Overview

HC-05.jpg

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(Adaptive Frequency Hopping Feature). It has the footprint as small as 12.7mmx27mm. Hope it will simplify your overall design/development cycle.

Specifications

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.
