Bluetooth Classic tutorial: https://www.youtube.com/watch?v=TtpLcsQ4nMw Works with HC-06 or HC-05 modules. Other Bluetooth classic modules should work too. Bluetooth LE tutorial: https://www.youtube.com/watch?v=zRJctDUt-Zg

Works with JDY-08 module. For other Bluetooth LE modules, you need to modify UUIDs of service and characteristic which has read and write descriptor. It is located in BluetoothLeService.java file.

For RFID I have used this library, which I have modified: https://github.com/soonuse/pn532-lib/blob/master/examples/stm32/stm32.7z RFID project example uses PN532 to read UID from RFID card and then send it as a string to the Android app via Bluetooth.
