What is Bluetooth 1.2? - Explained

Bluetooth 1.2 is the version which released after the Bluetooth v1.1. With the advancements in Bluetooth 1.1, Bluetooth 1.2 got even advanced as a technology platform.


Bluetooth version 1.2 used the same UHF signals to within the frequency range of 2.4GHz to 2.485GHz to operate the wireless technology.

Bluetooth 1.2 was the initial version where it enabled the feature to enable discovery of device by bluetooth technology. In addition, by enhancing the RSSI or Received Signal Strength Indicator, a new feature got implemented named faster connection. 

Bluetooth v1.2 adopted the frequency hopping spread spectrum of AFH to avoid the interference issues which occurred in the Bluetooth version 1.0, 1.0B and 1.1.

By making a new record, Bluetooth 1.2 ahcived higher speed upto 721Kbit/s of transferring data by using the wireless Bluetooth technology. 

In the bluetooth version 1.2, the technology got embedded with extended synchronous connections also known as eSCO. eSCO enabled the capability of improving data packet quality and to avoid currupted data packets by synchronize with the both devices and getting updates of the quality of data packets which received by the transmitting device and re-transmitting any data packets which got currupted. 

Bluetooth version 1.2 adopted IEEE 802.15.1-2005 standard to improve the transmission quality. 

Further the bluetooth version 1.2 got advanced with Host Controller Interface also knwo as HCI to operate with three wire UART.
