Programming Linux serial ports in Java


1 month ago

We are looking for a Java developer familiar with communication via serial ports. We need to develop some functionalities on the Raspberry Pi server. The server communicates with PLC devices through GSM/LTE modems. Modems are connected to the server via RS232 or RS485 serial interfaces. The software collects data from PLCs with MBus, Modbus or DLMS.

We need to run our software with modems connected to HATs which provide RS232/485 via SPI driver. The system is written in Java. So knowing Java is a must-have.
