Inquiry scans.
I have a Nokia 6310i mobile phone.
It has a bluetooth menu item that says: -
"Search for audio accessories"
If I activate this on the Nokia, it finds the Bluetooth headset.
In Bluez, in hcidump, I would expect to see these requests/responds between those two devices, but I see nothing.
If bluez never sees the Inquiry scan from the Nokia, how will bluez ever be able to respond?
Cheers
James

The Nokia is probably making its decision on the basis of the class-of-device field returned by a device inquiry.
I'm not sure if this is visible above the HCI level.

you will never see them, because this is the job of the link manager and not the HCI layer.

You don't need this information on the host stack side. The Bluetooth chip itself responds to it.
Regards
Marcel

You can't see inquiry scans with hcidump. Afaik there is no way to find out if your bluetooth adapter responded to an inquiry from another device. The nokia probably looks a the device class - which is returned as part of an inquiry result - of the bluetooth device to find out if it is a headset/handsfree or not, so it can single out the headsets without having to use SDP (which is visible in hcidump).
If you set the device class of your computer to 0x700408 for instance, the phone should recognize your computer as a handsfree. Problem is that most devices will place a headset icon next to your computers name in the device list now ;)
greetings
Fred
