[Bug] Bluetooth sleep/power states [answered]
asked 2014-01-08 15:30:50 +0300
I use the Jolla frequently in a car with a Pioneer DEH-6400BT radio/cd unit over bluetooth.
The problem is that no handshake takes place if the screen on the Jolla isn't displayed/active. Both devices are paired of course.
Works: [bluetooth on Jolla is active, hidden] Start car --> radio comes on --> double-tap Jolla to wake it up --> bluetooth handshake and connection takes place automatically and works well for the duration.
Does not work: [bluetooth on Jolla is active, hidden] Use Jolla --> when screen switches off --> start car --> no bluetooth handshake takes place........ever.
So, this seems to be a powersave bug since bluetooth handshake ONLY works when the Jolla screen is displayed/active. Please fix!

There is already a very similar thread covering most likely the same bug. https://together.jolla.com/question/868/media-player-trough-carkit-handsfreenot-working/

My article is specifically to the alertness of the bluetooth handshake service (works with the display active, does NOT when sleeping/display off).

Jan Wellmann ( 2014-01-09 07:44:18 +0300 )editGot you, we are in agreement then. I concur that this bug could be related in many other cases where bluetooth connections disconnect/reconnect. Here's hoping it will be fixed indeed.
