HC-05 Bluetooth Module is an easy to use Bluetooth SPP (Serial Port Protocol) module, designed for transparent wireless serial connection setup. Its communication is via serial communication which makes an easy way to interface with controller or PC. HC-05 Bluetooth module provides switching mode between master and slave mode which means it able to use neither receiving nor transmitting data.

  • Frequency: 2.4 GHz ISM band
  • Modulation: GFSK (Gaussian Frequency Shift Keying)
  • Transmit power: Class 2 (up to 4 dBm)
  • Sensitivity: -80 dBm typical
  • Range: approximately 10 meters (or 33 feet) in open air
  • Profiles supported: SPP (Serial Port Profile), HID (Human Interface Device) and others
  • Operating voltage: 3.3V to 5V DC
  • Operating current: less than 50mA
  • Standby current: less than 2.5mA
  • Sleep current: less than 1mA
  • Interface: UART (Universal Asynchronous Receiver/Transmitter)
  • Baud rates: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, and 460800
  • Operating temperature: -20°C to 75°C (-4°F to 167°F)

Pin Configuration

Pin Number

Pin Name

Description

1

Enable / Key

This pin is used to toggle between Data Mode (set low) and AT command mode (set high). By default it is in Data mode

2

Vcc

Powers the module. Connect to +5V Supply voltage

3

Ground

Ground pin of module, connect to system ground.

4

TX – Transmitter

Transmits Serial Data. Everything received via Bluetooth will be given out by this pin as serial data.

5

RX – Receiver

Receive Serial Data. Every serial data given to this pin will be broadcasted via Bluetooth

6

State

The state pin is connected to on board LED, it can be used as a feedback to check if Bluetooth is working properly.

7

LED

Indicates the status of Module

  • Blink once in 2 sec: Module has entered Command Mode
  • Repeated Blinking: Waiting for connection in Data Mode
  • Blink twice in 1 sec: Connection successful in Data Mode

8

Button

Used to control the Key/Enable pin to toggle between Data and command Mode
