HC-05 Bluetooth Module code for Arduino

HC-05 module is an easy to use Bluetooth SPP (Serial Port Protocol) module, designed for transparent wireless serial connection setup.
Serial port Bluetooth module is fully qualified Bluetooth V2.0+EDR (Enhanced Data Rate) 3Mbps Modulation with complete 2.4GHz radio transceiver and baseband. It uses CSR Bluecore 04-External single chip Bluetooth system with CMOS technology and with AFH(AdaptiveFrequency Hopping Feature). It has the footprint as small as 2.7mmx27mm. Hope it will simplifyyour overall design/development cycle.
