Hello, Thanks; apologies for the code - I was just trying to be explicit; other linux forums I've used before in the past have said that if I don't post the code they won't respond; I agree it is verbose! On the code you posted; I've studied it and to be honest - I can't see any difference between the code you've pasted and what the Python code is doing. The issue is that the C examples are quite different and this is what I've understood from the examples: - the OBEX one is registering a service record which goes back to where I first had a problem plus it is OBEX but the concept of listening for the bluetooth to come up and down is something I can make use of later - the ofono seems to make a simple registration (again similar to the python code) though the device_send_message is something interesting that I was going to come back to later - the pulseaudio one again sends a path and uuid followed by options but there is nothing I can see there that affects me. - the hfp example at https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/test/test-hfp is very useful as it gives guidance as to how to use the filedescriptor returned on newconnection but this goes counter to the send_device method on ofono which; if I am reading it correctly; seems a better way to send a message What is interesting in the C examples is that the calls are all async; maybe the python dbus library is not returning the calls correctly. Reading these examples is good and it really helps me understand items for the future. Right now the counterpart connecting to my device is a windows PC; I'm going to switch to a linux PC on the other side so I can get logging and try again - I'll also put the interrupt channel in to the connection and if that does not work then the control channel. I thought that this was defined in the profile as it was in the sdp_record so I didn't add it in. Thanks.
