This setup shows how an Andriod application starts on detection of an NFC tag, and quits if the tag is not present anymore. The tag emulator (STM32 microcontroller) receives the servo position from the Anroid app and sends the state of 3 buttons to the app.
In this way a lot of things are possible “on the fly”. It´s a very easy handling without pairing (like Bluetooth). The speed is comparable with a UART @38400 baud.
