Bluebus not switching off #164

Hi Ted,

I think I've found the root cause for my battery drainage. Bluebus isn't turning off.

Everything works fine expect the fact it will not switch off.

Tried FW 1.30 and 1.32 now.

Any thoughts?

Best regards, Tim

@dertimaushh ,

Are you sure? With the keys out of the ignition and the doors closed, the LED on the BlueBus should go out within three to five minutes.

dertimaushh commented 1 year ago

Yes, after some days of quiescent current measurement - I can confirm it's never turning off.

@dertimaushh

But is the LED going out? How much current is it pulling?

have you tried running the restore command? Auto off is controlled by a configuration byte.

The Led stays on all the time.

~ 0,02-0,03A

Havn't tried any commands yet. Updated the firmware yesterday - but nothing changed.

Now let's wait.

Success - restore solved the issue :-)

If that's the total current measured (which it looks to be with the negative disconnected ie not the BlueBus alone) with the car asleep 20mA-30mA is well within spec (<40mA). For reference mine sits at about 19-20mA (with a sleeping BlueBus)

Seems like you've fixed a problem still but you may still have battery issues.

It has dropped by ~ 0,03A.

With Bluebus "on" the car pulled 70mA - now its at 40mA.
