HI Markus,
No i did not getting any respone, also not on the Philips Forum. unfortunately.
I have no experience building a binding so can’t help you.
What i notice if a use the default google anymote app on android that when i try to connect for the first time the tv displays a code (4 digits) that i need to enter in de anymote app. Maybe that your problem.
I can test and look at your binding if you send it to me.
