recordingStream = Connection.getInputStream(); for (int i = 0; i < 1; i++) { // 1 раз 1 байт. if (recordingStream.read(buffer, 0, ikk) != -1 && isRecording) { //writer.write(buffer, 0, ikk); String lin = new String(buffer, 0, ikk); //из потока в String(?) прочитался один байт - ikk=1 } }

Next you need to read lin and output it hex (hex there is: 04 Here is 04 and you need to read it in the next String as text).

Simply put, decode one byte from hex into text.

     String inputString = lin; byte[] byteArray = inputString.getBytes(); String xx = Arrays.toString(byteArray); char my = xx.charAt(1);

    Total: my = 4 That is necessary. Lucky day. But in my opinion is not ergonomic.
