Ofono and BT interaction

Ofono and BT interaction

[Berthier, Emmanuel]

[-- Attachment #1: Type: text/plain, Size: 1014 bytes --]

After pairing a Handset BT device with my Meego Handset board, ofono sees a new modem called /hfp/XXXXXX and can start a voice call on it.

It is an interesting feature from a Netbook perspective, but could be very confusing from a Handset perspective.



I would prefer to remove BT devices from ofono modem list.



What's the best solution?

- disable BT modem client profile?

- disable ofono HFP modem support?

Emmanuel.

Would filtering by Modem type be enough? E.g. oFono could expose a
string Type property on the Modem Interface.  Possible values might be
'gsm', 'cdma', 'hfp', etc.

Hi Denis,

It's a good solution for ofono clients, but ofono will still dialogue with BT Modem (init), which is not very desirable.

If you power on the HFP modem. If not, then oFono will do nothing. You
can always start ofonod with -P hfp and then the HFP support should be
ignored. At least that works for testing.

Oops, sorry for that.

Yes, that's one solution. How to do that at BlueZ level?

Very interesting.
I've not found "-P" option in ofono 0.25, nor in the last 0.28 source tree.
Did I miss something?

no idea actually.

No you didn't. It is a ConnMan feature that we never ported over to
oFono. Not a big deal to add, but so far nobody did the work.

So, the question is still open:
How can I cut the link between ofono and BlueZ?

I still don't understand what you're trying to accomplish.  If you don't
want to establish an HFP connections, simply don't
Modem.SetProperty("Powered", True).  Or is your issue that ConnMan
automatically powers on the HFP devices?

If you don't want HFP modems to even be seen, disable the hfp plugin.
