BlueBus: A fully integrated A2DP Bluetooth solution

[duperdog]

Neither of my E46s have this problem. Are you familiar with the steps to ensure the BlueBus is sleeping?

Thanks!

I'm having the same issue and am not aware of the steps to ensure it's sleeping.

Has anyone had any issue with a parasitic draw with the 2nd version? I have the first version it my car and it’s fine. My dad has the 2nd, in an all stock (he is original owner) e46. Ever since he installed it it has been draining his battery and it killed the battery over the winter. He didn’t drive the car for a week last week and his new battery was completely dead.

I do not have that parasitic draw issue with my “V2” hardware.

No real idea. I have a 1.3.3 build available if you want to email me, but there are a huge amount of features that are pending merge back into the mainline codebase. I just haven't found the time to clean the code up and test it all.

-Ted

Fair enough! Take your time, I have a 1.2k mile trip planned for this weekend, and I need the BlueBus to work properly… I can play beta tester once I’m back from my holidays

Thank you once again for the great product you’ve created!

Looking forward to finished version my friend.

HI Ted t3ddftw, just wondering when you'll be releasing the next firmware version? Should be 1.3.3 if I'm not mistaken.

Many thanks!!

Hi t3ddftw Ted. Other callers say I sound "tinny," not that they hear themselves at setting 0. Just asking for a good default number suggestion. Mic is original OEM. Thanks.

Sorry for the lag getting back to you on this! Try 3dB, then go from there. You might need a tiny amount of gain to let callers hear you.

Thanks!

t3ddftw - quick question. The GitHub Wiki page says a good default setting for Mic Gain is -23. My Bluebus won't set that number any lower than 0. Can you advise? Thanks.

Howdy!

0dB is the lowest on the HW 2.x BlueBus. I assume the other party is hearing themselves? If so, what mic gain is it set to now, and what are the last three digits of the microphone in use?

Just added the ground loop isolator to my car like Ted suggested. What a difference! Very happy with how it turned out. Thanks Ted!

Here's details on how I did it in case anyone wants to replicate: https://nam3forum.com/forums/forum/m...ge8#post210857

Glad you were able to get it made, and thanks for documenting it!

Hi Ted,

I have the bluebus since day one and really loving it! Never thought the audio quality could be so good with my low-end (basic) stock radio!

I also have a pretty noticable alternator whine sound coming through the speakers, related to the rpm. When the radio is turned off, the sound is gone.

Can a ground loop isolator help reduces this issue? If so, can you share a wire diagram where to place the isolator? I have a MID radio, non DSP (unfortunately) and non amp.

Also, I missed the recall action for the early v1 batch, related to the handsfree calling? How serious is the issue, do I risk the bluebus will stop working?

Kind regards,

Jeroen

Yeah, the isolator would very likely resolve your alternator whine.

I don't have a diagram for how it incorporates, but it's pretty simple -- the goal is to wire this: https://www.amazon.com/dp/B0171PQLB8/ inline with the 6-pin audio output connector from the BlueBus to the car. I sell adapters for this which convert the 6-pin to 3.5mm and back, making it plug and play.

Yeah, your BlueBus could just stop working one day. You should really send it in, but you'll have to send it to the U.S. at this point. Shoot me an email, please!

Thanks!
