The PanoramaApp application allow you to control your Merlin head with your android device using bluetooth. Of course you have to plug a bluethoot connector on the head (like you do to use the Papywizard application for example)

This is the sample application given by the Skywatcher API project.

I did not write the code, i did just modify it in the connection code section to avoid the hanging of the application.
