String command = '' // Stores response of the HC-06 Bluetooth device Unit comes without a connector if you want to connect it to an Arduino Pro, wed suggest the. See the SoftwareSerial library page for more details on its features and limitations. The Bluetooth Mate is very similar to our BlueSMiRF modem.

It has been developed to allow setting upВ serial communication on (almost any) digital pin of the Arduino, using software to replicate ArduinoвЂ™s native serial support. The Software Serial library comes pre-installed with the latest version of the Arduino IDE. It will communicate with your PC over the built in serial connection through the USB cable, and with the HC-06 Bluetooth module over pins 4 and 2, using the Software Serial library. The Arduino will act as a middleman between the Bluetooth module and your computer. The Arduino sketch below will allow you to configure your HC-06 module using the Arduino IDE serial monitor. Step 2: Upload the Arduino HC-06 configuration sketch You do not need the LED on the Arduino pin 13 that I have on my set-up below.

It is designed for 3.3v operation, while the Arduino digital pins work on 5 volts. It is recommended to use a level shifter, voltage regulator (or a voltage divider, like in my set-up below) to protect the Bluetooth module RX pin.

Connect the HC-06 RX/RXD pin to Arduino digital pin 2.

Connect the HC-06 TX/TXD pinВ to Arduino digital pin 4.Connect the HC-06 Ground (GND) pin to ground (duh!).Step 1: Hook up the HC-06 Bluetooth module to the Arduino There are multiple versions of the moduleВ floating around, with different firmware and breakout boards, but the general functionality should match the HC-06 Bluetooth module datasheet. This requires changing the baud rate of the module from the default 9600 to 115200, or 57600, to match the default sketch upload speed for these Arduino boards.ДЄlso, if things are not working, you may want to restore the settings back their defaults and start troubleshooting from there. The HC-05 is a common Bluetooth module used in many microcontroller projects. For example, I am trying to set-up a way to program my Arduino Uno and Arduino Pro Mini wirelessly, over Bluetooth. This Arduino UNO Pinout diagram reference will hopefully help you get the. That works fine, but some applications may require changing the communication speed (Baud rate), the pairing code, the module name etc. Adding a Bluetooth to Arduino can take your project. The HC-05 is an expensive module that is compatible with wide range of devices including smartphone, laptops and tablets. In that example IВ used the Bluetooth module with its default settings. Even though Bluetooth Low Energy Modules available at a reasonable cost, most of these modules are not compatible with existing devices that support the classic Bluetooth.

In a previous post I shared my notes on how to connect an Arduino to an Android phoneВ using the the popular and cheapВ HC-06 Bluetooth module.
