ACR 1252 USB NFC Reader Utils for Android

Utility app for the ACR 1252 NFC Reader. Reads and/or writes various settings:

- Firmware

- Tag polling configuration

- LEDs and buzzer behaviour

Connect the reader via an On-The-Go USB Cable (OTG-USB). If you are using external power, be aware that the connection order (device, reader, power) might be important. For example, my Nexus 5 device requires me to first connect the Android device and the external NFC reader. Then afterwards I can connect the external power. Seeing an USB permissions window that disappears rather quickly is a typical symptom.

The app was built using External NFC Reader Service app, see
