![]() ![]() If you send AT from serial monitor, OK will appear on the screen. The connection between the bluetooth module and Arduino is just a normal serial comunication where we connect the Rx pin of the module to the Tx pin of the. Be sure that the baud rate is set to 9600 and Both NL & CR are selected. If (Serial.available()) // Keep reading from Arduino Serial Monitor and send to HC-05 If (BTSerial.available()) // read from HC-05 and send to Arduino Serial Monitor ![]() Here is how you should connect the Bluetooth module to your Arduino. Right now I will only deal with 4 pins, which are VCC, GND, TXD and RXD. Raspberry Pi and Arduino bluetooth communication. The HC-06 has 6 pins: wakeup, VCC, GND, TXD, RXD and State. This is my Arduino code where connected with raspberry pi3 and it receives RF value from other RF. All you need to know is the pin configuration. SoftwareSerial BTSerial(5, 6) // RX | TXīTSerial.begin(38400) // HC-05 default speed in AT command more Step 1: Setup Setting up the HC-06 is as easy as ABC. The long(2seconds) slow blinks show that we are in AT Command mode. Make the following circuit with the help of the below-mentioned components.Īfter the connection, If you Plug the power source, you will see the HC-05 power on with short rapid blink, which is the standard pairing mode of the module.įor At Mode, you need to plug the power source while holding down the reset button on the module. These are very helpful in creating wireless low-energy projects. Don't forget to visit my website for circuit diagrams, code downloads. These add-on cards help you enable the Arduino UNO’s Bluetooth option. to show the Arduino talking to your phone over the Bluetooth link. ![]() HC-05, HC-06, and HM-10 are a few examples. You can connect Arduino to a Bluetooth link using add-on cards. Before making the connection make sure to unplug the power source from Arduino UNO. How do I connect Bluetooth to Arduino There is no Bluetooth on the Arduino UNO. ![]()
