What is Bluetooth Technology?

Bluetooth is a wireless technology, it is used to transfer data between two different electronic devices without the help of cables, cords and adaptors. The distance between them ranges from 10m to 100m.

The development, licensing and trademarking of Bluetooth was formed in 1998 by the Bluetooth Special Interest Group (SIG). This technology has evolved significantly over the last 20 years and is available in most electronic devices, like headphones, speakers, smartphones, smartwatches, computers and many more. It has become an essential factor in everyday life.

How Bluetooth Works

Bluetooth technology has a personal area network or piconet, containing 2-8 Bluetooth peer devices. A master is a device that initiates communication with other devices. The master device administers the communications link and traffic, between itself and slave devices. A slave device is a device that responds to a master device. Slave devices must synchronize within the given time slot with the master device.

Transmissions by slave devices are governed by master devices. Exactly, a slave device may only begin its transmission in a time slot, addressed by the master.  Here the master device dictates when the slave device has to transmit.

The hopping frequency sequence is well-defined by the Bluetooth device address (BD_ADDR) of the master device. The master device then sends the first radio signal to the particular slave device within the range.

Then the slave device responds and synchronizes their hop frequency, as well as the clock of the master device. Scatternets are created when the device becomes an active member of more than one piconet. The adjoining devices share their time slots among different piconets.
