What would make most sense here? the basic concept behind ProfileManager API that we used for BR/EDR worked out pretty nicely. So maybe extend the general idea with the agent and callbacks to GattManager. When looking at the difference then we are talking about accessing remote GATT service via a local GATT profile. So what we want is implement that profile handling in an application. If we want to avoid overloading we could use GattProfileManager and GattProfile as terms to implement that. However the general idea that you get the connection status via the callback (in this case it would be an object path and not a fd of course) seem still valid. Especially with LE we have to handle the auto-connect cases gracefully. And if we have a connection oriented channel assigned with a GATT profile, then that could be just reported via an extra callback. In that case it would be exactly like we do within ProfileManager.
