It uses CSR Bluecore 04‐External single chip Bluetooth system with CMOS technology and with AFH (Adaptive Frequency Hopping Feature).

HC-05 Bluetooth Module is now more popular due to its low price and extremely high features.

This module can be used in Master or Slave Mode and easy switchable between these two modes, By default Slave mode is configured.Modes can be changed using AT Commands.

The slave mode in HC-05 cannot initiate a connection to another Bluetooth device, but can accept connections.Master mode can initiate a connection to other devices.

Here is a very nice tutorial of interfacing the bluetooth module with Android app and Laptop.

In case you are looking at BLE or Bluetooth v4, check this module.
