The HC-05 module is an easy to use Bluetooth module, designed for transparent wireless serial connection setup. It can be used in a master or slave configuration. The serial port is fully qualified Bluetooth V2.0+EDR (Enhanced Data Rate) 3Mbps Module with a complete 2.4GHz radio transceiver and baseband. It uses the CSR Bluecore 04-External single-chip Bluetooth system with CMOS technology and with AFH (Adaptive Frequency Hopping Feature). It has the footprint as small as 12.7mmx27mm.
These modems work as a serial (RX/TX) pipe. Any serial stream from 9600 to 115200bps can be passed seamlessly from your computer to your target.The remote unit can be powered from 3.3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant. No level shifting is required.Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit if you need to attach this to a computer.
- Default Baud rate: 38400, Data bits:8, Stop bit:1,Parity:No parity
- Supported baud rate: 9600,19200,38400,57600,115200,230400,460800.
- Given a rising pulse in PIO0, the 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 the 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.
