How do u use Bluetooth Technology?

Question

Please help....i dont know how it works but i want to use it.

what is a passkey? why do i need it?

Answer 1

The passkey should be in one of those paper come with your bluetooth. You will need to use it to connect with another device for the very first time.

Answer 2

passkey is the key you a sight when pairing your phone with other then when you try to send a file by bluetooth it will ask the other phone for passkey both phone need have the same key for example i wanna send you a song , i have to find you phone first

Answer 3

For a lot of bluetooth devices the passkey is just 4 0's I believe because I just got mine the other day and that was the pass key for mine. The point of it is so that only you use it and not anybody else. I think you can change it but I'm not sure. However, you'll need a bluetooth compatible phone, if you have it, you put the option to search for bluetooth devices, and at the same time, you turn on the bluetooth until it flashes (discovery mode) and then you select your bluetooth device on the phone, enter the passkey, and you're good to go. However, you might need to make some changes to the phone settings like how you want to answer, auto answer, flip open the phone, etc.
