Bluetooth SPP & BLE – Wireless Communication and Control

Bluetooth SPP & BLE is an Android application designed to communicate with, control, and monitor electronic devices using Bluetooth Classic (SPP) and Bluetooth Low Energy (BLE).

It is an ideal tool for students, technicians, engineers, developers, and electronics enthusiasts working with Arduino, ESP32, STM32, robotics, automation, and embedded systems.

MAIN FEATURES

• Terminal Mode

Sends and receives data via Bluetooth in real time. Ideal for serial communication, sensor reading, command sending, and diagnostics and debugging of electronic projects.

Allows customization of the colors of sent and received data.

• Control Mode

Controls robots, vehicles, and other devices using directional buttons and configurable commands.

Includes automatic sending of the stop command when the buttons are released, facilitating motion control.

• On-Off Mode

Activates and deactivates electronic devices using power buttons.

Ideal for controlling LEDs, relays, lights, and other digital outputs of a microcontroller.

• RGB Palette Mode

Select colors using an interactive circular palette or individually adjust the red, green, and blue (RGB) components.

Allows you to send the selected color to compatible devices, simplifying RGB lighting projects and LED control.

• Bluetooth SPP and BLE Connection

Searches for, identifies, and selects nearby Bluetooth devices.

Supports working with classic Bluetooth via the SPP profile and with BLE devices that use compatible GATT services and features.

• Customization

- Light and dark themes.

- Configurable colors for the terminal.

- Intuitive and easy-to-use interface.

- Help section for the main functions.

• Multilingual Support

Available in Spanish, English, and Portuguese.

IMPORTANT INFORMATION

Compatibility depends on the Bluetooth protocol, available services, firmware, and configuration of each device.

Not all BLE devices support direct serial communication. Device detection does not guarantee that it can exchange data with the application.

Bluetooth SPP & BLE requires a Bluetooth-enabled Android device and the necessary permissions to discover and connect devices.

Turn your Android device into a Bluetooth communication and control tool for your electronics projects.
