Reiner,
Thanks for the "xhost +" suggestion - unfortunately it didn't help...
I pasted some details below in case it helps somebody suggest where I
might be going wrong.
Regards
John
Case 1 - hcid.conf/security = user: Whether I use my phone or bt
headset, with bluez-utils 3.9, hcid just sits there waiting for a pin
pop-up that doesn't happen. I had this problem with bluez-utils 2.15
but at least I could set a pin-helper to fashion a work-around.
# hcid -n [security=user - pin request via hcitool cc/auth
00:0A:D9:E8:4A:65, xhost +]
hcid[2745]: Bluetooth HCI daemon
hcid[2745]: HCI dev 0 registered
hcid[2745]: HCI dev 0 already up
hcid[2745]: Device hci0 has been added
hcid[2745]: Starting security manager 0
hcid[2745]: Device hci0 has been activated
hcid[2745]: link_key_request (sba=00:10:C6:56:F4:9F, dba=00:0A:D9:E8:4A:65)
hcid[2745]: pin_code_request (sba=00:10:C6:56:F4:9F, dba=00:0A:D9:E8:4A:65)
[then nothing]
Case 2 - hcid.conf/security = auto: I can initiate a connection with
my phone and pair my machine using the local pin in hcid.conf. Maybe
I'm missing the logic here, but when my bt headset is put into
pairing mode, shouldn't hcid recognise this and use the local pin in
hcid? In practise, hcid sits there waiting for me to enter a pin on
the bt headset which of course is not possible.
# hcid -n [security=auto, connection from phone]
hcid[2776]: Bluetooth HCI daemon
hcid[2776]: HCI dev 0 registered
hcid[2776]: HCI dev 0 already up
hcid[2776]: Device hci0 has been added
hcid[2776]: Starting security manager 0
hcid[2776]: Device hci0 has been activated
hcid[2776]: pin_code_request (sba=00:10:C6:56:F4:9F, dba=00:0A:D9:E8:4A:65)
hcid[2776]: link_key_notify (sba=00:10:C6:56:F4:9F, dba=00:0A:D9:E8:4A:65)
[paired OK]
# hcid -n [security=auto, headset in pairing mode]
hcid[7423]: Bluetooth HCI daemon
hcid[7423]: HCI dev 0 registered
hcid[7423]: HCI dev 0 already up
hcid[7423]: Device hci0 has been added
hcid[7423]: Starting security manager 0
hcid[7423]: Device hci0 has been activated
nothing happens, so then
# hcitool cc 00:12:EE:A6:1D:F4
# hcitool auth 00:12:EE:A6:1D:F4
HCI authentication request failed: Input/output error
hcid[7423]: link_key_request (sba=00:10:C6:56:F4:9F, dba=00:12:EE:A6:1D:F4)
hcid[7423]: pin_code_request (sba=00:10:C6:56:F4:9F, dba=00:12:EE:A6:1D:F4)
One thing I noticed with plugz and bluez-utils 2.15 is that when I
try to play music to the headset, it automatically pairs (via the
pin-helper I presume) but no music appears due to the sco buffers problem.
# mplayer -ao alsa:device=headset /.../music.mp3

When I try this with plugz and bluez-utils 3.9, the initial
connection is rejected but this is not echoed by hcid...
