[Bluez-users] rfcomm: permission denied

[Zbigniew Diaczyszyn (gmx)]

I'm working with Suse 8.2 and a Typhoon Bluetooth modem. I had it =
working - once. Now rfcomm is just saying: permission denied. The =
following lines are a protocol of bluetooth session. I have no idea at =
all in which  config-files I should look for a solution. /bin/bluepin =
ist just a < cat /etc/bluetooth/bluepin >. I'm working as root and =
/dev/rfcomm0 ist belonging to root.

this can't work. If you bind the device you don't need an additional
connect. You only have to open /dev/rfcomm0 with pppd or any other TTY
related program.

Hello Marcel,

I have compiled hcidump on my system (suse 8.2), but hcidump seems to =
have crashed down. I had to terminate the process with Ctrl-C:

linux:~ # hcidump -w info.txt
HCIDump - HCI packet analyzer ver 1.5
device: hci0 snap_len: 1028 filter: 0xffffffff

Is this a hardware problem or a wrong compilation of hcidump?

thanks in advance

Zbigniew

no, everything works fine. Terminate it with CTRL-C and send us the

if this happens then there was no traffic on the HCI layer. Check again,
because this can't be true.

yes, hciconfig shows you the local address of your device. For rfcomm
you have to use the remote address.

Well, I tried so once again, but hcidump is silent...

Perhaps the following kernel warning in /var/log/messages can show the =
way to a solution:

The Bluetooth authorization failed, but I can tell you only more if you
send me the dump from hcidump.

Indeed. I'm now able proudly to present the hcidump-activity. Meanwhile =
I have updated to Suse 9.0 and recompiled hcidump. The error message has =
changed :-)

write the binary dump to a file with -w, or show us the output with -x.

Attached you will find the binary file in hcidump.log and the files for the pinhelper-stuff: bluepin is just an cat-command.

the /bin/bluepin script should look like this

	#!/bin/sh
	echo "PIN:0000"

and you must make sure that the script is executable.
