BlHeli_S passthrough

ArduCopter Copter 3.6

Hi!

Help please on setting up the ESC with the firmware “BlHeli_S”. BlHeliSuite does not detect connected ESC, the screenshot shows the Arducopter settings and the error that BlHeliSuite gives. ESC definitely working through BetaFlight all programmable.

Me too facing the same problem.
ESC-Special Edition Racerstar REV35 35A BLheli_S 3-6S 4 In 1 ESC
FC-
Pixhawk clone [white shell] 2.4.8
Tried one shot 125 & D shot 150.

Since around 2 month with the last copter beta the BlHeli_S passthrough its not working anymore here, too.
I can’t remember exactly from whats release its stopped working but it was working in the past!
(I’m using a pixracer)

Hi all

I have updated the firmware ChibiOS and the same thing happens to me

I followed the instructions of the wiki:
http://ardupilot.org/copter/docs/common-dshot.html?highlight=blheli

And it does not work,

my hardware

Clone Pixhawk [white housing] 2.4.8

regards

Please dev have a look at this, already 4 people reports its not working, I’m quite sure its really easy for all to try bluheli and verify this issue.

I had the same issue as well.

There is an open issue on this, I think it will be addressed when some developer will find the time to do so

I have the same issue.
BLHeliSuite is connecting but can not read the ESC setup.

Assuming it’s BLHeli_S (or just BLHeli) it’s not going to work. BLHeli_32 works. I use an old Naze32 FC to program those.

11

I mean BLHeli. In Beta/Cleanflight passthrough is working. I hope they will fix in soon.

12

I am using kaute F4 and blheli_s on freestyle copter. Wires are soldered and passthrough does not work. I have to flash it with betaflight every time I want to change ESC settings and then go back to arducopter.

13

It’s not broken… It’s just not supported… Only 32 is supported.

14

Get yourself a cheap Naze32 board and us it for ESC programming. They are <$15

15

The whole point of passthrough is to program ESC w/o having to disconnect wires from FC on compact builds where everything is soldered

16

Well sure I know that. But Ardupilot isn’t going to work with BLHeli or BLHeli_S and having a dedicated FC for programming is a better solution I think than flashing different firmware. But then I have been using an old Naze32 board for this purpose long before Ardupilot supported any passthrough so it’s routine.

17

The arducopter manual says:

Now connect a USB cable to your flight board and use BLHeliSuite on Windows to connect. You will need to use BLHeliSuite32 for BLHeli_32 ESCs, and BLHeliSuite16 for BLHeli/BLHeli_S ESCs.

18

But it doesn’t work with BLHeli_S anyway does it? The manual/Wiki is not always up to date.

19

I think it is a lot less hassle to re flash firmware than partially disassemble the copter, unsolder and resolder ESC wiring just to change ESC settings.
But using Naze32 could be a good option for initial ESC programming before assembly. What firmware can I use with Naze32 for passthrough ESC programming?

20

Oh, that’s not good… I don’t know who edited that manual page, but I do know from reading around the forums that no one ever worked on making it work w/ anything other than blheli_32…
I would say that is a pretty serious issue that the manual is wrong. Don’t want people making design decisions based on that, only to find, as you have, that it doesn’t work.
