Make sure your ESC is up to date. I’ve just been flying an F722 on 4.5.0 without issue.

[TheIsotopes]

@SteveCEvans I'm using latest BlHeli_32 32.10. I haven't seen anything more recent yet.

[haslinghuis]

Recommended firmware for BLH32

[TheIsotopes]

@haslinghuis
OK, that's new to me. I'll test it right away.
Have these problems with Blheli_32 already been discussed with the developer?

[haslinghuis]

@TheIsotopes
We are moving in direction of BlueJay and AM32.

Reported an issue here: https://github.com/bitdump/BLHeli/issues/713

[TheIsotopes]

@haslinghuis ok, the same problem also occurs with blheli_32 version 32.7.

Any other good advice?

[TheIsotopes]

@haslinghuis @SteveCEvans
For your information: I don't use any rpm filter or telemetry, so no dshot_bidir either.
I couldn't find the problem on my f405 quads, everything works as expected here.

[TheIsotopes]

@haslinghuis ok with set dshot_bitbang = OFF beeper and motors working again.

Should the newer versions of blheli_32 generally not be flashed or do the errors only occur with activated rpm filtering?

[haslinghuis]

O wow - did not think disabling bitbang would make the difference - so that's why I removed the post :)

Using 32.8 myself since 2019 - when trying 32.10 it did not work on my test subject (H750).

[TheIsotopes]

your firmware version only works also with set dshot_bitbang = OFF by using 32.7 and 32.10

[haslinghuis]

If you could test RPM filter is working with dshot_bitbang disabled we could update board configuration for MATEKF722MINI.

[TheIsotopes]

With your version from above and set dshot_bitbang = OFF the RPM filter will deactivated.

EDIT: same testresult with latest release version

[haslinghuis]

@SteveCEvans

Is there a way to improve dshot_bitbang = AUTO detection depending on dshot_bidir setting?

Same issue with SpeedyBee F7 V3, motors not spining at all (tested in BF Configurator, BlheliSuite32 and after arming a quad from radio). ESC are up to date (32.10). Moreover, enabling Bidirectional DSHOOT shows rpmfilter flag and Poblems with comunication occurs via USB and Bluetooth. After downgrading to 4.3.3 works as a charm.
BF 4.5 is definatelly realised to soon. Guys you have screwed.

Same issue with Airbot F7 and Blheli-S 4 in 1 Esc, everything works with BF 4.4 then “upgraded” to BF 4.5.0 No motor output , tried DShot 300 and DShot600. Flashed back to BF 4.4 everything works OK again ?

Did you try setting dshot bit bang = off?

[SteveCEvans]

To confirm, is this issue only being seen with bidirectional DSHOT disabled?

[haslinghuis]

In my understanding on some issues so far:

• bitshot_bitbang should be enabled for dshot telemetry
• when dshot_bidir is disabled bitbang should be disabled. ????
• most issues reported are related to F7X2
• blheli 32.10 also seem to generate issues, revert to 32.7 or 32.8

[SteveCEvans]

Just checked DSHOT600 with a Holybro Tekko32 F3 Metal ESC and TMOTORF7 FC.

With bi-drectional DSHOT disabled I see:

And with it enabled I see:

So, we're getting the expected inversion, telemetry is working, and the error count I'm seeing as zero.

The DSHOT value is stuck at zero though with bidirectional DSHOT disabled.

@TheIsotopes Please test #13633

@SteveCEvans working again, thanks for fixing it.

Is it normal when i’m arming quad on bench motors are slowly increasing RPMs and when i’m slowly move roll and pitch motors are changing smothly rpm but when i increase trothle to 50% motors motors stops to increase rpms and just respons to throthle normaly but roll and pitch causes motors to to make knock sounds? Wysłane z iPhone'aWiadomość napisana przez J Blackman ***@***.***> w dniu 12.05.2024, o godz. 22:00: Same issue with SpeedyBee F7 V3, motors not spining at all (tested in BF Configurator, BlheliSuite32 and after arming a quad from radio).
