The DBus communication is working and I can pass a file descriptor to pulseaudio as return value of "Acquire".<o:p></o:p> But I still have some issues with the setup of the bluetooth socket.<o:p></o:p> <o:p> </o:p> I create the socket like:<o:p></o:p> self.soc = socket.socket(socket.AF_BLUETOOTH,<o:p></o:p> socket.SOCK_SEQPACKET | socket.SOCK_CLOEXEC | socket.SOCK_NONBLOCK,<o:p></o:p> socket.BTPROTO_SCO) #These params are taken from ofono<o:p></o:p> self.soc.bind(self.address)<o:p></o:p> fd = self.soc.fileno() #fd will be sent to Pulseaudio<o:p></o:p> <o:p> </o:p> But then calling accept() or connect() on the socket (in my script) will result in an Error.<o:p></o:p> Only when i don't set the socket to non-blocking, connect() does not throw an error, but it blocks endlessly.<o:p></o:p> <o:p> </o:p> From Pulseaudio I the following Log messages:<o:p></o:p> <o:p> </o:p> without calling connect():<o:p></o:p> 319 D: [bluetooth] module-bluez5-device.c: Stream properly set up, we're ready to roll!
