Prerequisites

Oracle Java Runtime 8

or if you'd like to build can4eve yourself:

Installation

Download the software for your platform from Downloads

or build the software yourself

Starting

Run the software with java -jar can4eve.jar or can4eve (If you built the software yourself: cd can4eve/obdii/release before this command) The first screen should show one of the Panels shown below.

Configuring your OBD connection

Select the menu Settings/OBDII

Network connection: Select the deviceType Network, set the hostname and port
USB connection: Select the deviceType USB, select the serialDevice via the "..." button near the serialDevice, set the baudRate (only click direct if you are setting the baudrate via a different means e.g. stty)
Bluetooth connection: Not directly supported as of 2017-07 - you might want to e.g. use the OBDLink_LX#Forwarding the OBDII Adapter via TCP/IP or forward via can4eve options
Simulator connection: Select the deviceType simulator

Click "testConnection". The result should be e.g.:

Now you should be able to use the Menu OBD/Start or OBD/Start withLog.

Troubleshooting

Connection refused

If you get the message "Connection failed", "ConnectException: Connection refused(Connection refused)". You might want to check the hostname and port settings. Also you can tryout the connection e.g. on a command line.

See e.g. VGate_ICar_2#Testing

NoClassDefFoundError: javafx/event/EventHandler

If you get the following error message on OpenJDK:

You might want to follow the following instructions:

That is

sudo apt-get install openjfx

or on Raspberry PI

sudo apt-get install openjdk-8-jdk

java.net.BindException: Address already in use (Bind failed)

There is probably another instance of can4eve already running. In rare cases another application might use the same port as can4eve.
