McuBleTerminal is a Bluetooth Low Energy terminal app designed for ESP32 development. It allows you to view serial output and send text commands wirelessly from your smartphone. No USB cable, no drivers, no WiFi and no cloud services required. The app works together with the McuBleTerminal ESP32 library and acts like a classic serial monitor, but over BLE. Typical use cases include debugging, viewing sensor data, testing firmware behavior and interacting with ESP32 devices while they are powered in real environments. Features include a clean terminal interface, monospace font, dark and light mode support, multilingual UI and a built in demo mode that works without any hardware. This app is intended as a development and debugging tool. ESP32 library and examples are available on GitHub: https://github.com/dominik-ewers-solutions/MCU_BLE_Terminal
