Hello,
Thanks; I followed Barry's example on making the device discoverable
via bluetoothd and that can now be found so the profile is registered
without needing the sdp_record. However the profile isn't getting
callbacks still except in one case where I kill the bluetoothd process
and the release method on the profile is called which is strange.
Looking at the output from dbus when a connection happens; we have
the following:

So there are events being fired just not the ones that connect to my
registered profile. In addition I've tried to register the profile
and listen for connections on the device PSM of 17 and 19 which HID
uses but nothing happens there either - though I'm not sure this is
the best way to communicate as it feels 'wrong' tbh.
Thanks again - I'm still basically not getting any events fired on
the profile except for Release which isn't really that useful as it
only notifies me if the bluetooth stack goes down!
Any ideas?
Cheers,
Neil
