Comment 11 for bug 1494225

sorry not been able to set my phone up for logging at the moment - although reasonably technical and used to using the cli for out of the normal occasions, I don't go for the cli normally and prefer a gui, so just need to get my head around setting up.

Not sure if it helps, but I did notice though that for normal operation as long as you are slow in connecting everything then it does all seem to hang together. Here's what I do (to get it to work);
- have bluetooth switched on on the phone (with the pairing already completed)
- switch on the headset and wait for the bluetooth icon to go from a black background, to white and then back to black.
- wait 20-30 seconds (till I think it will have sorted itself out)
- press the button on the headset (the one that initiates a connection and is also used for answering and ending calls)
- wait till the bluetooth icon goes white and the bluetooth volume 'overlay' is shown - this can take 30-40 seconds

I can now make or receive calls and the sound/mic are passed to/from the headset correctly.

If I try to 'rush' this cycle or answer a call then switch on the headset, that's when the problem shows and I get connection to the headset to no sound to or from the headset or speakers/phone mic.
