Hi list,
I'm having trouble with Bluez. I think I'm almost there, however. Here's
the description:
I have successfully set up the hci0 device:

And I have paired my PC with my Sony Ericsson K700i Cellular Phone:
# hcitool scan
Scanning ...
00:0E:07:A7:7E:D2 K700i
# hcitool cc 00:0E:07:A7:7E:D2
# hcitool auth 00:0E:07:A7:7E:D2
# hcitool dc 00:0E:07:A7:7E:D2
The cell phone asks upon the "auth" command if it shall connect to
"Joeserver" and asks for the PIN. When I enter the correct pin (stored
in /etc/bluetooth/pin) the devices are paired.
Everything looks fine so far. Then comes the rfcomm:
# rfcomm bind 0 00:0E:07:A7:7E:D2 1
Now when I try, for example:
# cat > /dev/bluetooth/rfcomm/0
- -bash: /dev/bluetooth/rfcomm/0: Connection refused
#
I also tried changing channels from 1 to 12. On 6 it just blocked, but
the cellphone didn't display anything. All other channels said
"connection refused".
Then I read the mailing list and some message there said to use sdptool:
# sdptool browse 00:0E:07:A7:7E:D2

Channels appear to be 1, 2 and 3 (which I tried, as mentioned above).
Here's my /etc/bluetooth/hcid.conf (all comments removed)
options {
autoinit yes;
security user;
pairing multi;
pin_helper /etc/bluetooth/pin-helper;
}
device {
name "Joeserver";
class 0x3e0100;
iscan enable;
pscan enable;
lm accept;
lp rswitch,hold,sniff,park;
}
And this is my /etc/bluetooth/rfcomm.conf:
rfcomm0 {
bind yes;
device 00:0E:07:A7:7E:D2;
channel 1;
comment "Handy";
}
(it only gets read on startup, I have set up the bindings to channel
1-12 manually).
Would a dump of hcidump be helpful? What exactly should I dump?
I would really appreciate if somebody could help, Bluez is already a
really impressive piece of work. It worked (until now) so smoothly, I
was really impressed :-)
Greetings,
Johannes

Well, I read several HOWTOs, it was mentioned in one.
Hope the log helps,
