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 ransceiver and baseband. It uses CSR Bluecore 04-External single chip Bluetooth system with CMOS technology and with AFH(Adaptive Frequency opping Feature). Hardware features: Typical -80dBm sensitivity Up to +4dBm RF transmit power Low Power 1.8V Operation ,1.8 to 3.6V I/O PIO control UART interface with programmable baud rate With integrated antenna With edge connector. Software features: Default Baud rate: 38400, Data bits:8, Stop bit:1,Parity:No parity, Data control: has. Supported baud rate: 9600,19200,38400,57600,115200,230400,460800. Given a rising pulse in PIO0, device will be disconnected. Status instruction port PIO1: low-disconnected, high-connected; PIO10 and PIO11 can be connected to red and blue led separately. When master and slave are paired, red and blue led blinks 1time/2s in interval, while disconnected only blue led blinks 2times/s. Auto-connect to the last device on power as default. Permit pairing device to connect as default. Auto-pairing PINCODE:?0000? as default Auto-reconnect in 30 min when disconnected as a result of beyond the range of connection
