[Bluez-users] bluepin bash script with immediate pin response

[Burkhard Fischer <b.fi2@web.de>]

Hello,

I am using BlueFRITZ! USB Bluetooth dongle, the BlueFRITZ
AP-ISDN and ciptool for establishing a connection.

I want to replace the python script bluepin with a simple shell script 
to avoid interactive authentication. A simple echo should do this, 
however I found out that a connection is only established when the 
bluepin bash script doesn't answer immediately.

Here is the syslog:

Jan 20 16:59:02 magito hcid[544]: pin_code_request 
(sba=00:04:0E:82:F9:74, dba=00:04:0E:84:06:CA)

Jan 20 16:59:34 magito kernel: hci_cmd_task: hci0 command tx timeout

and with "sleep 1" before echoing the pin everything goes well (besides 
the occasional tx timeout):

Jan 20 17:15:12 magito kernel: capi: controller 1 up

I am using 2.4.24 kernel with the mh1-Patch and the source 
bluez-libs-2.5.tar.gz
bluez-utils-2.4.tar.gz
bluez-sdp-1.5.tar.gz

Is there a reason for this behavior

thanks
Burkhard
