[SOLVED] problem with bluetooth - pair but doesn't connect

[georgew21]

On my old phone, I would find that moOde would sometimes not appear as an audio device.  I found that removing all trace of the pairing on the phone then rebooting everything (phone and moOde) would clear things up so it appeared properly
again.

after the new clean image I used, I tried new devices but I had the same result. 
I tried to make the conenction by ssh following this guide

The problem is that I never see the authorization for a2dp service after the confirmation of pair:

Code:

pi@moode:~ $ sudo bluetoothctl
