it should be really easy – maybe you missed the part where you couple your smartphone with Max2Play? This must be done just once after you installed the Bluetooth plugin and before clicking the „install Bluetooth Streaming to Squeezebox Server“ at the bottom of the Bluetooth Plugin (this really needs to know your smartphone as otherwise it will not start streaming).
After this you should see the Bluetooth device in your LMS in favorites.
Errors may occure when:
– no space left on SD-Card when installing
– no Bluetooth Connection to your Smartphone (indicated as green)
Hope this helps – Stefan
