Bluetooth basic...

Bluetooth got its name from the name of a king of Denmark
Harald Bluetooth. Who united many Danish tribes to a single kingdom, in the similar ways Bluetooth connects different devices together.
This is nothing but the respect and honor given like many of the constants and units are based on great scientist.
Now Bluetooth is a well known standard for PAN.
Bluetooth is further consisting of many profiles to support different features.

we mainly use below profiles :-

1-Hands free profile - for hands free mode of our mobile phone
2-A2DP - means advance audio distribution profile for playing audio via Bluetooth like in our car audio.
3-Object push profile - for sharing data between two devices.

So for each function there is a separate profile. A practical example is that my phone hands free support only the hands free profile but not the A2DP so i can only use my hands free during calling but not for hearing music.........
