[Bluez-devel] pairing problem

[Charles Majola]

Hi,

I have a strange problem. For some reason when I boot my pc, I can't 
make outgoing connections from my computer to my cellphone until I 
restart bluez services(although already started at boot time, incomming 
connections work fine). If I restart my computer, I have to restart 
bluez services again so that outgoing connections work. I can't see 
anything might cause this, it used to work fine with bluez-{utils,libs}< 
2.20. Any ideas ?

install the latest bluez-utils-2.21 and try again. Run "hcidump -X -V"
to see what is going on.

looks like your PIN helper is not working. Check the syslog for messages
from hcid.

Sep 30 10:03:09 localhost hcid[6848]: pin_code_request 
(sba=00:0E:A1:04:E6:C8, dba=00:0E:6D:45:2E:4D)
Sep 30 10:03:09 localhost hcid[7340]: PIN helper exited abnormally with 
code 256

It works fine once I restart hcid. Thats why I have no idea whats 
causing it.

the /etc/bluetooth/pin is only used for incoming connection. For
outgoing connections the /var/lib/bluetooth/<bdaddr>/pincodes can be
used. Look at the source code for details, because I never made this
feature public.
