BlueBus: A fully integrated A2DP Bluetooth solution

[t3ddftw]

Hello, is there any changelog somewere to see FW fixes and evolutions ?

Thank you

Edit : music count time is possible ? From beginning and/or from ending via a setting ?

GitHub is your best bet -- here's the commit log for 1.1.14 (which encompasses .12, .13):

[IMP] application: Version 1.1.14
* Shutdown all unused I/O ports
* Rename I/O Port defines so they are consistent
* Ignore values for coolant temperature that are outside of usual ranges
* Resolve issue with radio overlay button in BMBT UI causing the UI to jump back to overlay mode even when on OBC / Nav
* Add support for extended ASCII characters, since most BMW UIs support this encoding
* Resolve issue with BlueBus keeping vehicles awake via TEL ON by shutting it down when the ignition is turned off
* Resolve issue with BlueBus waking other modules up by pulling the I-Bus low just prior to sleep

On music count time, I'm a bit opposed to this as I find it to be frivolous information, but beyond that, while it's possible to implement, I couldn't do it correctly. The issue is that the BC127 doesn't provide any notification updates if the user skips playback on the phone (using the slider). This would lead to an inconsistent state between playback and where BlueBus reports playback to be.

I struggle to hear anything from a caller when I boost the mic gain. I have a CD53 and for a caller to comfortably hear me, I set the mic gain to C9 through the putty interface. That makes it nearly inaudible for me hearing a caller. Lower gain helps me to hear but of course hurts for the caller. Is this just me or is there another setting I haven't seen?

Are you planning to add the settings to the non nav radio interfaces like you did for the nav units?

Edit:
I'm stupid. Call volume isn't affected by the steering wheel controls with my CD53. Have to use the radio knob. Also C9 is too high with my 338 mic, which resulted in feedback. C6 seemed like the sweet spot for me.

Ted,
How do you get the firmware file 1.14? I went to github and it is not clear were to get the file. If you could provide a place/link/instructions on where/how to get the latest production firmware, that would be great.
Thanks

Adam, link to the latest firmware file is at the bottom of Ted's post dated 7/4/2020 @ 5:30 PM PT.

Ted, thanks for the update dealing with power drain. Have updated to 1.14.

Can you shoot me an email at support@bluebus.dev? This sounds a bit too complicated to troubleshoot over the forum. I've also never had another user with the issue you've described, but a few users have described inbound caller distortion when using mic gain c0.

I do plan to bring over the fancy settings menu from the Nav UI to the MID and the CD53, just haven't found the time for that. Hopefully soon!

I will make a mailing list for these at some point in the future.

Thanks!

You may create a simlink to "latest" zip (file + version txt) that we could bookmark ?

Maybe if I stopped hosting them on AWS :P

I have thought about other creative means of notifying users -- I'll come up with something.

Hey guys,

I have some unfortunate news for everyone in the first batch who ordered in December:

I've recently figured out, after a few units turned up with similar failures, that a specific part (P-Channel MOSFET "Q2", for those curious) is failing pretty consistently due to it being under-rated for the voltage it's carrying.

The result is that this part is going to fail at some point, and may or maybe not take other components on the BlueBus out.

This is 100% my fault as I glanced by the value on the datasheet when originally shopping for a suitable part.

As I stand behind the BlueBus, I am going to be recalling every unit and I'm going to replace the part with one properly rated for the job.

If you are part of the second batch of BlueBus units, this DOES NOT impact you as I was able to have the correct part installed prior to assembly.

Q / A

How do I know if my unit is affected?
=====================================
If you ordered in December, your unit is affected.

When will my unit fail?
=======================
At some point in the future. It's hard to tell, and I've only had 12 failures attributed to this part.

What happens if other parts, or the whole unit fails before you recall my unit?
================================================== =============================
All impacted parts will be replaced and you will be given a fully working BlueBus.

How will you handle recalls?
============================
I will soon be emailing users in groups of 50 to send their BlueBus units in. Units that have been in use longest will get priority, as they have a greater chance of failure. If your unit fails while you're waiting, I will immediately have you send the unit to me for repair. You will have 4 weeks to get your unit shipped to me, after that any failures will NOT be covered by me, and I will charge you for the part required to fix the unit.

Why did this occur?
===================
Reading is hard, apparently.

Is anything else on the BlueBus going to fail?
==============================================
Not likely! I've gone over the datasheets, typical application schematics and recommended layout guidelines for all parts on the BlueBus and everything else is fine.

What if I'm not in the U.S.?
============================
Users in the EU/GB will send their units to a gentleman I know and trust in Germany who will perform the repair.
Users elsewhere will have their units swapped out with one of my spares.

Let me know if you have any additional questions and please know I am so sorry about this issue!

Please refrain from emailing me with regards to this issue unless your unit has failed as I'm the only person who fields questions.

Thanks!

That's a bummer but growing pains are pretty common with a new product. Thanks for the head's up. Should we remove the Bluebus from our cars in the meantime?

Also, for anyone who struggled to remember when they ordered, I was able to pinpoint it by looking at my PayPal history.

Bad news !
Happens, i'm probably on the list then...

I guess I can be more clear: If you have a BlueBus in your hands right now, you're impacted . I have "batch 2" sitting in my house right now.

Thanks for your understanding! I wouldn't remove the BlueBus from the car unless you don't drive the car very often. I'm not going to make you guys suffer without a unit because of this, so I'll just deal with collateral damage if it happens. Thankfully, the failure rate is pretty low.

Unfortunately! But the unit you're getting in the mail soon (hopefully!) is not, so that's a plus.

Thanks!

Thanks for being so upfront and transparent about it. You really are good dude standing behind your product. I'll wait for the mail and instructions Doesn't change how satisfied I am of the product though!

Thanks, I appreciate that! No way I was going to let them burn up after all the time, love and energy I've put into this thing.

No worries kind sir, thank you for standing behind your product!

Hey guys,

If you are in the U.S., recall instructions are in your email.

Thanks!
