Bluejacking

Almost every modern mobile phone has Bluetooth. This is a great tool for communicating with people within a radius of 10 (and often more) meters. Do you want to find new friends? Make a compliment to the girl you like, but feel free to tell her face? You have nothing to do in the morning in the train, bus or subway, where the phone does not catch at all?

All you need to start a conversation is nothing: turn on Bluetooth and the presence of receiving devices in the environment. Communication tools are already built into your phone.

I. How to create and send a message

1. First, of course, you need to turn on BlueTooth in the phone, about which menu item it is written in detail in the instructions. Some phones by default include Bluetooth always and put the battery on
')
2. Give the phone a meaningful name indicating at least gender. It is not recommended to change nicknames often, perhaps a person would be happy to talk with you again, but he didn’t see you in person, he doesn’t know your phone number and so on ...

3. Set Bluetooth discovery mode “available to all” so that other participants can find you.

4. Now we go to the notebook. Create a new contact, instead of the name and surname we write a couple or three greeting words. Remember that in different phones the order of sorting contacts is different, i.e. surname and name can be interchanged. It is better to abandon the use of these two fields at the same time, just write in one of them - either in the first name or in the last name. Remember that not all phones support a large number of characters and spaces in one field of the notebook, 2-3 words is the maximum. In the "phone", as well as the rest do not write. We save the contact and immediately select it in the notebook → Send via BlueTooth. The phone will start scanning the surroundings for available devices and will list them. Choose one of them and click "Send".

5. Read the instructions for your phone if something is not clear.

6. The method of sending an empty contact is universal and has no analogues.

Ii. Safety and tact cart

1. If the subscriber does not respond to your message, then he either does not know how to do this, or is afraid of viruses. Do not bother him further. CONTACT TELEPHONE BOOK CAN'T CARRY ONE VIRUSES.

2. File transfer is a very insecure thing. You should not accept files other than MP3 and JPG, GIF, etc. from unknown devices. To infect and disable your phone with their help is impossible. Be careful about the jar, jad, sis, sisx, exe, class files and the like. Do not take them.

3. File transfer may require pairing of two devices, but it is impossible if you do not enter a pin — the connection code — from 1 to 4 digits. Simply, both participants must enter the same numeric sequence. You can worry about this in advance, for example, by assigning to the nickname of your device, for example, "(password 321)". I repeat. This can be any number from 1 to 4 of any digits, the main thing is that at the moment of pairing both parties enter it in the same form. See your phone manual for more details.
