BlueBus: A fully integrated A2DP Bluetooth solution

[t3ddftw]

t3ddftw Any more information on the Ground loop isolator? For me the alternator whine is most annoying when the radio is off completely. Are the 6pin to 3.5mm adapters just wire adapters or is there more logic to it?

If the radio is fully off (via the knob), you really shouldn't be hearing A/C whine

It's just a simple wire adapter.

I buy these: https://www.adafruit.com/product/1700

Then I crimp on these terminals from TE connectivity:
1355719-1
1355717-1

Finally, I assemble the connector ends with these parts (also from TE):
1379118-1 (Vehicle end of the connector, which needs to have both ground pins populated)

185311-1 (Inner Terminals Housing)
953382-1 (Outer Housing)
953381-1 (Inner Housing locking cover)

Thanks!

I definitely wouldn't activate the low beams in any case, haha.

For "Follow Me Home", lots of folks want the high beams on so they can illuminate their walkway. For Welcome Home, perhaps high beams don't make as much sense because you may not be aware of what's in the path of your light beam.

Hey Ted, i think with the flog Lights you can also illuminate their way. I also doesn‘t like the high beams idea, i’m also agree the dazzle argument from der_spanier. If the cornering lights were also on isnt relevant for me.

Yeah, that's true. My first M3 had them wired to the interior lamps, so they turned on when you unlocked the car, which was neat.

Thats a really cool wirering idea!

Xenons don't like being switched on and off too often, or at least that's what the owner manuals for both my E46 and E39 say. For this reason I'd keep the low beams off.

I wouldn't activate the high beams either: depending on where the car is parked, it could dazzle other road users.

Therefore I think the best compromise for the front would be the fog lights. Possibly corner lights too (could look good on facelift E39s and E53s, not too sure about the other cars not having angel eyes). At the back I'd switch the rear tail lights on.

Same pattern for "Welcome Home" and "Follow Me Home", I think. Or is there a reason the patterns should be different?

I think corner lights would be best bet as a lot of people have angle eyes wired into their corner lights aswell.

High beams in both cases or even xenon's but only if they aren't a bigger power draw

[t3ddftw]

So I'm prepping firmware 1.3.2 for release and I wanted to add a juicy feature to get folks to upgrade (so they can take advantage of all the bugfixes). I'm thinking that this is going to be "Welcome Home" and "Follow Me Home" lights, which people are always asking for.

I wanted to get some input from the community about what lamps each feature should trigger (and no, I'm not making this configurable -- that's a LOT more work).

Follow Me Home:
Fog Lamps
High beams

Welcome Home:
Front Corner Lights (Angel Eyes on the applicable E39s)
Rear Tail Lights
And possibly: High Beams

What are everyone's thoughts?

Hello party people, while waiting for my second Bluebus to go into production I thought if its possible to rename the Bluebus' BT name.

Also since here are a lot of skilled engineers, do you know a way to integrate DAB+ into the factory navigation/audio system?

The 1.x units (which are identified by the green LED) can have their names changed via the terminal. 2.x units require you to recode the Bluetooth module, which I haven't documented yet.

I got nothing on DAB. We don't use that here in the U.S. so I've never looked into it.

Thanks!

I believe the name can be changed by accessing the terminal: https://github.com/tedsalmon/BlueBus...g-the-Terminal

As far as DAB+ is concerned, no idea if that's possible. However, I don't really see the point knowing the Bluebus allows you to stream whichever radio station you like from anywhere. Of course it uses mobile data, but nowadays most data allowance plans make this possible without any issues.

Is anyone else having feedback loop issues? I got a new Bluebus hw1.3 installed in a UK 2003 e46. I get an alternator whine but it's bearable, but in trying to record this I noticed that even with the engine Off I can hear things through my speaker. In the video below you can hear i think the fuel pump coming through the speakers? How could that be if everything is DC before the engine is running?

Alternator whine can be fixed with a ground loop isolator.

I have no idea what's causing the interference in your video. It could be the fuel pump, but I can tell you the same does not happen in my own E46s. What's your battery voltage with the engine off? Perhaps it's near the end of life and the fuel pump is demanding more amperage than the battery wants to comfortably provide.

I’m getting it in my 2002 325i sedan

What does your noise sound like? Does it follow RPM?

It's probably best for you both to email me at [email protected]

Thanks!

Ted any 54 pin adapters available?
