Cannot connect bluetooth headset Bose Qiuetcomfort 2

Hi Coreelec team,

I am hoping you can help, i am using an amlogic device the MinixU1, working great except for the bluetooth.
I have the latest update 9.0.3
I see the headset mac address but cannot connect nor pair, sometimes it connect’s briefly then auto disconnects for some reason.
Here is my an extract of my kodi.log file:

2019-07-07 18:18:59.223 T:3724723056 ERROR: ## CoreELEC Addon ## bluetooth::dbus_error_handler ## ERROR: (Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.)
2019-07-07 18:18:59.223 T:3724723056

then a bit further in the log:

2019-07-07 18:19:08.159 T:3724723056 ERROR: ERROR:dbus.connection:Exception in handler for D-Bus signal:
