[Bluez-devel] pairing problem

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[7340]: PIN helper exited abnormally with code 256

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

Hi Charles,

Issint the "auto" option suppose to work for outgoing connections also?

when I do ....

bash$ rfcomm connect 0 xx:xx:xx:xx:xx:xx

my cellphone askes for a pin, I type it in and then the cumputer it brings up bluepin asking for a pin. issint is suppose to the the default one in /etc/bluetooth/pin ?

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.

Regards

Marcel
