[Bluez-users] hcid crashing on pin_code_request

[Bluez-users] hcid crashing on pin_code_request

[Rolf S. Dubitzky]

Hi,

I try to pair my jabraBT200 headset with a USB-BT dongle on FedoraC4.  
(details below) I used the dongle to communicate with the phone and that 
works just fine.  The headset works fine with the phone as well.  I suspect, 
that I have a compatibility problem with the package mix on my FC4 box (see 
below), since when starting hcid -n I get the following backtrace in the very 
second I try to communicate with the headset (e.g. l2ping and headset in 
pairing mode): (I tried  security auto; and   security user; but the pin 
helper isn't even started. hcid crashes before that I asume)

Thanx for any help, Rolf

[Bluez-users] Re: hcid crashing on pin_code_request

[Rolf S. Dubitzky]

Ok,

I guess the standard answer is to compile the latest version ;-)  Which 
actualy helps.  I gues I have paired the devices now, but still no cigar.
When starting btsco it complains: 

 # /usr/local/bin/btsco -v -r -s 00:07:A4:03:97:24
 btsco v0.4c
 Device is 1:0
 Error: Failed to connect to SDP server: Connection timed out
 Assuming channel 2

 Voice setting: 0x0060
 Can't connect RFCOMM channel: Resource temporarily unavailable

sdpd is running. 

 # ps -C sdpd
   PID TTY          TIME CMD
 27407 ?        00:00:00 sdpd

what to do?  I follow the HOWTO on http://bluetooth-alsa.sourceforge.net/ 
which doesn't mention RFCOMM. 

The hcidump from starting btsco is below. Do I need to add something 
in /etc/bluetooth/rfcomm ??

output of hcitool info, aplay -l, various sdptool calls are below.

Cheers, Rolf

I fixed this problem by including:
         auth disable;
         encrypt disable;
in /etc/bluetooth/hcid.config. I hope ot works for you too :)

[Bluez-users] Re: hcid crashing on pin_code_request

[Rolf S. Dubitzky]

[-- Attachment #1: Type: text/plain, Size: 1144 bytes --]

Hi,

I got it to work now.  For completeness:

1)  the bluez packages (see original post) in FedoraC4 are broken.  They 
    don't work and crash in the way I posted.
    => get latest version and compile yourself

2)  the current version of bluez-utils (2.22) doesn't compile propperly on 
    FC4.  The ./configure doesn't find the dbus libraries and just doesn't
    compile with dbus support, but without dbus support bluez is unusable for
    me.   I would concider this to be a bug in bluez, but ymmv.  
    Now without dbus support sdp doesn't work, e.g. sdptool browse just 
    returns

     Failed to connect to SDP server on 00:07:A4:03:97:24: Connection timed 
     out

    So if a tool doesn't work without dbus, I'd highly recommend to make dbus 
    a requirement, not an option.

    The problem with compiling on FC4 is that for some funky reason dbus 
    headers are spread over two directories:
      /usr/include/dbus-1.0/dbus/* (e.g. dbus.h)
    and one other file in
      /usr/lib/dbus-1.0/include/dbus/dbus-arch-deps.h
    So you have to -I _both_ directories to make #include dbus/dbus.h compile.
    

Cheers, Rolf
