BLHeli-Setup for BLHeli - Q&A / Discussion

[donaldsneffe]

No, Achim, I am quite sure I did.
Right com-port, right BL Heli file, ...

Connecting Robbe-Box to computer, opening BL Heli, connecting Robbe box to ESC, connecting ESC to battery, trying to connect to BL Heli:
"Check ESC connection, power, signal" (this error message).
Disconnecting ESC from Robbe box, connecting battery to ESC, connecting (powered) ESC to Robbe box: everything is fine.

Checked this procedure several times.

What did I do wrong?

Sorry Walter, the last post was for pgleesonuk.

Robbe Box and Arduino are different.

[pgleesonuk]

this is the file I used

please can you confirm which pins I need to connect

[4712]

@pgleesonuk: Yes I will look.
Meanwhile: Please try to NOT connect the BESC and try Read!

[pgleesonuk]

Here is the log file

[4712]

Here is, how the C2 Connection should be:


Edit: Your wiring is wrong

OK, this is how I have it wired. I've tried changing red and white and this does not work either

My ESC works fine, and I can follow the TX programming for BLHeli V8. So I don't think I have broken anything.

My ESC is an Oversky (origin) 10A V3.

What order to I need to connect the Arduino board, the ESC and power to the ESC?

[4712]

Please look at Your wiring and my picture: it is very different!

The log shows: Connection to Interface is ok, but not connection to BESC.

[pgleesonuk]

I have fixed my wiring now. I realise it was wrong. It is now like your picture.

If I can't connect to the BESC what might be the problem? Do you know which way wrong the connector should go on this ESC?

[4712]

Did You power up the heli? You have to...

[pgleesonuk]

Yes I power up the hell, with the radio on, so it's ready to fly. Then the USB interface, then connect the interface to the hell

[4712]

The connection seems to be the way it should as shown here:
http://www.overskyrc.com/index.php?m...roducts_id=328

But re-check the connections at the Arduino and please post a new picture. I cannot see what You did...

[pgleesonuk]

Here is my wiring now.
I used servo connectors so I can change it if required

thanks for all your help

[4712]

Seems to be OK, I have no further Idea for now...

EDIT: May be, You recheck all the connections to the ESC. Check all with a Multimeter, if they make really contact.

Stupid me - now I know.... sure somewhere in the manuals or here in the thread, but me and manuals...

Walter

Mmmhh, Walter, I cannot confirm this!?
I get a connection to the box with plugged in the BESC and without powering up the BESC...
Of course, I get no connection to the BESC itself...

Yes, of course, but when powering the BESC afterwards and disconnecting, reconnecting, I still had those "no connection to ESC, check data and power connections".
But when powering the BESC before connecting to Robbe Box, everything was fine.

[4712]

, but when powering the BESC afterwards and disconnecting, reconnecting,

Do You mean: "but when powering the BESC afterwards, Reading and disconnecting, reconnecting"?
That would make sense...

You should click "Restart" or "Disconnect" before You remove the plug from the BESC.

I will do a more comfortable reconnection in the next update.

Donno what the reason was, but I had quite a lot of troubles with the tiny ESCs.
Especially in Supermicro 3.5 A the soldering pads for the signal wires are extremely weak and break out of the ESC easily (you can this do very easy when pulling or whatever a little bit on wire/plug).
Destroyed some of those tiny ESCs

Anyway, everything is ok now, flew right now my first 5 batteries with my double brushless Nano CPX and am quite happy.
But it was a hard way - for me especially the micro ESCs, those stupid soldering pads...
Now I am using epoxy on the soldering joints to secure the pads, seems to work.

Thanks, anyway, unbelievably cool stuff

Walter

Thanks Walter, I will answer here, because I guess Your last post should have gone here.
There is nothing to apologize, I'm happy for every hint, feature request and even more any bug message. It helps me a lot to find any issues in the application and to make improvements.
I've done already a fix up for the check of BESC connection - for next revision.

This was my problem. I had a short in my JST-SH connector.
Everything works fine now, Flashed to 9.2

Many thanks

Nice to read
Thanks for the info!
