This snippet reads a message from a bluetooth device and converts it content into a String object

ReadFromBluetooth.java

public void run() {
  StringBuilder sb = new StringBuilder();
  
  while (true) {
    try {
      byte[] buffer = new byte[1024];
      int bytes;
      int bytesRead = -1;
      
      do {
        bytes = mmInStream.read(buffer, bytesRead+1, 1);
        bytesRead+=bytes;
      } while(buffer[bytesRead] != '\n');
      
      Log.i("Log info:", new String( Arrays.copyOfRange(buffer, 0, bytesRead-1)));
      sb = new StringBuilder();
    } catch (IOException e) {
      e.printStackTrace();
      break;
    }
  }
