Hello!
I'd like my FreeBSD computer to detect the presence of other
Bluetooth-devices nearby.
I have a little USB-dongle plugged into it, which is recognized as ubt0.
I started "hcidump -a" while turning Bluetooth on the iPhone next to the
dongle on and trying to link to a pair of BT-headphones. The "hcidump"
didn't print any traffic even though, of course, the phone did try to
radio out.
How can the detection be made to work? Note, I don't want to decode any
communications between BT-devices. I just want to detect their presence
and what information about them, that's not encrypted...
Thanks! Yours,
-mi
