The HC-05 Bluetooth Module is a compact and low-cost wireless serial communication module that enables Bluetooth connectivity for microcontroller-based projects. Based on the CSR BC417 Bluetooth chipset, it supports the Bluetooth V2.0 + EDR (Enhanced Data Rate) specification and communicates using the Serial Port Profile (SPP), allowing transparent wireless serial data transmission between devices. The module can operate in both Master and Slave modes, making it suitable for establishing communication with smartphones, computers, and other Bluetooth-enabled devices.

Operating from a 3.6V to 6V DC supply, the HC-05 communicates with microcontrollers via a standard UART interface. It supports configurable baud rates, AT command configuration, and features an onboard antenna for reliable wireless communication over distances of up to 10 meters under typical conditions. Compatible with Arduino, ESP32, STM32, Raspberry Pi, PIC, AVR, and other embedded platforms, the HC-05 is widely used in robotics, home automation, wireless control systems, IoT devices, and educational electronics projects.

FAQ

1. What is the HC-05 Bluetooth Module used for?

The HC-05 Bluetooth Module is used to add wireless Bluetooth serial communication to microcontroller projects. It is commonly used in robotics, home automation, IoT devices, wireless data transfer, and smartphone-controlled applications.

2. Can the HC-05 operate as both Master and Slave?

Yes. The HC-05 supports both Master and Slave modes. It can be configured using AT commands, allowing it to either initiate a Bluetooth connection or accept incoming connections.

3. Is the HC-05 compatible with Arduino and ESP32?

Yes. The HC-05 is compatible with Arduino, ESP32, STM32, Raspberry Pi, PIC, AVR, and other UART-enabled microcontrollers. When connecting to 5V systems, the RX pin should ideally be driven through a voltage divider or logic level converter.

4. What are the default settings of the HC-05 module?

The factory default settings are typically Device Name: HC-05, Pairing PIN: 1234 (or 0000 on some versions), Data Mode Baud Rate: 9600 bps, and AT Command Mode Baud Rate: 38400 bps.

5. Can the HC-05 communicate with smartphones?

Yes. The HC-05 supports the Bluetooth Serial Port Profile (SPP) and can communicate with most Android smartphones, PCs, and other Bluetooth Classic devices. It is not directly compatible with iPhones or iPads, as iOS does not support SPP for third-party Bluetooth Classic modules.
