The Simplex is a type of unidirectional transmission in which the Rx cannot respond to the Rx.

There are three types of relations between the master and the slave from the point of view of the Tx and Rx (Transmitter and Reciever) the Simplex, the Full Duplex and the Half Duplex. There are many different communications but, in this one, the master is typically located in the center along with the RS-485 cable set, and two slaves are located at the physical end of the wires, making the terminations. Usually, when we talk about a master-slave arrangement, the master device initiates all the communication activity, providing itself the bias.
SerialPort ubxPort = ports // instead of i use the port that is available. (" " + ports.getSystemPortName() + ": " + ports.getDescriptivePortName() + " - " + ports.getPortDescription()) ("\nUsing Library Version v" + SerialPort.getVersion()) Try this first to see if you can find your ports first. In your code, you get ports 2 times, I suggest to use the example of JSerialComm defining the ports. Whenever i want to work with serial ports, i always first check that i could define my ports correctly before writing data to it. If (incomingByte != -1) // -1 means no data is available
IncomingByte = Serial.read() // read the incoming byte:

#Arduino mega serial port code#
Here is my code in the Java part and the Arduino part. Here the things, I send the data to the card by the port: /dev/cu.usbmodem1411 so i put this portdescription in the method: SerialPort.getCommPort("/dev/cu.usbmodem1411") but everytime i use the method: sp.openPort() i can't open the port. I use the usb cable to connect the arduino. I am working on a project in internship and i have some issues for trying to cummunicate a Java Programme to a Arduino Mega 2560 while using the librairie jSerialComm.
