bluepin bash script with immediate pin response

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):

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

Hi Burkhard,

show us the dump (hcidump -w <file>) for a connection setup.

Regards

Hi

here some more informations and the attached hci dump

/bin/bluepin:

#!/bin/bash
#sleep 1
echo "PIN:6bkgLuRqDpSIYZgP"

command:

magito:/etc/bluetooth# ciptool connect 00:04:0E:84:06:CA
Can't connect L2CAP socket: Connection refused

Hi Burkhard,

the problem seems to be the AP itself, because l2cap_conn_rsp with result code 4 means "Connection refused - no resources available". Try to update the firmware of your AP.

Regards

Marcel
