@tmigone seems to work for me using a Pi 3. The only hiccup I encountered was that if the phone was playing audio when the device reconnects, the audio does move to the device but stutters and sometimes doesn't recover and drops the bluetooth connection.

If the phone is not playing audio when the reconnect happens it appears to all work OK.

@chrisys I believe that error is the infamous BT/WiFi chip interference. Or at least that one manifests itself with the same error codes. I've tested with my Pi3 and it did manifest one out of three times i tried, but then switching to usb bluetooth dongle seems to work 100%.
