Bluetooth Commander is a specialized Bluetooth terminal app designed for Android smartphones. Its primary purpose is to facilitate low-level communication between your device and various Bluetooth-enabled hardware, such as Arduino boards, microcontrollers, processor boards, or other Bluetooth modules. Unlike many conventional apps, Bluetooth Commander allows you to connect to multiple devices simultaneously while giving you powerful diagnostic tools and a command database editor for personalized control.

As of version 6.8 (currently in beta testing), the app introduces an exciting new feature—using your phone’s built-in sensors. This means data such as GPS location, acceleration, temperature, battery level, and proximity can be seamlessly integrated into custom commands and transmitted to connected devices. This opens up new possibilities for automation, robotics, IoT projects, and more.

Key Features of Bluetooth Commander

Multi-Device Connections

One of the strongest features of Bluetooth Commander is its ability to establish and maintain communication with multiple Bluetooth devices simultaneously. Whether you are working with classic SPP modules or modern Bluetooth Low Energy (BLE) devices, the app can handle both, even in parallel connections.

Flexible Interface Options

Bluetooth Commander offers three different layouts to suit different usage scenarios:

• List Layout – The default and simplest mode, where commands are organized in a scrollable list.
• Gamepad Layout (BETA) – Designed for real-time control of moving devices, such as robots, drones, or any hardware with directional or mechanical movement.
• Custom Layout (BETA) – A fully customizable interface where you can design your own control panel according to your project’s requirements.

Command Creation and Editing

The app features a powerful command editor, enabling you to create and manage commands in both hexadecimal and text formats. With a simple tap, you can send these commands instantly, ensuring smooth and efficient communication.

Advanced Communication Options

Bluetooth Commander also includes periodic transmission tools, letting you send commands automatically at defined intervals. This is especially useful for continuous monitoring or automated testing. Additionally, the app comes with advanced logging functions, offering color-coded logs, timestamps, and the ability to track communication across multiple devices.

Supported Bluetooth Device Types

Bluetooth Commander is compatible with a wide range of Bluetooth technologies, making it ideal for both hobbyists and professionals. The supported devices include:

• Classic Bluetooth (SPP – Serial Port Profile)
• Bluetooth 4.0 and newer (Low Energy / Smart Bluetooth)

What sets this app apart is the ability to connect both SPP and BLE devices at the same time, enabling seamless integration of old and new hardware within a single workflow.

Interface Layouts in Detail

Basic List Layout

The default layout is a straightforward list-based interface. Here, you’ll find a connection panel at the top and a customizable logging area at the bottom, making it easy to monitor commands and responses in real time.

Gamepad Layout (BETA)

The gamepad layout is tailored for interactive control, particularly suited for robotics or devices requiring directional input. You can assign buttons to specific commands, giving you intuitive control over movement, arm positions, or orientation adjustments.

Custom Layout (BETA)

For advanced users, the custom layout allows full freedom to design a personalized control panel. You can arrange buttons, sliders, and command interfaces however you wish, tailoring the setup to perfectly match your specific project.

Switching between layouts is simple: just tap the menu button → Switch layout.
