The HC-06 is used to add short-range Bluetooth wireless serial communication to Arduino, robotics, IoT, and other microcontroller-based projects.

Is HC-06 a master or slave Bluetooth module?

The standard HC-06 is a slave-only Bluetooth module. A compatible Bluetooth master, such as a smartphone or computer, normally initiates the connection.

What chip is used in the HC-06 Bluetooth Module?

The module described here uses a CSR BC04 Bluetooth chipset. Exact chip and firmware versions can vary between HC-06 module variants.

What is the default baud rate of the HC-06?

The commonly supplied HC-06 module uses a default UART baud rate of 9600 bps, although firmware variants may have different settings.

How does the HC-06 communicate with Arduino?

The HC-06 communicates with Arduino through a UART serial interface using its TXD and RXD pins.

What is the range of the HC-06 Bluetooth Module?

The HC-06 is commonly specified for a communication range of up to approximately 10 meters under suitable conditions. Actual range depends on the environment and connected Bluetooth devices.

Can I control an Arduino robot using an HC-06?

Yes. The HC-06 can receive serial commands from a paired Bluetooth device, allowing it to be used for smartphone-controlled robots and other wireless control projects.

Can I connect the HC-06 to a smartphone?

Yes. A smartphone with compatible Bluetooth Classic support can generally pair with an HC-06 and exchange serial data using a suitable Bluetooth serial application.

What voltage does the HC-06 use?

HC-06 breakout boards are commonly designed for approximately 3.3V to 6V power input, but the exact supply and logic-level specifications depend on the particular breakout-board version.

What are the main pins of the HC-06?

Typical HC-06 boards provide VCC, GND, TXD, and RXD pins. Some versions may include additional status-related pins.

Is HC-06 the same as HC-05?

No. The standard HC-06 is generally configured as a slave-only module, while HC-05 modules commonly support master and slave operating modes.

Where can I buy the HC-06 Bluetooth Module in Bangladesh?

You can buy the HC-06 Bluetooth Module from KathalTech, subject to current stock availability.

Overview

The Arduino Bluetooth Module HC-06 (CSR BC04 Chip) is an easy-to-use wireless serial communication solution for microcontroller projects. It provides a simple way to add Bluetooth connectivity to Arduino and other UART-enabled development boards without requiring a complicated wireless stack in the host controller.

The HC-06 operates as a Bluetooth slave module, making it suitable for applications where a smartphone, computer, or another Bluetooth master initiates the connection. Communication with the microcontroller takes place through a standard UART serial interface, allowing project data, commands, sensor readings, and control instructions to be transmitted wirelessly.

With its integrated PCB antenna and compact breakout-board design, the HC-06 is commonly used in Bluetooth-controlled robots, wireless sensor monitoring, home automation, remote-control projects, and Arduino experiments.

Verified Comments Listing

The HC-06 Bluetooth Module is a widely used wireless serial communication module for Arduino and embedded electronics projects. Based on the CSR BC04 Bluetooth chipset, it provides a straightforward bridge between Bluetooth wireless communication and a microcontroller's UART interface.

Unlike HC-05 modules that can commonly operate in master or slave configurations, the standard HC-06 is generally configured as a slave-only device. A Bluetooth master, such as a smartphone or computer, can pair with the module and exchange serial data with the connected microcontroller.

The module is particularly useful for projects where a wired serial connection needs to be replaced with a short-range wireless link.

Some board variants may expose additional pins such as STATE or status connections.

Important Notes

The HC-06 is normally a slave-only Bluetooth module, so a phone, computer, or compatible Bluetooth master generally initiates the connection.

Although many HC-06 breakout boards include onboard voltage regulation and are marketed for 5V-powered Arduino projects, the actual Bluetooth module uses lower-voltage logic. Verify the specific breakout board's RX/TX logic-level specifications before directly connecting it to a 5V MCU UART.

Bluetooth range can vary significantly depending on antenna orientation, obstacles, interference, and the connected devices.

Module firmware, pairing name, PIN, baud-rate options, and command support can vary between HC-06 production versions.
