How do I program my HC 05 Bluetooth module?
In order to pair the module with your phone, open Bluetooth Settings in your phone and connect to “HC-05” with pin “1234”. If 1234 doesn’t work, try “0000”. Once the Bluetooth Module is paired with your phone, you can start using the App. Open the Bluetooth Controller App and click on scan.
How do I connect my HC 05 Bluetooth module to Arduino?
In order to communicate with HC05 using Bluetooth, you need a Bluetooth terminal application on your phone. You can use this one. Now for start transferring data, upload this code on your Arduino and connect HC05 using the app you have just installed.
How does HC 05 Bluetooth module work?
HC-05 Bluetooth module provides switching mode between master and slave mode which means it able to use neither receiving nor transmitting data. TXD UART_TXD, Bluetooth serial signal sending PIN Connect with the MCU’s (Microcontroller and etc) RXD PIN.
How do I program a Bluetooth module with Arduino?
Open Arduino IDE and go to Tools, then Serial Monitor. Set the Baud rate to 9600 and the ‘line ending’ to ‘Both NL and CR’. Type in ‘AT’ without the quotes and click send. If the Serial Monitor displays “OK”, the module is in AT mode and you are good to go.
How do I connect my HC-05 to my mobile Bluetooth?
Download “Bluetooth Terminal” app from Google Play Store. Open Bluetooth Terminal app. From the menu, tap on “Connect a device – Insecure”. You will see a pop-up of “Paired Devices”, tap on “HC-05”, after a second you will get a toast notifying “Connected to HC-05”.
How do I communicate with Arduino Bluetooth?

What is the working principle of Bluetooth?
Bluetooth works by the simple principle of sending and receiving data in the form of radio waves. Every Bluetooth enabled device has a card-like attachment known as the Bluetooth adapter. It is this Bluetooth adapter that sends and receives data.
What is the purpose of Bluetooth module?
The Bluetooth technology manages the communication channel of the wireless part. The Bluetooth modules can transmit and receives the data wirelessly by using two devices. The Bluetooth module can receive and transmits the data from a host system with the help of the host controller interface (HCI).
What does TX mean on Arduino?
Serial 0 (RX) and 1 (TX) are for receiving (RX) and transmitting (TX) TTL serial data. These pins are connected to the corresponding pins of the ATmega8U2 USB-to-TTL Serial chip. The RX and TX LEDs on the board flashes when data is being transmitted via the USB-to-serial chip and USB connection to the computer.
How do I connect my HC 05 to my computer?
To make a link between your Arduino and bluetooth , do the following :
- Go to the bluetooth icon , right click and select Add a Device.
- Search for new device , Our bluetooth module will appear as HC-05 , and add it.
- The pairing code will be 1234 .
What is HC05 Bluetooth module?
HC05 module is a Bluetooth module using serial communication, mostly used in electronics projects. HC05 Bluetooth module important specifications: Working voltage: 3.6V – 5VInternal antenna: YesAutomatic connection to the last device: Yes Sending Data to Arduino via Bluetooth
How to send data from HC05 to Arduino via Bluetooth?
Sending Data to Arduino via Bluetooth. HC05 module has an internal 3.3v regulator and that is why you can connect it to 5v voltage. But we strongly recommend 3.3V voltage, since the logic of HC05 serial communication pins is 3.3V.
How do I connect the hc-05 to the computer?
It simply connects the computer terminal and the HC-05 in a loop. The codes sends the messages from the terminal to the Bluetooth Module and messages from the Bluetooth module to the terminal. #include SoftwareSerial EEBlue (10, 11); // RX | TX
How do the Bluetooth codes work?
The codes sends the messages from the terminal to the Bluetooth Module and messages from the Bluetooth module to the terminal. EEBlue.begin(9600); //Default Baud for comm, it may be different for your Module.
