Serial Input Buffer Size November 7, 2017
Make sure that the Serial Input Buffer Size is adequate for your application. It is 128 bytes by default. If a greater number of bytes that the buffer size are sent and your application does not read them in time then the buffer can fill and data will be lost.
// display the current buffer size System.out.println("auxSerialPort.getInputBufferSize(): " + auxSerialPort.getInputBufferSize()); // set the new buffer size auxSerialPort.setInputBufferSize(256); // display the new buffer size System.out.println("auxSerialPort.getInputBufferSize(): " + auxSerialPort.getInputBufferSize());
The output should look as follows.
auxSerialPort.getInputBufferSize(): 128 auxSerialPort.getInputBufferSize(): 256
