BlueBus: A fully integrated A2DP Bluetooth solution

Is there any update on a new batch?

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).

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?

Thanks!

Thank you Ted

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.

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.

Actually the Kombi light is not full on, but only stuck at current dimm wheel setting level.
Disabling park lights in confort menu and waiting a few secs unlock the wheel settings. Then you can switch back park light ON.

Until next car start.

Okay, yeah that makes sense. The LSZ does not accept dimmer wheel updates while a diagnostic function is in process, meaning it will only update the dimmer setting once the diagnostic is over. The problem is that I am keeping diagnostics on indefinitely, so it never updates. One of my amazing project contributors was going to look into this, but I'm not really sure there's anything we can do.

That's why I'm wondering if the Intravee somehow solved this.

Thanks!

Tested with intravee, no issues with it!

We've identified what is likely causing this. The comfort parking lights automatically disable when lights are turned on via the switch (as they are redundant at that point), however this is delayed by up to 18 seconds. In this time the dimmer switch is apparently ineffective.

Hello,
I have a bug with latest FW, I guess it us linked to DRL :

Dashboard KOMBI light is full ON and the dimm wheel does not work.

And I don't know how I triggered it but I was able to get back light OK.

But it seems to happen every time I use the car.

I didn't take time yet to catch when and how it happens.

I have the same issue since i updated to 1.1.18. First I thought my LSZ is defect. Good to know that i am not alone.with this problem.

[Pklauser]

Ted, this is awesome, reminds me a lot of what the guys over at https://cantalouperadio.com/collections/products were doing, and as a software engineer myself I definitely appreciate the open source aspect!

If you still own the Intravee, can you check if this happens as well? It's a byproduct of keeping light diagnostics active indefinitely (DRL always on).

-Ted

I played a bit with it.
As soon as park light is on when I switch on headlights : KOMBI full ON

No matter I switch headlight OFF/ON, KOMBI full ON.

Now if I disable/enable parklight setting while headlight ON, after one or more tries, KOMBI light switch to real value and dimm wheel works.

I'll check with Intravee currently installed on the M5, but I don't recall having this issue with it.

Thanks

Weird -- Sounds like it has crashed and restarted. Did this correlate with anything happening, like a song change or a call coming in?

If you could, try to pull the trap counters via the terminals -- the command is: get err

Thanks!
-Ted

I've experienced a similar issue as Der_Spanier. This is with version 1.1.18 on an '05 M3 with a CD53. The trap counters show a non-zero BC127 Boot Failures value. I don't remember the exact number... I think it was 6 or 7, but it could definitely correlate to the number of "reboots" I've experienced.

I just thought it was the cold boot issue. I seem to remember that being a thing. The car stays in a non-climate controlled garage and it's been chilly here lately...
