If I understand correctly, every plugin like HFP, DUN, SAP will add status callback for different event. Exactly, that's the idea. > > > 3. plugin/dun.c prototype.

I am now making a prototype to create this atom in oFono. > The structure is similar to voicecall.c. An emulator manager could create HFP AG, DUN or SPP type emulators. When one is created, other atom get notified and register their interested AT command handers to GAtServer. So in this way, agent server on BlueZ may call oFono CreateEmulator method and pass file descriptor directly to oFono. If I understood correctly the Emulator will be useful for the DUN Gateway side.
