Hc 05 Module Bluetooth

Hc 05 Module Bluetooth. It can be used in two modes of operation: Command Mode and Data Mode Slave Mode: In this mode, the module waits for a connection request from a master device, such as a smartphone, laptop, or another Bluetooth-enabled device.

Before we start with the first example, controlling an Arduino using a smartphone, let's take a closer look at the HC-05 Bluetooth module Comparing it to the HC-06 module, which can only be set as a Slave, the HC-05 can be set as Master as well which enables making a communication between two separate Arduino Boards.

You can use this module to communicate between two microcontrollers like Arduino or communicate. However, it does not support some of the advanced features of the HC-05, such as the ability to enter AT mode to configure the module. The HC-05 Bluetooth Module can be used in two modes of operation: Command Mode and Data Mode

. It communicates with Arduino using Serial Communication (UART), making it easy to connect with Arduino's TX and RX pins. Data Mode transforms the HC-05 module into a transparent data gateway

. In AT Mode, users can adjust various settings of the HC-05 module, such as its name, baud rate, PIN code, and data rate. The HC-05 is a popular module which can add two-way (full-duplex) wireless functionality to your projects
