Re: Registering a profile

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

 



Hello,

  I've been running a dbus-monitor and I can't see the interface being
called of 'org.bluez.Profile1' - I can see 'org.bluez.Device1' and
I've tried listening to that interface and also on the path with
dev_<ADAPTER-MAC> but I'm clearly doing something fundamentally wrong.
IF anyone has any advance I'd be very grateful and there is 100 rep
points up on Stack Overflow for any advice too!

  Thanks; it's late here and I'll not be home till gone 1am so I'll be off now!

Cheers,

Neil
