When connecting with a new device via the NewConnection DBus method, we get a file descriptor to work with. I am fairly confused on what state this file descriptor is in, and what I need to do in order to read/write from it. Simply calling read/write does not behave as expected for me. > > In the file test/test-profile, I see this line of python code: > > self.fd = fd.take() > > I am struggling to find the Linux C equivalent to the take method, as I believe this is what I need to do to operate on the fd. Any advice on how to configure this fd in Linux C code so I can read/write with the fd would be very helpful! Though the code bellow is not handling the NewConnection it should give you clear picture how to deal with file descriptors: https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/client/gatt.c#n750 Or in case of actual NewConnection you can check how PulseAudio implements it for HSP: https://github.com/pulseaudio/pulseaudio/blob/master/src/modules/bluetooth/backend-native.c#L492 > Thanks > Austin > This e-mail transmission, and any documents, files or previous e-mail messages attached to it, may contain confidential information.
