How do you communicate with HC-05?

Table of Contents

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.

What is difference between HC-05 and hc06?

Hc-05 is a Bluetooth serial port module with master-slave integration. The master-slave can be switched with rich and complete instructions. Hc-06 is a Bluetooth serial port module with master-slave integration. The master-slave can be switched by command, and the command is less than the-05, so it is easy to use.

Can HC-05 send data?

The HC-05 module can be operated within 4-6V of power supply. It supports baud rate of 9600, 19200, 38400, 57600, etc. Most importantly it can be operated in Master-Slave mode which means it will neither send or receive data from external sources.

Is Bluetooth two way communication?

You likely use Bluetooth as a two-way connection between your smartphone and your favorite set of wireless earphones, one that allows you to stream audio and send simple control commands—like skipping audio tracks, or answering/ending phone calls—between one and the other.

How does Bluetooth module HC-05 work?

HC-05 has red LED which indicates connection status, whether the Bluetooth is connected or not. Before connecting to HC-05 module this red LED blinks continuously in a periodic manner. When it gets connected to any other Bluetooth device, its blinking slows down to two seconds. This module works on 3.3 V.

Can 1 Bluetooth connect to multiple devices?

Bluetooth headphones and speakers can’t connect with multiple devices at a time. Just think of how making multiple phone calls to multiple devices at once is not possible. If your headphones are already connected to one mobile device, they cannot be simultaneously connected with another mobile device.

How to configure hc-05 Bluetooth module in configuration mode?

Connect HC-05 Bluetooth Module in configuration mode: Arduino Mega -> BluetoothModule Pin0 (Rx0) -> Rx Pin1 (Tx0) -> Tx Gnd -> GND Vcc -> VCC (+5V) 3.3V -> Pin 34 Serial Communication through USB cable (Tx0 and Rx0) to Arduino Terminal (Desktop) is used just to cross verify. Enter into configuration mode:

What are the commands for the hc-03 and hc-05?

The most common commands for HC-03 and HC-05 are: AT+ROLE (set master –slave), AT+CMODE ( set address pairing) , AT+PSWD (set password). If you want the master module has the function of remembering slave module, the most simply way is: First, set AT+CMODE=1.

How do I wire my hc-05 to my computer?

If for some reason your HC-05 does not have a button or the button is not working you can wire as shown: EN >> 3.3v If your Bluetooth module does have a button all you have to do is to remove the EN pin from 3.3v. Now before you plug in the power cable hold the button and then plug it in.
