If you want to use the built-in UARTs to communicate directly with a device connected via GPIO header, you will need to tell RXTX about your port using the gnu.io.rxtx.SerialPorts property. dev/ttyUSBx), but won’t enumerate ports using other names. RXTX automatically scans for serial ports using known-conventions for various platforms and will automatically detect standard serial ports (ie. ![]() See Shell Scripts below for one possible solution. Instead, set the property at run time: java =/usr/lib/jni ĭepending on your application, changing the library path may have other consequences, so you may want to set this only on some platforms. The library path can be set in code, but since the goal of Java is to ensure portability, it probably doesn’t make sense to hard-code paths into applications. This path is automatically included in the Java Library Path on some platforms, but not all, so you need to update this property. This installs librxtxSerial.so in /usr/lib/jni. Native LibrariesĪfter install the JRE, RXTX native libraries also need to be installed: sudo apt-get install librxtx-java ![]() dev/ttyO1, /dev/ttyAMA0), need to do a bit of setup before things will work as expected. ![]() Java developers and applications that access serial ports with RXTX on a Raspberry Pi, Beaglebone Black, or similar debian-based platform using non-standard serial port names (ie.
