BLHeli Passthrough is Non-Op

[kelleysislander]

Current Behavior

Using the newly added Holybro Kakute f7 HDV target connected in the Kakute F7 HDV / Tekko32 F3 HDV ESC stack, I and was able to connect to the ESC's in BLHeli32 configurator via Betaflight on BLHeli Passthrough with BF 4.1.2 on the board... BUT, I was not able do the same with iNav 2.4.0 on the board. I received the "Found no valid ESC configuration"

Steps to Reproduce

1. Flash iNav 2.4.0 and connect to the ESC and connect to the USB of the computer, get a port with USB Serial Device shown in Device Manager on Win 10
2. Open BLHeliSuite32_32709 or BLHeliSuite32_32710 configurator and attempt to connect in the usual fashion. You will not connect and will receive the "Found no valid ESC configuration"

Expected behavior

As a user I should be able to connect the ESC's via BLHeli Passthrough on iNav 2.4.0

Suggested solution(s)

Restore the functionality

@kelleysislander please provide INAV diff output!

[kelleysislander]

Ok, sure...

I’ll do it later today after I get back home from work.

Cheers,

Bill

I had the same problem. But then I noticed that it always does not work when I connected to the INav Configurator before. If I connect the FC and then start BLHeli32 configurator directly, it works for me.

[kelleysislander]

Thank you... tried that anew since you suggested... still unable to connect ;) Did that work for you on the exact same setup as described above and pasted below?

Kakute F7 HDV / Tekko32 F3 HDV ESC stack

[jadirc]

I noticed this on a Matek F411 Wing FC with a Racestar 40A BLHeli32. Just thought this was a general behaviour.

[DzikuVx]

Just checked with Kakute F7 (this is the same hardware minus OSD) and passthrough is working. This is probably a timing problem: I2C processing for BMP280. I2C on 400khz takes too much time and messes passthrough timings. Your options:

• increace i2c_speed to 800khz
• or lower looptime to 500

[kelleysislander]

Thank you for that solution. It potentially fixes myself and the two others that commented on the #5472 issue.

How will all the other users know to look here to find the answer?

Can you possibly build this fix into the FW for this problematic board?

Thanks,

Bill

@DzikuVx I have the F722-PX and have the same issue. I've set looptime to 500 and still no dice. I've also tried disabling the baro.

[giacomo892]

INAV 2.5 on F722-PX All working fine

[kelleysislander]

The issue was raised on 2.4.

Glad to see it works once more on 2.5.

Reopening.

In TG chat we figured out that BLHeliSuite32 1.0.0.2 is requesting motor config using MSP_MOTOR_CONFIG which is unavailable in INAV. BLHeliSuite32 1.0.0.1 is not doing this and thus is working fine.

[4712]

@digitalentity BLHeliSuite32 xl/m 1.0.0.2 and 32.7.1.2 is restructured in some parts. Need to dig into it ...

[4712]

@digitalentity Fix will follow shortly in BLHeliSuite32 xl/m 1.0.0.3 and 32.7.1.3. EDIT: Done.

[digitalentity]

Awesome, thank you so much @4712!
