Issues with Python Bluetooth sockets

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 to roll! (libpulsecommon-12.0.so(pa_log_levelv_meta+0x8b7) [0x7f915c40cf67])                                                

320 E: [bluetooth] module-bluez5-device.c: Failed to write data to SCO socket: Transport endpoint is not connected (libpulsecommon-12.0.so(pa_log_levelv_meta+0x8b7) [0x7f915c40cf67])

or

when my program is stuck in socket.connect()

 

I have also tried to use a BluetoothSocket from PyBluez with similar results.

Can someone please help me to set the socket up properly?
