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

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.

AT command Default

How to set the mode to server (master):

1. Connect PIO11 to high level.

2. Power on, module into command state.

3. Using baud rate 38400, sent the “AT+ROLE=1rn” to module, with “OKrn” means setting successes.

4. Connect the PIO11 to low level, repower the module, the module work as server (master).

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=1rn‖ to module, with ―OKrn‖ means setting successes.

Step 4. Send ―AT+CMODE=1rn‖, set HC-05 connect to any address, with ―OKrn‖ means setting successes.
