Overview

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.

+'''Application Example'''
+This is a demo that HC-05 is a master device and communicates to
+hc-06.
+Step 1. Push the mode switch to CMD
+Step 2. Power on, module enter command state
+Step 3. Using baud rate 38400, send the ―AT+ROLE=1\r\n‖ to module,
+with ―OK\r\n‖ means setting successes.
+Step 4. Send ―AT+CMODE=1\r\n‖, set HC-05 connect to any address,
+with ―OK\r\n‖ means setting successes.
