Talon F7 V2 no bidirectional DSHOT possible

[MartinFPV]

Describe the bug When trying to activate the bidirectional DSHOT under Betaflight. Turn on 2 motors only briefly, then nothing happens anymore. Before activating the Bidirectional DSHOT, all 4 engines were unremarkable.

To Reproduce https://youtu.be/rpyD-B7AGoQ

Expected behavior All 4 motors should behave normally with activated bidirectional DSHOT.

inverted DShot needs 32.63, doesn't it?

[MartinFPV]

Rev32.6.3 for inverted bidirectional dshot is only needed from Betaflight 4.1, right? At 4.0.2 it is still the uninverted 32.6.2.

[RipperDrone]

of course, thought you were trying inverted. My bad, sry...

[etracer65]

Since that board uses the CLRACINGF7 target, it would be safe to assume the same restrictions apply.

[MartinFPV]

But if that were the case, the same hardware conditions apply for the TALON F7 as for the CLRACINGF7, why do only 2 motors run for a short time. Then 3 motors would have to start shortly, right? I think that there is more behind.

To the Schreenschots: bottom with bidirectional dshot enabled. above without activated bidirectional dshot

@MartinFPV: Yeah, looks like this is an incorrect clone of the CLRACINGF7. Since the manufacturer does not provide their own target, or collaborate with us on developing one, there is not much we can do to fix this. You should probably take this up with the manufacturer.

Okay, thanks for the information, I wrote HeliNation's support today.
