Bluetooth

Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronization.

In time evolutionary point of view Bluetooth technology started in 1998,  the three most important Bluetooth technology evolution are version 2.1 + EDR - secure, simple pairing in 2007 and the second one was version 3.0 - high speed in 2009, and the third one was version 4.0 - Low Energy in 2010. Bluetooth version 4.0 was a new way of transferring data between two devices with very low power.

Bluetooth BR/EDR/HS uses time division multiplex where time is divided into 625 uS slots and data is exchanged via packets, there are two types of data exchange mode one is Asynchronous Connection-oriented logical transport (ACL), and another one is Synchronous Connection-oriented link (SCO), Enhanced SCO (eSCO), in simple ACL is for data transfer and whereas  SCO and eSCO is for voice.

Bluetooth  Low Energy  ISM band split into 40 channels of two types; one is Advertising Channels and other is Data Channels. Advertising Channels are three fixed channels those are channel 37 frequency of 2402MHz, channel 38 frequency of  2426MHz, and channel 39 frequency of 2480MHz. Data Channels are those channels used to transfer a large amount of data, and those channels are channels 0 -10 frequency from 2404 - 2424 MHz and channels 11 - 36 with frequency from 2428 - 2478 MHz.
