Feel like a Staples ad, "That was Easy!"

Thanks Ted,

So, the app to flash the BB is very simple and fires right up without any installation to speak of. The flash it self was less than 5 minutes and the whole process took 10 minutes I think.

Plugged it back in the car and the settings were still there, just had to turn the phone pairing back on.

Since the two incidents with the LCM "hanging" were quite far apart in time, it will be difficult to know whether this fixed it. At least now my son knows what to do if it happens to him as he is the one who drives the X5 the most.

Unfortunately still have to hook up the BMW OEM microphone I installed..... I got a 6 pin pigtail off Ebay long ago but have sort out the pin-outs and wire it up.

It's more noticeable when I use voice commands with Siri. I'm not using DSP, my car doesn't have a subwoofer and stuff. I'm okay with the noise because the full integration is loads better than the FM transmitter I was using, but is this a thing I can fix?
Doesn't look like this was ever addressed? I wonder if others are experiencing the whine.

The A/C whine is definitely the exception and not the rule when it comes to the BlueBus. See, the core issue is that the rectifier diodes in the voltage regulator of your alternator are not fully rectifying the A/C into D/C voltage. That A/C voltage then leaks onto the D/C electrical system and is then picked up by the BlueBus. The reason the frequency (audible pitch) of the whine goes up with RPM is because the alternator spins faster with more RPM.

Most people don't have issues with the voltage regulator, so it's a non-issue. If you use the digital interface on the amp, it's also a non-issue because the whine isn't being converted into the digital signal sent to the amp (since it's 1s and 0s instead of an analog waveform).

In any case, if the afflicted user doesn't have the DSP amplifier to make use of the digital audio interface, then a ground loop isolator will remove the A/C whine. When it comes down to it, I sell a plug and play harness for a standard Amazon-special 3.5mm isolator.

With the 2.0 revision I wired things so that power and ground coming into the BlueBus *must* go through a common mode (A/C) choke with the hope of finally riding the circuit of any possible A/C whine.

-Ted

As Ted wrote above, he recommended the ground loop isolator and it resolved my issue. Everything is working great!

Same. The isolator Ted recommended and his cable worked for mine.

A quick update for the July 2022 batch: PCB assembly, programming and test is happening this week. It'll take them about a week to arrive, so I should be shipping late next week or early the following week. I'm hoping to get most of them shipped in a single day by taking time off my day job.

If you want to see "how BlueBus's are made", check out Instagram: https://www.instagram.com/bluebusbt/ -- Pictures and video are from yesterday (Australia time).

I'm STILL loving my BlueBus, but based on this or that, I'm still preferring to run 1.1.15 or 1.1.16 as it seems newer versions cause slight issues with my phone calls (ppl say they can't hear me as clearly/loudly) so I'm glad its an easy/quick process to load firmwares

Thanks for the updates.

just an FYI: firmware 1.3 was just released and has a bunch of new options in it for making calls louder, mic more sensitive, lower music volume automatically when reverse gear selected, etc... https://www.bluebus.dev/software
