Me and a friend are trying to develop an app which sends temperature calculated by the Nexys4 FPGA board sensor to an Android app developed in Android Studio using Java. The temperature is calculated correctly, our app connects to the Bluetooth Pmod BT2 module but the problems occur when we try to send data to our app. I attached below the files we used including the BluetoothActivity file where the receiver is implemented. We would be very happy if you could tell us what is the problem. Thank you!!!
