 Task 1

  
Setup of Bluetooth, Mobile phone setup
On laptop. Plugin bluetooth dongle into USB port, if it’s the 1st time you’re doing this, wait while Windows installs the device.
On you phone: Enable Bluetooth on your phone, and keep it switched on for the duration of the setup.
On Sony Ericsson K750i-> Menu -> Settings -> Connectivity -> Bluetooth -> Bluetooth On
On Laptop. Add a new bluetooth device (your mobile phone)
Select ‘My device is set up..’ and press next to search for device

 

If the phone was found after searching for it, the following is displayed…

 

 Check the following:
1- If the phone is switched on and that the bluetooth is enabled.
Check for the ((º)) symbol on the display of the mobile phone. This shows the bluetooth is on.
2- If you are sure that the bluetooth is enabled on the phone, ensure that you have disabled any other 3rd party Bluetooth software – if it was installed as it may conflict with the standard drivers on the system.

 

Following the next step, after successful detection of the mobile phone, you will be prompted which passkey mechanism to use, select ‘Let me choose, my own…’ and enter a passkey. In this example I use 0000

 

  

After the next step, the phone should now display…

<Computer Name>

Press Accept on phone.

You’ll now see some messages displayed on the tasktray (next to clock as the device is installed)

During the installation new COM ports will be added to Windows which are associated with Bluetooth and the communication with the phone. It is important to make a note of the ‘Outgoing COM port’ as you will have to select it at a later stage.
In this example we make a note of COM port 3 as we need to select it during the DUN setup.

Back at the Bluetooth devices form, the display will now show the phone and that the passkey is enabled.

 Task 2 

Check if the Bluetooth Modem link has been configured. 3

On XP -> Control panel -> click the ‘Phone and Modem Options’->Modems Tab

 Notice that a Modem has been installed over the Bluetooth link, the attached com port may differ for your system.

If the bluetooth link is not shown :
- cancel the dialog, ensure that bluetooth is enabled on your phone, then return to this dialog.
- if is still does not display then you have a few options :
option 1. manually add a modem connection. Click for how to manually add a cellphone serial modem link via bluetooth.
option 2. install the Bluetooth modem drivers for the Bluetooth dongle that you received with the dongle.
option 3. get another Bluetooth dongle that is natively supported by Windows XP and does not require additional driver installation.

You can test if the modem enables the phone, by selecting Properties->then the ‘diagnostics tab’ then ‘Query Modem’

This should result in the laptop attempting to query the modem, which now is the mobile phone, the phone will display a message

Connect with?

   Task 3 

Setup op GPRS on the mobile phone. -Sony Ericsson K750iFor Sony Ericsson K750i the GPRS access point can be configured :
Menu->settings->tab connectivity->internet settings->internet profiles->
edit or create a new profile. If you are creating a new profile, follow the settings below when asked which data account to use.

 

When asked for “Connect Using”, create a new data account:

Connect Using -> New Account -> GPRS data -> Enter an accounts name such as WAP GPRS

The screen should show “New GPRS data”. Enter the following values for the settings:

APN: internet

Select to use a dial-up modem.

  

 

Now only select a single option – the Bluetooth link on the COM port that was installed earlier, in this example it is COM 3, but it may well be different to your computer.

 

3

 

 

 

If the link is NOT shown then Click for how to manually add a cellphone serial modem link via bluetooth.

  

Task 5

Now enter a name for the dialup

You are now ready to attempt an internet connection!

If the link is NOT shown then Click for how to manually add a cellphone serial modem link via bluetooth.

Now enter a name for the dialup 

3

 

For the phone number use *99#
NOTE: This will instruct the phone to use the default or 1st GPRS profile on your phone. If you have multiple profiles GPRS profiles on your phone and you do not want to use the default profile, the change the phone number to *99*n# and replace the n with number 1-9 of the profile you want to use.
3
 
 Then leave the username, password empty!
Decide if you want to make this the default connection or not.

3

 Finally decide if you want to make icon on desktop fro this connection

 

 3  

You are now ready to attempt an internet connection!

3

 Once again leave the username and password empty and press dial.

The mobile phone will display
‘Connect w
ith?’
<compu3ter name>

Accept this

and on XP, you’ll see

  If all is well you see the following

  

3Also notice on the mobile phone that the GPRS symbol has changed to G in a frame- this means it’s connected!

You are now ready to surf the internet and download email etc.

 


2. What I’ve noticed is that if you are roaming abroad and not using your home network, you may have to supply a username and password for the dial-up connection for the network you are using. Once again contact the network provider for this.  Task 6 



 

 Connected, but cannot access websites. Error such as “The page cannot be displayed”

The dialer shows that a connection has been established, but when you try to access a website the page error “The page cannot be displayed” is shown. This ma ybe a DNS error, the connection cannot locate the Dynamic Name Server. After extensive testing, the following was established:
-this problem was only on a XP system with Service pack 2 build 2149
-supplying a correct DNS address in the IP setup of the dialup network connection, did not resolve the issue.
- a workaround was to supply a manual GPRS connection string for the modem.
- installing the latest service pack did resolve the issue.

Part 5c: Dials, send login information, but fails on registering on network
- you probably have multiple GPRS accounts configured on the phone, and the DUN is using the incorrect one. Several solutions to this: On the phone swap the GPRS accounts, such that the one that can connect is first, or change the DUN dialer to include the number of the GPRS connection you wish to use. If you have a phone that the default access point can be set, check that the name of the access point is correct.

 

3 On XP -> Control panel -> click the ‘Phone and Modem Options’-> Modem Tab ->Modem Link -> Properties -> Advanced Tab

  

3

 

 Select the Bluetooth modem link and press ‘Properties’ button. Then on the Advanced Tab of the dialog that is shown, locate the input ”Extra initialization commands”.
Enter the following text and press OK
+CGDCONT=1,”IP”,”internet”

For Virgin Mobile (South Africa) supply the additional parameters
+CGDCONT=1,”IP”,”vdata”,”",0,0
Note that the name “internet” may be different to your network, although this is used by most providers, you may have to change it. The 1 denotes GPRS account number that will be modified. Most Sony Ericssonphone support several GPRS accounts.
NOTE: This setting may actually override your GPRS settings for the specific account on the phone.
3
 

 Click OK, and close the dialogs, then attempt the DUN again. For this example Start Bar-> Connect To->Sony Ericsson K750i.

 

 
 

Task 7

Manual setup of the GPRS initialization. As indicated earlier, if you experience connection issues, another approach is to force the mobile phone to use a specific GPRS connection. This will override any setup of the GPRS settings on the phone itself. 

 

 
 Task 8

 Connection issues If you get the message ‘Subscribe to GPRS first’ the following may be wrong.1. Most likely cause : the GPRS access point is incorrect. Contact your service provider to get the correct name for your network.
