planner I would really appreciate some help!

Hi @Jacob_Myler
what is the flight controller ?

3

I’m using ardupilot for my flight controller

4

What type of flight controller are you using to run Ardupilot on?

5

HEEWINGF405V2 is the flight controller

Sbus should go to the RCin. The RCin is RX2, beside all the servo pins.

7

I’ll give that a try when I get home!

Still not getting anything out of my remote on mission planner. I moved the Sbus wire from serial1>UART3(UART1 on casing) to the Rx pin on RC-in and signal ground to ground RC-in next to the servos.
From DJI air unit to serial2>UART1(marked UART2 on case) I have TX to rx and Rx to tx.

Then in mission planner I updated serial6>UART2(RC-in) to 23 for RC-in, 115200 baud rate, serial6_options 0
Brd_alt_config: 1
OSD:1
Serial2>UART1 (marked UART2) :33 DJI FPV

Rssi type: 3 RCChannelPwmValue

Try BRD_ALT_CONFIG,0

If that doesn’t work also try SERIAL6_PROTOCOL,-1

BRD_ALT_CONFIG,0 fixed it! Thank you so much.
