I must have damaged something on the car...
I don't know why I don't have call input audio anymore with genuine SES plugin as it used to work in my first tests before playing with wires...

Edit : It is not car but the bluebus...

I replugged genuine ULF bluetooth module with its SES jumper.
Call BT Audio and mic works with BMW ULF module.

So I probably damaged the bluebus with inverted pins on my first SES adapter build try...



Edit 2 : Neither my Windows laptop or my Ubuntu desktop are able to apply cvc with GUI tool, and neither of them can connect to flash firmware, it seems to reboot to bootloader and green led blinks... but not responding then...

Only screen / putty works for terminal log access.

[Orphee]

I have bt audio streaming working fine, I have music.

Issue only occurs in call.

Mic set to -23 yes.


Yesterday, before I played with rewiring, with SES jumper connected to SES connector (without any depin mod) , I had call audio working but no mic...
So like genuine, only 6 pin audio and 3 pin power connected to bluebus.

I don't know what I did...
Maybe a wrong terminal command while playing with terminal... ?


Today even if I plug everything like yesterday (genuine, no depin mod), no more call audio at all...

And when I plug the SES adapter I built to 6 pin bluebus, it does not work either ...

It used to work month ago before I sent back bluebus for repair with de-pin from SES connector to 6 depin connector...

I know I did a wrong wiring yesterday when I built my SES adapter...

I built it with pin 1 to 3 up, and 4 to 6 down, reversed form left to right...
Pin 1 and 3 was outside 6pins audio instead of near...

Did it damage something... Or is it only some miss programmation with terminal...
I only recall I sent cvc terminal command you gave me by mail...

I of course fixed my wirings and plugged back 1 and 3 to near 6-audio pin.

I also remind I had pin 19 from SES to 4 soldered instead of 18 at first...

Edit : when I make a call, the screen show "call" or sometime "voice assistant"

So it seems it detect the call...

When I hang up, the music starts again

[t3ddftw]

Thanks ! So in any case you have to depin or use an adapter linked to bluebus.

I probably damaged something on the car, I inverted some wires on the 6 depin...

I reppluged it all correctly but I don't have any call sound anymore...
No matter what...

I still have music, but even with ses jumper and nothing connected to the 6 depij bluebus, I don't have sound anymore...

I used to have at least remote correspondent voice working... But now nothing...
With it without the SES jumper and with our without home made SES to 6-depin connector...

So, to be clear, you have no inbound or outbound audio? This sounds more like a misconfiguration or license issue than anything…

Can you make sure the mic gain is set to -23dB?

Thanks!

Hi !

@t3ddftw I have a question regarding phone adapter.

Having the genuine SES jumper connected on SES connector does not make microphone works, does it ?

Does the 6 depin connector must be plugged to the bluebus ?

I have a SES jumper connected on SES blue 26 connector, but if I don't rewire the pins from it to the 6 depin plugged to bluebus, I can hear my friend (DSP with digital audio cable/mode enabled), but it seems mic is not working, he can't here me...

Do I miss something ?





Edit : I found https://www.bimmerfest.com/threads/s...stall.1307993/

And my SES jumper is correctly wired...

I will look at SES connector

Edit 2 : I double check my pins and all match. my SES jumper should be OK.

I suppose I must have an adapter cable from SES connector to 6 pin bluebus if I don't wan't to rewire manually, it is not just a matter of SES jumper... right ?

Thanks for the tip on pin 19!

Having the SES jumper should allow the microphone to work. Are you sure you've correctly de-pinned the 54-pin connector?

Do you own a multimeter to check for DC voltage at the mic connector?

Thanks!

t3ddftw A friend of mine would like to buy a bluebus soon.

He (almost) have an M5 E39 from 09/1999 with DSP.

Is DSP coaxial cable sold with bluebus does he have to request / add it in the shopping cart ? is the 6 pin connector for TCU phone included ?

Thank you

Edit :
May I also suggest to add SES pin connectors option in TCU de-pinning guide ?

Hi again !

It seems there is a mistake on the wiki, the TEL ON PIN is written as 19 on wiki for SES connector, shouldn't it be 18 ?

Yes, but this issue is complex.

The PDC "active" message is still broadcasting for some time after reverse gear is disengaged. Therefore, it's re-engaging the functionality.

Does your vehicle have a manual or auto trans?

I am under the impression that manuals can't broadcast reverse gear on the I-Bus, so if I took the trigger for PDC messages out and based it solely on gear selection, I may break this for manual transmission users...

-Ted

It is actually expected.
It is manual transmission.
But as I have front PDC too, it will stay on for maneuvers, to warn about any obstacle frontside.
It will not disable itself unless I disable it by clicking on PDC button, or by raising speed to like more than 20km/h forward.

It works perfectly fine when you engage the rear gear, the sound raise down and stay down, but when you switch back to neutral, I bet on cars than only have rear PDC, it is then automaticaly disabled once rear gear is disengaged.
As on a front/rear PDC cars, the PDC stays active even when you remove the rear gear, I suppose currently bluebus don't know how to handle this behavior.

The PDC "active" message will broadcast forever once reverse has been engaged, even when removed until car has moved forward fast enough to disable PDC. is it totally expected with cars with front PDC.

[t3ddftw]

How can I help with this matter ?
Did you receive my logs ?

I have not gotten a chance to look at the PDC issue -- I honestly forgot since I don't have a car with PDC

Hi There - Quick question, any chance we can get ibusapp to integrated with bluebus? I love the concept of bluebus and think it’s awesome as ive been following it since its inception!

Don’t android units have Bluetooth?

Unfortunately, you’d have to ask the IBUSApp guys about this, but the real issue is how you’re going to get the BlueBus audio output into the aftermarket radio :/.

I don't sell the coaxial DSP cable, but if the car was not equipped with the CD Changer pre-wiring I can definitely make the analog wiring required.

The 6-pin de-pin connector is available at checkout, free of charge

Thanks!

Adam,

The Blue connector pictured is the SES connector. Here are the pin arrangement from it to the BlueBus:

Pin 1 is the top row, lowest pin (closets to the 6 Pin Audio)
Pin 4 is the bottom row, lowest pin (closets to the 6 Pin Audio) right under pin 1
BlueBus 1 - Mute - SES 22
BlueBus 2 - Mic Neg - SES 8
BlueBus 3 - Spkr Neg - SES 12
BlueBus 4 - Tel ON - SES 18
BlueBus 5 - Mic Pos - SES 9
BlueBus 6 - Spkr Pos - SES 13

P.S. does the 6 pin connector going into the BlueBus have 3 or 5 wires in your car?

Thanks!
-Ted

[t3ddftw]

Ah, I did not expect so much work to be done...
In this case I will send it back to you then... if you are still OK

Of course! Shoot me an email so I can confirm the shipping address -- [email protected]
