Serial Bluetooth Terminal

Serial Bluetooth Terminal is a powerful line-oriented console app that bridges your Android device to microcontrollers, Arduino boards, and embedded systems via Bluetooth connection. Connect wirelessly to any serial or UART device using a Bluetooth-to-serial converter and communicate instantly from your phone or tablet.

Whether you're prototyping with Arduino, debugging embedded firmware, or building IoT applications, this app gives you direct terminal access to your hardware. You'll gain instant two-way communication with your devices without needing a computer—ideal for field testing, configuration, and real-time monitoring.

The app supports both Bluetooth Classic and Bluetooth Low Energy (BLE), making it compatible with the widest range of devices. Connect to industry-standard modules including HC-05, HC-06, Raspberry Pi 3, BBC micro:bit, Texas Instruments CC254x series, Nordic nRF51822, Microchip RN4870/71, Silabs BLE113, and many others. You can also use custom Bluetooth GATT profiles for specialized hardware.

Everything you need is completely free—all core features are included at no cost. There's no paywall separating you from your devices. The only optional in-app purchase is a voluntary donation feature to support development.

Serial Bluetooth Terminal is perfect for makers, engineers, students, and hobbyists who need reliable wireless debugging and terminal access. Download it now and start communicating with your microcontroller projects directly from Android.
