Hello,
I've got two questions regarding bluetooth in FreeBSD:
1) I'd like to start rfcomm_pppd automatically upon connecting my BT
dongle. I know about /etc/devd.conf but from my understanding only one
action takes place and there's already action for ubt device and so I don't
know how to trigger my script.
you do not really have to do it. you can run rfcomm_pppd even if no
bluetooth devices are connected to the system. basically, all you need
to do is to run both sdpd and rfcomm_pppd bound to wildcard (aka ANY)
bd_addr.
1) to enable sdpd at boot time just add to your /etc/rc.conf the following line
sdpd_enanble="YES"
this should start sdpd on boot automatically. to start/stop sdpd at run time use
/etc/rc.d/sdpd start/stop
2) please cut and paste the following rc script into
/etc/rc.d/rfcomm_pppd_server
==
#!/bin/sh
#
# $FreeBSD$
#
# PROVIDE: rfcomm_pppd_server
# REQUIRE: DAEMON sdpd
# BEFORE: LOGIN
# KEYWORD: nojail
. /etc/rc.subr
name="rfcomm_pppd_server"
rcvar=`set_rcvar`
command="/usr/sbin/rfcomm_pppd"
command_args="-s"
start_precmd="rfcomm_pppd_server_prestart"
required_modules="ng_btsocket"
rfcomm_pppd_server_prestart()
{
if [ -n "${rfcomm_pppd_server_bd_addr}" ]; then
command_args="${command_args} -a ${rfcomm_pppd_server_bd_addr}"
fi
command_args="${command_args} -C ${rfcomm_pppd_server_channel:-1}"
command_args="${command_args} -l
${rfcomm_pppd_server_label:-rfcomm-server}"
if checkyesno rfcomm_pppd_server_register_sp ; then
command_args="${command_args} -S"
fi
if checkyesno rfcomm_pppd_server_register_dun ; then
command_args="${command_args} -D"
fi
}
load_rc_config $name
run_rc_command "$1"
==
3) to enable rfcomm_pppd server at boot time just add to your
/etc/rc.conf the following line
rfcomm_pppd_server_enanble="YES"
rfcomm_pppd_server_channel=1 # EDIT THIS IF NEEDED
rfcomm_pppd_server_label="rfcomm-server" # EDIT THIS IF NEEDED
rfcomm_pppd_server_register_sp="NO"
rfcomm_pppd_server_register_dun="NO"
this should start rfcomm_pppd server on boot automatically. to
start/stop rfcomm_pppd server at run time use
/etc/rc.d/rfcomm_pppd start/stop
2) I've got two ppp.conf profiles, one for FreeBSD and one for Windows.
When I connect FreeBSD laptop via rfcomm_pppd it works and caches the hcsec
key. But if I try to connect Windows machine, it asks for password and it
seems the key is changed as from that time I cannot connect FreeBSD machine
and I have to remove hcsecd.keys and restart hcsecd. Why and what can be
done about it ?
I'm not really sure what are you trying to do. before giving any
suggestions, i'd like to see hcsecd.conf and hcidump that shows the
problem with authentication.
thanks,
max
p.s. please keep freebsd-bluetooth@ in the cc list
Hallo Max,
1) I did'n know it. Thanks for your explanation. I used it the same
way only I ran rfcomm_pppd manually. And btw will the provided rc.d
script be included in FreeBSD ?
2) What am I trying to do ? Well, I set up internet sharing on my home
laptop via BT and I can use it from my other laptop. Now, it works when
my other (work) laptop runs FreeBSD. When I boot the other laptop in to
Windows it asks me for PIN and then it works OK. But when I boot in to
FreeBSD again I cannot connect and I have to reinitialise as explained
in my original email. So to me it seems connecting from Windows somehow
changes stored key which is unusable for subsequent FreeBSD uses.
If this explanation is not enough, I can try to capture and provide
hcidump for you.
Cheers,
Martin
