After Selecting option XML and Clicking Ok



PRACTICAL No. 10

Que: File transfer between Laptop & Mobile phone using Bluetooth

Instructions:

Things will Need: Bluetooth enabled PC Bluetooth enabled cell phone

Step 1

Enable Bluetooth on the PC. To enable Bluetooth on the PC visit your control panel. We should see an option for Bluetooth devices. Select this option and make sure the technology is enabled. If you are installing a USB module, we should be able to plug it in and use it right away. If not, it should come with drivers to install (insert the disc, and install the software).

Step 2

Enable bluetooth on the cell phone. Each phone is different, but you should be able to go to a settings menu, and select bluetooth. There should be an option to enable bluetooth on the phone. Enable it, and make sure the phone is visible.

Step 3

Allow the PC to search for devices. It should find the cell phone. If not, we can try searching for the computer with the cell phone. Many times, with the USB modules, they have trouble finding the cell, but the cell can find the computer. The important part is that the devices connect, regardless of which device finds which.

Step 4

Approve the devices to connect. Sometimes, the devices will automatically connect, and we will be ready to go. However, if this is not the case, refer to step 5.

Step 5

Enter any necessary security codes. If you do not know these codes, try the defaults, (1234, last 4 digits of your phone number, etc.).

Step 6


Select the files on the computer that we want, and we should be able to right click and select "send via bluetooth". Click this option, and let the files send.

OR

Another way is with windows XP and blutooth enabled mobile

a) Setup on the Device

Step 1: On the device, press Menu.

Step 2: Scroll to Connect. and press the scroll key.

Step 3: Scroll to Bluetooth and press the scroll key.

Step 4: Scroll to Bluetooth and press the scroll key till On is displayed.

Step 5: Scroll to My phone’s visibility and press the scroll key till Shown to all

is displayed.

Step 6: Scroll to My phone’s name and press the scroll key..

Step 7: Enter Nokia in the field provided and press Ok.

Step 8: Press Exit and End key to go back to main screen.

b) Setup on the Laptop

Step 1: On the laptop, click on Start.

Step 2: Select Control Panel.

Step 3: Select and click on Bluetooth Devices.

Step 4: Click on Add.. and a pop-up “Add Bluetooth Device Wizard” would displayed.

Step 5: Checked on “My device is set up and ready to be found” and press Next.

Step 6: Select on Nokia New device and press Next.


Step 7: Checked “Let me choose my own passkey” and enter an 8 to 16 digit passkey.

Step 8: Press Next..

Step 9: On your device, “Add to My Devices?” is displayed, press Yes.

Step 10: Enter the same 8 to 16 digit passkey that you have entered previously and Press Ok.

Step 11: Please wait while your laptop is installing the Bluetooth.

Step 12: Press Finish when the Completing the “Add Bluetooth Device Wizard” is displayed.
