BlueBus: A fully integrated A2DP Bluetooth solution

[Der_Spanier]

Can you guys try this firmware? https://t3ddftw.s3.us-east-2.amazona..._1_19_rc_4.hex

A Russian customer recently sent over a log that shed some light on the issue -- the CD53 fallback code was registering/deregistering its event listeners a every 20 seconds or so, which eventually hit a wall in the size of the event listener array and led to a call to a function existing outside of memory bounds. I resolved this and it seems to have stabilized the UI.

I'll give the new firmware a go.

The funny thing is, since the last time we spoke, when I said the BB crashed pretty much every time I drove the car, it's barely happened again. It happened once or twice in december and it's been completely fine ever since. And I've done absolutely nothing to the car in that time... Btw, I apologise for not saying this earlier. Life's been a little crazy lately.

I'll report back once I have version 1.1.19 running.

I have not had the time to plug my laptop in yet, but things have definitely gotten worse.

Now it seems to happen pretty much every time I use the car and stream music through the Bluebus. It takes 30 secs to a minute from when I switch to Bluebus mode before it resets itself. After that everything is fine for the rest of the journey. 100% does not coincide with a song switch or any particular event.

The only thing I've observed is that it's got worse as temperatures have properly dropped here.

Having the same problem here occasionally, I might roll to a different software version as it didn't do it before unless it was something related to the cold weather fix

May, not March :|. Sorry!



That's nuts. My E46 M3 does not report reverse gear being engaged on the I/K-Bus.

This is a feature that for not will not work on the newer BlueBus. For whatever reason, I cannot get Absolute Volume controls to work on iOS or Android.

-Ted

I was not expecting it to work at all, but engage reverse and pow, the volume lowers... I am leaving it on as I find it useful.

[t3ddftw]

Sounds good! I've had an order with ECS since September of last year, just wanted to get a real eta as they had no clue. I dont mind waiting until March for a product like this!

I updated my unit on my Z4M, which has no rear park sensors, but never the less the lower volume feature works, which I find cool as it allows to focus on the maneuver.

all I need now for it to be prefect is to unlock the hatch with the comfort unlock feature, right now it only unlocks the doors and fuel filler cap

Well, I'm working on the new hardware. The software side is fairly stable, and I have secured 500 BM83 Bluetooth modules (the new BT module), which are hanging out in my closet right now until it's time for manufacturing.

I should have a beta version of the new hardware ready next month, and the rest of the bits and bobs that I need to make the unit will be available towards the end of March. That means they should be shipping around late May.

Most of the parts I need will once again be available near August of 2022, so I'll probably do another run of units then.

Keep in mind that the electronics supply chain is not back to pre-COVID days, but it's definitely better (for now).

I think I might have made some headway into this issue, but I cannot replicate it to save my life. If anyone is willing to try a beta firmware, shoot me an email -- [email protected]

Thanks!

You're unfortunately still the only one reporting this, and the temperature wouldn't impact its ability to stay running once it's already streaming and connected . Any chance of getting a log now that it's so easy to reproduce?

Is there any update on a new batch?

Yes can you please post a link to the latest firmware? I just got my car back so want to update it please

Just enable IBus logging for a quick second and note the number between brackets. For example,

[2729302] DEBUG: BM83: TX: AA 00 02 14 1A D0

2729302 / 1000 = 2729 seconds of uptime, or 45.48 minutes.

Looking at the module you're using, it looks like it could support aptX-HD if loaded with the right firmware, is that correct? Curious if the bluebus as-sold supports that codec.

You'd have to load the -HD firmware and get an aptX license (good luck), then enable it in Melody. It's really not worth the effort, but it's possible. FWIW, I did test aptX way back with the prototypes as it was enabled along with CVC with the demo license.
