BF 4.0 RC2 - DALRC F405 motors 1 and 2 not spinning (Dshot Bidir)

[digex]

Describe the bug After installing BF4.0 RC2 and blheli FW 32.6.7 , with bidirectional dshot and rpm filters enabled, motor 1 and motor 2 doesn`t spin.

When I disable dshot_bidir all motors spin correctly.

To Reproduce install BF4.0 RC2 and blheli FW 32.6.7 , enable bidirectional dshot and rpm filters.

Expected behavior After arming motor 1 and 2 does`t spin.

This is installed https://github.com/betaflight/bidircfg/blob/master/DALRCF4.cf

seems to be the same problem like here: https://github.com/betaflight/betaflight/issues/7759

[digex]

Help. https://github.com/betaflight/betaflight/issues/7759#issuecomment-474729874 set beeper_frequency = 0 not working for dalrc f405 aio Motors 1 and 2 not spinning

[JSpielz]

I have this EXACT same problem.

While I was trying to test out the RPM filter/Bidirectional Dshot, motor number 1 wouldn't spin or boot up and motor number 2 would make the startup tone a couple of seconds after 3 & 4 and not spin as well. After a bit of troubleshooting, I realized that by turning " set Dshot_burst = on" my motors would spin normally and make the startup tone up at the same time. Once I turned dshot_burst back off and changed nothing, the same thing happened.

I started from 4.0 defaults and pasted the snippet for the DalRC F405 from the RPM filter page and that is when I noticed the issue. I didn't change anything else other than the PIDs. I even tried updating the firmware to the current latest build of 4.0 (3/22) and still the same thing.

I just wanted to let you guys know. Hopefully you can solve the issue.

Thanks so much for all your work on BetaFlight!

(I have a DalRC F405, JB30a 4-in-1, TBS Unify 5G8 V3, FlySky X6B, Foxeer Predator V3, Johnny FPV 2700kv 2207)

Same here i can confirm the issue.

[bobbfwed]

Also confirm this is happening. I'm using BF 4.0 RC5 on DALRC F405, and the 32.6.1 test code firmware for my DALRC Engine 40A ESCs. Motors 1 and 2 don't spin, and they don't seem to get startup tone.

[EnricoBara]

Confirm the same as @bobbfwed said

[VirtualEnder]

Fixed in PR #3 waiting on merge.

[bobbfwed]

Just tested it with RC6 and the newest version of commands on https://github.com/betaflight/bidircfg/blob/master/DALRCF4.cf and it worked great!

[Rclf]

same here on clracingf4 ,motors 1 and 2 do not spin. That is on 32.61

Also when connecting to blheli32 suite after check it sees only esc 3 and 4. When checking again it sees all 4 but on the first 2 I get input bad frames. I am reflashing all over both escs and fc, will report again

after applying

timer b00 1 timer b01 1 timer b04 none timer b08 none

dma pin b00 0 dma pin b01 0 dma pin b04 none dma pin b08 none

I get this status but still motors 1 and 2 are not spinning

edit 2. Nope, as soon as I set dshot_bidir=on motors 1 and 2 stop working, everything works when I set dshot_bidir=off.

my hex is KS_BLHeli_32_30A_Multi_32_61
