xbee-serial-server

Release 0.9.1 is in Maven Central

Connects to an xbee radio on port specified by arg[0] at 9600 baud and listens on port 10010 for connections. This simply relays all TX packets to the radio and forwards RX packets to socket clients. Use with https://github.com/andrewrapp/xbee-api

Example:

Start the server on machine that has attached XBee radio. In this case the XBee is exposed on serial port /dev/ttyUSB0. Note: RXTX must be added to classpath and java.library.path.

java -Xms16m -Xmx64m -Djava.library.path=/usr/lib/jni/ -classpath "*:/usr/share/java/RXTXcomm.jar" com.rapplogic.xbee.serialserver.server.XBeeSerialServer /dev/ttyUSB0 

Then, somewhere else on the network, start the client and specify the host and port of the server. All XBee commands will now be sent over the wire.

XBee xbee = new XBee(new XBeeConfiguration().withStartupChecks(false));
// connect to xbee-serial-server on host "pi" with port 10010
xbee.initProviderConnection((XBeeConnection)new SocketXBeeConnection("pi", 10010));
AtCommandResponse response = (AtCommandResponse) xbee.sendSynchronous(new AtCommand("AI"));
System.out.println("Received AI response " + response);
xbee.close();
