Bluetooth Audio lost

Dear Communauty,

First I take the chance, from Paris (france) to wish You all a great Year 2015 !

Now, my issue. Santa Claus brings me a wonderful Cambridge Audio Minx XI (Audio BT100)

When I paire with my MacBook Pro OS10.9.5, everything works fine.

But when I starts playing music from Itunes, after +/- 5min the bluetooth signal stops as sounds too.

Below the console messages :

I really don't understand what happens, and from which devise/ software the issue comes.

Indeed, As an alternative test case, I plugged my prievious HWS-BTA2W (Bluetooth AD2P connecter) on the Cambridge Audio Minx XI (analogic) and paired with the macBoock Pro. And I don't experience bluetooth lost !

I would really appreciate take the benefits of native connection between my MacBook Pro and the Minx Xi in order to get higher sound quality.

Thanks for your help.

Best regards,

Clémentine
