The HC-06 Bluetooth Module is a simple, low-cost, and widely used module for wireless serial communication. Unlike the HC-05, the HC-06 only works in Slave mode, meaning it can receive connections from a master device (like a smartphone, laptop, or HC-05 module), but it cannot initiate connections itself.
๐น Key Features
Bluetooth version: 2.0 + EDR (Enhanced Data Rate).
Operating Voltage: 3.3V โ 6V (internally regulated to 3.3V, safe to power with 5V).
Current consumption: ~30 mA during data transmission.
Communication: UART (TX, RX).
Default Baud Rate: 9600 bps.
Range: ~10 meters (Class 2).
Default Name: "HC-06".
Default Password: 1234 or 0000.
Modes: Slave only (cannot act as Master).
๐น Pin Configuration
VCC โ Power supply (3.6V โ 6V, typically 5V).
GND โ Ground.
TXD โ Transmit data pin (connects to RX of Arduino).
RXD โ Receive data pin (connects to TX of Arduino, but needs 3.3V logic).
(Some versions have a STATE pin for connection status, but itโs optional.)
๐น How It Works
When powered, the HC-06 waits to be discovered by another Bluetooth device.
A smartphone, PC, or another master module can pair with it.
Once paired, it works as a wireless serial link, just like a wired UART connection.
Whatever data is sent from the Arduino via TX will be received on the paired device, and vice versa.
๐น Applications
Wireless communication with microcontrollers (Arduino, ESP32, PIC, STM32).
Bluetooth-controlled robots and cars.
Wireless data logging from sensors to a smartphone/PC.
Home automation (controlling lights, fans, or appliances).
Replacing USB/Serial cables with a wireless link.
