How It Works
The BT (Bluetooth) module functions as a wireless UART bridge. It replaces a physical serial cable between two devices with a Bluetooth wireless link. The module receives serial data on its RX pin from your microcontroller, transmits it wirelessly over Bluetooth to a paired device, and vice versa. When powered on, the module enters discoverable mode, allowing smartphones or other Bluetooth devices to find and pair with it using a default PIN (typically 1234 or 0000). Once paired, the connection is transparent - any data sent to the module's serial input appears at the paired device's serial output, enabling real-time bidirectional communication. Configuration is done by entering AT command mode, where you can change the device name, PIN code, baud rate, and operational role.
Pin Configuration
| Pin | Label | Function |
| 1 | VCC | Power supply input (3.3V - 5V DC) |
| 2 | GND | Ground connection |
| 3 | TX | Serial data transmit (connect to MCU RX) |
| 4 | RX |
