everything looks good from the log you posted. Your Squeezebox Server is running on the same device, right? Did you click the “Install Squeezebox Server Streaming” after the pairing of your Smartphone was successful (this will add the Bluetooth Device to Favorites)?
One more Point: please enable the Autostart in the Squeezebox Server Bluetooth Streaming Options at the bottom of the Bluetooth page. With this enabled you don’t even need to do anything in your Squeezebox Server and Bluetooth will stream automatically once your Smartphone starts playing.
