the latest suite rev i could reliably connect with using ardupilot is 32.6.1.1 . there‘s a recent commit for higher revs support in master, i personally didn‘t get it working though:
Thanks to you all. I will try the older version tomorrow. Is this thread the best place to monitor for the new released solution? I will report my results here.

The older version worked for me too.
Could you please add label for ArduPlane aswell. It is also affected.
Thank you

Hello Doctor Basti. All I did was ask the gurus over there for help. I did not fix the issue personally. I wish I had the skill 
How are you doing man? Come visit us in Hungary. I would be so happy to see you. Fly and factory tour. What say you?
@pompecukor
hey alex, i‘m doing fine personally, job turbulences don’t leave much room for hobby stuff this year though, even had to cancel this year‘s trip to france 
hoping for more flexibility in 2020, would be great to see arace live! hope you‘re doing fine too and business is going well!
thanks to steffen and achim for fixing blhelisuite issues!
Is there much change form 1.0 to 1.5?
I mostly believe - if it aint broke don’t fix it.
Blheli _32 Suite 32.6.1.6a is the current version. It will not connect to my Pixhawk running arducopter 3.6.10, Been working on this for two weeks without any success.
Anyone have an older version of Blheli_32Suite? As a closed source the older versions are not available.
I have tried 32.6.4, but again, no connection. Accoding to the BLH log file the connection fails on the line “MSP_API_Version”
Hey Hquarter, try this
Dear All
Trying dozens times and cant do my BlHeli_s work with my PIXHAWK. The motors do not spins, and passtrough does not work too.
Please anybody to send a quad parameter file to help me?

You shouldn’t have any problem getting them to spin but you can’t use BLHeliSuite 32 for BLHeli_S ESC’s. Need the 16bit version of the suite.
Better if you post your parameter file.
Dear , tkyou for the response.
I’m shure I have some config problem, due the motors does not work and cant do the passtrough. I tested with 16bit version, and it does not work too.
I goona post parameter file late afternoon .
Tks again

You posted this question is 3 different threads? That practice will discourage help. And if you are using Copter V4.0.3 it doesn’t belong here.
Dear Dave, I’m sorry !
Any thing can I do?
I’m really desperate to find a solution.
I`m grounded for long time.
I`m sorry again
Passthrough with BLHeli_S ESC’d likely will not work. I have a couple craft with those ESC’s and I use an old Naze32 board running Betaflight for setup/configuration. BLHeli32 is no problem.
BLHeli esc only connect to AUX pinout only? if OCTOROTOR configuration how to connected remains ESC cables?
default with AUX1 connected ESC detected as ESC no1 .but with SERVO_BLH_MASK = 15 (channel 1,2,3,4) not detected in BLHeli_32 suite software.
For Octorotor you need to use CUAV X7 or Nora boards, those have 8 aux pins. And connect the aux pins as always.
i have CUAV V5+ and CUAV V5 nano can we configure in this board?
If it has 8 aux pins, then yes.
