Pixel 4 bluetooth connectivity issues

[stemo76]

Seems that my phone won't always connect on the first wake-up. Red light in top corner of the radio. Next time I start the car it connects.

Not sure if this is just a Pixel issue or if others experience this as well

What version of the firmware do you have? I had that problem with older versions but not with the latest versions.

This sounds more like the "cold BlueBus" issue than anything. Is it less than 60F where you are when the issue first happens? Some BlueBus units fail to boot all the way when they're cold. I can fix them by removing three small components and replacing them with a mod-board that changes the power supply sequencing for the BC127 BT module.

The way to know for sure if you have the issues:

1. Remove the unit from the car and place it in the freezer for 60+ minutes.
2. Remove the unit from the freezer and immediately plug it into the USB port of a computer, make sure NOT to unplug it.
3, Follow this guide: https://github.com/tedsalmon/BlueBus/wiki/Accessing-the-Terminal
4. Run these commands:
set log bt on
bt version
5. Post the results

Thanks! -Ted

My unit came with the 1.1.17 installed.

Yeah, that's failing to start when it's cold. Can you please shoot me an email at support@bluebus.dev and I'll give you my address so you can mail it in for service.

Thanks! -Ted
