How to connect hc06 Bluetooth to an Arduino?

How to connect hc06 Bluetooth to an Arduino?

The LED on the Bluetooth module should stay on and the app will show “connected: HC-06” . Now send the number 1 through the terminal and the onboard LED on the Arduino should turn on. Send 2 and it should turn off.

How often does Arduino sketch connect to hc-06?

It finds and connects to your “HC-06” without further “human intervention”. And if you turn off the “HC-06”, Android will continue watching for the “HC-06” to come back online, and will auto-connect to it again. The Arduino Sketch sends a signal once each second.

How to check serial number of Arduino module hc-06?

Check the serial number written on the module and the firmware version by entering AT+VERSION. For instance, the module HC-06 labelled ZS-040with firmware version 3.0-20170609 returns ERROR (0) when sending command AT+NAMExxxx (with xxxx the new name of the module).

How to connect hc06 Bluetooth to serial wireless UART?

Select the HC-06 option and then wait a moment. The LED on the Bluetooth module should stay on and the app will show “connected: HC-06” . Now send the number 1 through the terminal and the onboard LED on the Arduino should turn on. Send 2 and it should turn off.

How does the Android app connect to the Arduino module?

The Android app is designed to send serial data to the Arduino Bluetooth module when a button is pressed on the app. The Arduino Bluetooth module at other end receives the data and sends it to the Arduino through the TX pin of the Bluetooth module (connected to RX pin of Arduino).

How is a Bluetooth module connected to an Arduino Uno?

Fig 1. shows the HC-06 bluetooth module diagram. The HC-06 module has four pins which are all required in order to make a connection with the arduino UNO. The VCC pin is where the module receives its input voltage and is thus connected to the 5V pin on the arduino.

Can a hc-06 be connected to a PC?

This is because the HC-06 is a slave Bluetooth device, so your PC must start the communication. On the HC-06 side, you can connect a microcontroller or any other UART capable device. You can configure the HC-06 module before linking the module with your PC. See this postfor more information about the HC-06.

What is the pin for the hc-06 module?

After pairing with the HC-06 module, it will be registered as a “COM” port, and you’ll be able to communicate with it, using any serial port emulator (e.g. qSerialTerm) On the first connection to the module, you’ll be asked for the pin (the default pin is 1234). Inserting the pin on the first connection.

What is the serial port for hc06 Bluetooth?

You can see in line two of the sketch that the software serial port has been defined with the name “BT”, and that any references to the module for serial communication in the sketch are now BT.begin, BT.println and so on.
