What is Bluetooth hc06?

The HC-06 is a class 2 slave Bluetooth module designed for transparent wireless serial communication. Once it is paired to a master Bluetooth device such as PC, smart phones and tablet, its operation becomes transparent to the user. All data received through the serial input is immediately transmitted over the air.

What are AT commands in Bluetooth?

AT Command Mode. AT command mode allows you to interrogate the Bluetooth module and to change some of the settings; things like the name, the baud rate, whether or not it operates in slave mode or master mode. When used as a master device AT commands allow you to connect to other Bluetooth slave devices.

How do I connect to hc06?

The first thing to do is to power on the Bluetooth module and see if you can connect to it. For this you need an Android device. With the Bluetooth module powered and the LED(s) blinking, on the Android device go to Settings => Connections => Bluetooth and scan for Bluetooth devices. Here the phone has found the HC-06.

What is HC06?

HC06 is a slave Bluetooth device that offers serial communication (UART). Hence, a master is required to establish a successful wireless interface. The module has only communication and power pins. Please note that some HC-06 module may have 6 pins. But only 4 of them are used.

Can HC-06 send data?

HC-06 works on serial communication. 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).

What does AT Command stand for?

ATtention
AT commands are instructions used to control a modem. AT is the abbreviation of ATtention. Many of the commands that are used to control wired dial-up modems, such as ATD (Dial), ATA (Answer), ATH (Hook control) and ATO (Return to online data state), are also supported by GSM/GPRS modems and mobile phones.

How do you use AT commands?

Basic Commands and Extended Commands

There are two types of AT commands:
Basic commands are AT commands that do not start with “+”.
Extended commands are AT commands that start with “+”.
Commands always start with AT (which means ATtention) and finish with a character.
Responses start and end with .

How do I know if my Arduino has Bluetooth?

This works with android phones and the HC-05 and HC-06 bluetooth modules, as well as pretty much any arduino or arduino clone.

Step 1: Connect Module to Arduino.
Step 2: Plug in the Arduino and Upload the Sketch.
Step 3: Connect to the Bluetooth on Your Phone.
Step 4: Connect to the Bluetooth Module.
Step 5: Ready to Go!

How do I connect my Arduino Mega 2560 to Bluetooth?

Baud Rate is set to 9600 Steps:

Install “Bluetooth Terminal” app (By Juan Sebastian Ochoa Zambrano) on Android mobile from Play Store.
Make Physical Connections of the BLuetooth Module (HC-05) as given below.
On Android mobile, Search for Bluetooth and Connect to HC-05 and pair it using password “0000” or “1234”.

How do you identify HC05 and HC06?

Step 1: Identifying Your Module It can be either HC05 or HC06. Both the modules are same in functionality except the pinout. Also HC05 can act as both master and slave whereas HC06 functions only as slave. It’s hard to differentiate between the two only by seeing.

Does Arduino Uno have Bluetooth?

Arduino Uno (or compatible board) A computer with latest version of the Arduino IDE installed. An Android smartphone with Bluetooth capability. JY-MCU Bluetooth Module.

Do you need key pin for hc06 Bluetooth module?

HC06 does not require key pin. Once the module is in AT mode, open arduino. Go to tools>serial port>select the com port your USB to TTL converter is connected to (to find out, go to device manager of your pc>ports (COM &LPT)) .

Is the Arduino compatible with the hc-06 module?

Arduino and HC-06 (ZS-040) The HC-06 is a slave only BT module that is fairly easy to use with the Arduino using serial communication. Once it is connected it simply relays what it receives by bluetooth to the Arduino and whatever it receives from the Arduino it sends to the connected device.

How to change the name of the HC05 module?

For HC05: Type “AT” (without the quotes) on the serial monitor and press enter. if “OK” appears then everything is all right and the module is ready to take command. Now you can change the name of the module]

How to connect HC05 Bluetooth module to ground?

For HC05: Connect the Rx pin of the Bluetooth module to Tx pin of USB to TTL converter, and Tx pin of Bluetooth to Rx pin of converter. Also connect their ground but don’t connect the Vcc yet. First you’ll have to short the key pin with the Vcc.
