Personal Area Network bluetooth profile

So, does anyone know if the Tablet can use this profile and if so, can it used to access the interweb?

Someone else has posted a question about the T-mobile Dash (that has the PAN profile but not the DUN profile) here, but I figure this is the root of the problem.

current system does not support it officially but since it is linux and debian it can be made to work. Instructions are in maemo wiki. Something has been mentioned also here, just use the search. You need dummy IAP connection configured and setup script in shell which starts pand daemon and sets up dns and IP address. Works for me with my notebook with conection sharing over Bluetooth LAN Access Server (part of widcomm bt stack) in Windows XP.

But the other way around...

I was wondering how to configure the 770 to share a WiFi connection over BT PAN, or even a BT 3G connection that could be shared over PAN. Is this doable, any hints, links etc :)

I have a Sony Ericsson M600i that supports surfing over BT PAN, but since I have a free 3G (WCDMA) access with my other cellphone (corporate), it would be cool to share that connection from the 770 to the M600i, or even an active WLAN connection.

fanoush, do you have a script I can copy off of? :)

up script

Code:

#!/bin/sh

# use gainroot to become root and relaunch itself

if [ `id -u` != 0 ] ; then

#if not already root, call itself as root

        sudo gainroot <<EOF

$0 $*

EOF

        exit

fi

# real script follows

BTADDR='xx:xx:xx:xx:xx:xx'

IP=192.168.2.2

GW=192.168.2.1

NS=192.168.2.1

IFACE=bnep0



#insmod just to be sure

insmod /mnt/initfs/lib/modules/current/bnep.ko

#start PAN Bluetooth connection

pand --connect $BTADDR



# wait for the interface created by pand

s=60

echo -n "Waiting $s secs for $IFACE"

while [ $s -gt 0 ] ; do

        ifconfig $IFACE >/dev/null 2>&1 && break

        s=$((s-1))

        echo -n "."

        sleep 1

done

echo

if ifconfig $IFACE >/dev/null 2>&1 ; then

# bring it up

echo "OK, bringing $IFACE up"

ifconfig $IFACE $IP up

route add default gw $GW

echo "nameserver $NS" >/tmp/resolv.conf.lo

else

    echo "Error: $IFACE not available."

fi

down script

Code:

#!/bin/sh

# use gainroot to become root and relaunch itself

if [ `id -u` != 0 ] ; then

#if not already root, call itself as root

        sudo gainroot <<EOF

$0 $*

EOF

        exit

fi

# real script follows

echo -n '' >/tmp/resolv.conf.lo

pand -K

sleep 1

rmmod bnep

you need to open dummy connection before executing 'up' script or DNS details wil get overwritten in /tmp/resolv/conf.lo

sweet! that worked. Thanks!

Did you have to enable R&D mode so the script would work correctly?

I have becomeroot installed as well as dropbear as well but I'm trying to figure out how to streamline connecting so its less painful.

Yes either that or after you become root by other ways you can modify /sbin/gainroot as described here (step 4) http://maemo.org/maemowiki/HowDoiBecomeRoot2

IMO becomeroot should modify /sbin/gainroot to be compatible with R&D mode and not play with /etc/sudoers and invent another way of becoming root.

fanoush: agreed entirely. Is there an email address for the author somewhere?

Why not. Probably this is good idea.

everything worked out. Thanks guys. Wish Nokia would incorporate something more elegant in the update but this will do.

Done. Only changed in gainroot, not sudoers.

Thanks. That will make life easier for people creating/using scripts which need root.

Code:



#!/bin/sh

# use gainroot to become root and relaunch itself

if [ `id -u` != 0 ] ; then

#if not already root, call itself as root

        sudo gainroot <<EOF

$0 $*

EOF

        exit

fi

I get a segmentation fault with this part active. Anyone else have a problem with using this technique to gainroot from a user script?

FYI: I have a samsumg blackjack on cingular and the following ip setup was necessary

IP=192.168.0.170
GW=192.168.0.1
NS=192.168.0.1

www.dslreports.com/mspeed give 365kbps one the 770. (laptop usb tethered 1mbps, BT on laptop is about the same as the 770)
