This project is targeted to use RFXCOM device from Java environment

The aim is to be able to use RFXCOM devices (as RFXtrx433E devices in a java environment).

This project is firstly design to be use in Linux Raspberry Pi java context. This Project exist because default RFXCOM public provided tools is targeted for Windows(r) environment.

There is no Java native library dependency, the project invokes standard linux command instead (mkfifo, stty ...) to be able to configure and use the serial port, by this way the program is directly runnable everywhere without any architecture limitation. Therefore the target is "Only Linux alike system, enabled with USB FTDI serial port device, and a Java JVM available"

Install and Run on PI or other Linux machine

Environment

• Java + Javac: Oracle or OpenJDK 1.8
• Kernet module for FTDI USB devices (RFXCOM device seen as /dev/ttyUSBx (with x above or equal to 0)
• User is able to access to /dev/ttyUSBx (e.g user has secondary group on 'dialout')

Get project

Clone this project on a dedicated folder on you Raspberry Pi or Linux Machine In this project all compiled class are already provided in build folder.

Configure

if your device is not /dev/ttyUSB0 then you need to change the file config.properties To enable the listening of particular protocol you've to modify the file config.properties , the key rfxtrx.protocol.enable

Compile project

Execute (this project already provide the compiled classes, compilation is needed only if you change the source code)

./compile.sh

Execute project

Direct mode

./run.sh

Simple daemonized mode

nohup ./run.sh 1>trace.log 2>&1

Use the project

During execution the project has an input and an output

The Input : Send a message over the air

When the project runs, a named pipe pipeMsgSend is created by default at the same location as the config.properties file. To send a message over the air (through RFXCOM device) just print out the command to pipeMsgSend example, to Switch On a Chacon power plug on House 'I' address 1

$> echo "chacon_on('I',1)" > pipeMsgSend

The available commands are defined in extension.js file The base command library is defined in file src/ysm/domo/rfxcom/rfxtrx/protocol/generateMessage.js

The Output : Execute something when a message is received

When a message is recieved for a particular protocol enabled (see key rfxtrx.protocol.enable in config.properties) then the script event.sh is invoked with a set of RFXCOM_* environment variables You may customized the event.sh script with your own purpose or change the keys rfxtrx.protocol.event.* in config.properties file to execute another shell script or executable
