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

I have also tried to use a BluetoothSocket from PyBluez with similar results.
Can someone please help me to set the socket up properly?
