HC-05 Wireless Bluetooth Master Slave Module

Using mainstream CSR Bluetooth chip, Bluetooth V2.0 protocol standards; Serial module operating voltage 3.3V, 10 meters from the general. The main steps of setting module: 1. High PIO11. 2.Electricity, module into the AT command response state. 3.The super terminal or other tool, set the baud rate 38400, 8 data bits, 1 stop bit, no parity bit, and no flow control. 4. Send characters "AT+ROLE=1rn", "OKrn" successful, rn return. 5. PIO is set low, re power, module as the main module, automatically search from the module, to connect. Serial port bluetooth, Drop-in replacement for wired serial connections, transparent usage. You can use it simply for a serial port replacement to establish connection between MCU and GPS, PC to your embedded project and etc. HC-06 has be designed Master or Slave when the factory, user couldn't change the role.

Usage

After pairing only need as fixed baud rate of the serial port as can be, so long as it is "fixed baud rate, 8 data bits, no parity" serial communication format equipment can be a direct replacement for the original wired serial port without the need to modify the program. Such as data acquisition, smart car, serial printer, outdoor lattice strip screen control.Paired with computer use: for computers and devices via Bluetooth serial communication, use serial paired with the phone use: suitable for the mobile phone with the device through Bluetooth serial communication, use serial paired with the Bluetooth host: for the two devices directly through the Bluetooth serial communication between the microcontroller and the microcontroller wired serial interface with microcontroller between use with serial
