Hi Marcel,

I have some comments and questions:

1. Multiple bluetooth adapters
This is an old discussion but we didn't written it in a stone.
Do you plan support address multiple local adapter or not?
If yes, we have to plan how define the object path. My suggestion
is insert the device id in the path(org/bluez/dev_id/hci,
org/bluez/dev_id/pan, ...).

2. Non D-Bus systems
You wrote in an old email: "bluetoothd should combine hcid and sdpd".
I didn't understand the scope of this assertion. IMHO in the future
for D-Bus enable systems bluetoothd should provide hcid, sdpd and
profiles services(D-Bus).
hcid features include control initialize/register) adapters and
provide D-Bus services for get adapter infos and basic task like
inquiry, scan, remote name, ..
sdpd services include register/unregister local services, control
incomming connections and D-Bus services for search services.
Regarding sdp services, is it necessary provide a D-Bus service for
register/unregister services or we have to use sdp_connect +
sdp_device_record_register?

As long as I could understand, bluetoothd will not be only a
D-Bus service provider, but it must support NON D-Bus clients too.
Is that correct?

3. API version
We have to think how keep the backward compatibility among
the future BlueZ D-Bus services versions. I my opinion we have three
options:
- create a initialization service for bluetoothd where we
can check the version.
- insert an extra arguments in each method call(request)
- define different interface name based on the API version

4. Introspect
It's becomming common implement a Introspectable interface that
make possible get a xml string describing the provided services.
It can be a good feature support it.



Regards,
Claudio
