BlueBus: A fully integrated A2DP Bluetooth solution

[t3ddftw]

Just did the online update using my Mac to the latest Beta version and worked flawlessly. Thank you t3ddftw

The only thing is i cant see the Battery voltage option available for me to turn on. Any suggestions?

To close the loop here, the issue was that no light features were enabled, so the I/O status request message wasn't being sent, and battery voltage is read off the LSZ/LCM. I fixed this and it will be released with the next beta, although I need to make sure it doesn't start causing IHKA crashes again.

This is an awesome product. Definitely adding this to my newly acquired E46 M3.

Thanks!

I installed it the same way as you in the beginning but modified it to put it where the 6CD changer was.
The issue with where you mounted it is for updates it is a major PITA as you have to remove the carpet.
If you mount it where you have that tray, you just have to open the flap in the trunk, connect a USB cable, and update. Much more convenient.

I installed it the same way, but I plugged in a USB and fed it between the DVD and tray. Stashed the rest of the USB in the tray. For updates. Plugin, run the update then forget.

I like the TCU tray installation method; I would recommend a right angled USB Micro-B cable, or just install it with the USB port facing the front of the car, while in that tray

Did I read somewhere a CarPlay version will be released soon

Ted hinted something involving carplay on a social post. I don't think it's known exactly what it's supposed to be. However I think I speak for us all when I say we are all anxiously awaiting more info on that.

(Thank you Ted for blessing us all with the gift that is bluebus).

The hardware was done, but then Texas Instruments EOL'd the DIT4096, so I need to rework it. Some of the software is done as well. I am pushing to release a good stable BlueBus firmware with a ton of extra features and improvements before I move back to the CarPlay / Android Auto solution.

I just installed Bluebus in my '06 M3 Comp and its amazing (after having it for like a year and not installing it). Sound quality is great! Now I am eagerly awaiting the release of the CarPlay unit!!!! Reading this thread and watching the youtube videos of the install I was slightly confused about how to install it and what I could and couldn't leave unplugged so I thought I'd add some pics that will hopefully clear things up for people.

First picture is of what I think is a relatively unmolested area behind the trunk carpeting right as I pealed it back. The silver box on top is the telematics module for BMW assist that no longer works for an e46 and its my understanding that its just dead weight at this point. I removed it and have not noticed any issues with it being gone. The telematics module (at least on my car) had 3 connectors: the 54-pin connector on the backside (red arrow) that we are reusing for Bluebus, the black antenna hookup in the foreground, and the white/purple antenna hook up. We aren't using either antenna hook-up going forward. Of note, the telematics module weighs about 2 lbs so you get that weight savings. Also the black antenna is what connects to the sharkfin antenna on the roof, so if you are so inclined you can now remove the sharkfin antenna and the now unused cable to it for additional weight savings (it just adheres to the roof). Also note the bundle of unused connectors (other red arrow) tucked in the back. That bundle included only the 2 CD changer wires that we need for Bluebus and at least in my case was just wrapped in some foam take and stuffed in that back cavity in the quarterpanel behind the amp.

Second picture just shows the lay of the land with the telematics module removed and shows the 3 connectors we need relative to one another. It also shows that black unused antenna wire going to to the top of the rear quarter panel where it exits to then route behind the rear window trim to the sharkfin.

Last picture shows the Bluebus installed with factory hardware in place of the telematics module. Its a perfect fit. A little cable management and some felt take around the 54pin connector adapter to prevent rattles and its good to go. I hope that makes install a little clearer for some people. I counldn't be happier... well until the CarPlay module is released!

Messed around with it yesterday and saw the same. MacOS tool still works fine. I forget my bootloader version, but I have a very early unit, if that makes a difference.

I just fixed this. It was due to a *sarcastic gasp*, wait for it, off by one bug in early bootloader versions which included an uninitialized byte as part of the XOR checksum. I added a catch for it and now it works:

I’ve had some folks with bootloader 1.3 and 1.4 report this. I’ll be looking at it early next week

FYI, I rolled out the online releases portion of the new firmware tool, so you can keep up with and easily load the newest version right from the website.

I used your online tool to update mine, and it was a breeze, thank you very much for that new solution !

Woah, cool!

Can't wait to be flashing my BlueBus on the side of the road with my phone cause I wrote some dumb bug into the FW
