The document describes the steps that I took (minus all the wrong ones, and there were many) to get a successful GPRS data connection using my Sharp Zaurus PDA, a Nokia 6310i, a Socket Bluetooth card and an O2 (UK mobile phone operator) GPRS data account, I hope it helps you.
I’m making the assumption that you already have a Sharp Zaurus (Z) (or are intending to buy one) and that you are OK with using Linux on the command line.
Sharp Zaurus PDA
Socket Bluetooth card
Nokia 6310i phone
OpenZaurus 3.1RC1 the alternative to the stock ROM that Sharp ships with the Z.
Affix – Bluetooth Protocol Stack for Linux
I placed all the ipks onto a CF card and installed them using aqpkg, you may need to force deps on a few of them. Reboot the Z and you should have a little (grey) Bluetooth icon on your task bar.
an ‘lsmod’ gives me:
root@zaurus /root# lsmod Module Size Used by affix_uart_cs 3952 1 affix_uart 20496 0 [affix_uart_cs] affix 81584 0 [affix_uart] serial 25952 0 [affix_uart_cs] sharp_mmcsd_m 27424 2 devinfo 3168 0 (unused) sa1100_bi 45536 0 (unused) net_fd 36016 1 [sa1100_bi] usbdcore 20448 0 [sa1100_bi net_fd] usbdmonitor 6112 0
For some reason when I put the card into the CF slot, the card is recognised but I cannot ‘Turn Bluetooth ON’ using the taskbar applet*. So I need to run little script which I have placed in /root/bin
root@zaurus /root# cat /root/bin/bt #!/bin/sh cardctl eject 0 modprobe affix_uart_cs cardctl insert 0 btctl init_uart tlp 115200 ring,ctl,low btctl up
* apparently this is an issue with hwinit and it will be rectified in future affix releases.
When I run this on my Z, I see the card ‘ejected’ and then ‘inserted’ and the little taskbar icon turns blue. I can also see:
root@zaurus /root# btctl Affix version: Affix 1.2.6 ---->>>> Affix Bluetooth Driver control program <<<

So we have a bluetooth card plugged in and ready to roll, next we need to make the bluetooth connection.
Firstly make sure that Bluetooth is enabled on your phone. Next let’s see if the Z can see it.
root@zaurus /root# btctl discovery Searching 8 sec ... Searching done. Resolving names ... done. +1: Address: 00:02:ee:6c:d1:f5, Class: 0x500204, Key: "no", Name: "Nokia 6310i" Phone (Cellular) [Object Transfer,Telephony]
Now we need to pair the phone with the Z. The following adds the PIN of ‘1’ (not great I know) for the pairing
root@zaurus /root# btctl addpin 00:02:ee:6c:d1:f5 "1"
Now lets make the connection:
root@zaurus /root# btctl connect 00:02:ee:6c:d1:f5 Connecting to host 00:02:ee:6c:d1:f5 ... Service found on channel 3
The phone should beep and ask you to accept the connection to ‘Zaurus’ press accept and type in a 1 when asked for the PIN
Connecting to channel 3 ... Connected. Bound to line 0 [/dev/bty0].
Now we need do is set up a ppp link. The following information is specific to my 02 http://www.o2.co.uk GPRS data account. The settings I got from other snippets that I found elsewhere did not work with O2 _at_all_ they needed quite a bit of jiggling around.
Firstly backup your /etc/ppp/options, create a new one and put in it the following
# File: # /etc/ppp/options -detach noauth name web # the O2 GPRS data username defaultroute nocrtscts lock usepeerdns /dev/bty0 115200 local noccp asyncmap a0000
Next make a new directory called chat and place in it the following 2 files
# File: # /etc/ppp/chat/gprs-connect # # Description: # chat script to open O2 GPRS service with Nokia 6310i GPRS phone. # # Modifed from script found at ConnectedUser.com exec chat -v TIMEOUT 5 ECHO ON ABORT 'nBUSYr' ABORT 'nERRORr' ABORT 'nNO ANSWERr' ABORT 'nNO CARRIERr' ABORT 'nNO DIALTONEr' ABORT 'nRINGING....rn' '' 'rAT' TIMEOUT 12 SAY "Press CTRL-C to close the connection at any stage!" OK 'ATE1' OK 'AT+CGDCONT=,,"mobile.o2.co.uk"' OK 'ATDT *99#' TIMEOUT 22 SAY "nTrying to connect...n" CONNECT '' SAY "nConnected." SAY "nIf the following ppp negotiations fail,n" SAY "try restarting the phone.n"
Note these 2 lines
OK 'AT+CGDCONT=,,"mobile.o2.co.uk"' OK 'ATDT *99#'
mobile.o2.co.uk is the APN and *99# is the number to ‘dial’ see http://nds1.nokia.com/phones/files/guides/Nokia_AThelp.pdf [pdf] for more info.
The second file is a disconnect script:
#File: # /etc/ppp/chat/gprs-disconnect # # send break exec /usr/sbin/chat -V -s -S ABORT "BUSY" ABORT "ERROR" ABORT "NO DIALTONE" SAY "nSending break to the modemn" "" "K" "" "+++ATH" SAY "nPDP context detachedn"
Now create a file /etc/ppp/peers/gprs
#File: # /etc/ppp/peers/gprs # # Settings here should work for a Nokia 6310i and a # GPRS data account with O2 (ex BTCellnet) in the UK # Darren Beale - email@example.com debug /dev/bty0 # bluetooth 115200 connect /etc/ppp/chat/gprs-connect disconnect /etc/ppp/chat/gprs-disconnect crtscts defaultroute usepeerdns asyncmap a0000 noccp noipdefault
Nearly there, create a file /etc/ppp/pap-secrets with one line:
web * web
(This is the O2 username and password for a GPRS data account)
also create /etc/resolv.conf and add the lines:
nameserver 184.108.40.206 nameserver 220.127.116.11
I’m sure that here any valid nameserver will do, but these IP’s are correct for O2
Finally create the file /etc/ppp/ip-up.d/routing with the line
route add default gateway 10.6.6.6
again specific to 02.
Now lets try to connect.
At this point I suggest that you make sure syslog is running by typing
you can now open a second terminal window and ‘watch logread’*
* if you can get OZ3.1 running busybox_0.61.pre-20021208-6 to log to a file please let me know how!
To connect type:
pppd call gprs &
Your phone should say that it is establishing a GPRS connection, if it works, you’ll get teh little ‘G’ in the upper left corner.

You’ll need to chmod some of those files so they are executable
Make sure that everything in /etc/ppp is owned by root, i.e.
chmod -R root:root /etc/ppp
