MCU BLE Terminal

McuBleTerminal is a simple and powerful BLE terminal app for ESP32 microcontrollers.

It allows you to view serial output such as print, println or printf wirelessly over Bluetooth Low Energy, without USB cables, WiFi or cloud services.
Perfect for debugging, logging, sensor output and simple command input directly from your smartphone.

The companion ESP32 library is designed as a drop in replacement for Serial and requires only minimal code changes.
A built in demo mode lets you try the app without any hardware.
