BF4 RC5, OminbusF4V6, remapped motors, 2 motors not working when dshot_bidi = ON

[wunderlins]

Describe the bug I have a 4in1 Typhoon32 ESC, it is 90° CW roated, therefore I have to remap the motor resources. When I test the motors with dshot_bidi = OFF in the motor tab, they work as expected. If I turn dshot_bidi = ON, motor 2 and 3 stop working.

To Reproduce Original (as of OMINBUSF4V6):

resource MOTOR 1 B00
resource MOTOR 2 B01
resource MOTOR 3 A03
resource MOTOR 4 B05

My Configuration:

resource MOTOR 1 None
resource MOTOR 2 None
resource MOTOR 3 None
resource MOTOR 4 None

resource MOTOR 1 B01
resource MOTOR 2 B05
resource MOTOR 3 B00
resource MOTOR 4 A03

Expected behavior Motor 2 and 3 should turn like 1 and 4 (otherwise it's bit an unfair work distribution ;)

Hi,the motor resources are personal,depend of what esc are you using. Wich is exactly your problem?trying to test Dshot bidir and rpm filter?

[etracer65]

Did you do set dshot_burst=off as required? Also the version of BLHeli_32 firmware you list doesn't support bidirectional telemetry. You need to use a beta version with the appropriate support.

Sounds like you didn't read and follow the instructions carefully. Please start here: https://github.com/betaflight/betaflight/wiki/Bidirectional-DSHOT-and-RPM-Filter

[wunderlins]

I actually did follow the instructions. I have used the recommended settings for my flight controller[1] as you can see in my diff above. The instructions, however are misleading, they mention i need blheli_32 v 32.6.x (i am using 32.6.0 which clearly apply according to your instructions). So you may change the instructions to say BLHeli_32 > 32.6.0.

I will re-flash my ESCs with newer firmware and report back.

BLHeli_32 > 32.6.0 flashed, works, closing, sorry for the false report.
