Prerequisites
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) A Welcome Wizard will guide you thru the setup process.
(Re) 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[edit]
Connection refused[edit]
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[edit]
If you get the following error message on OpenJDK:
java -jar can4eve.jar
Exception in thread "main" java.lang.NoClassDefFoundError: javafx/event/EventHandler
at java.lang.ClassLoader.defineClass1(Native Method)

fix for Raspberry PI[edit]
If on a Raspberry PI you get the message java.lang.NoClassDefFoundError: javafx/application/Application>
get the SDK from: http://gluonhq.com/products/mobile/javafxports/get/
cd /usr/local/src
sudo wget http://download.gluonhq.com/javafxports/embedded/armv6hf-sdk-8.60.9.zip

java.net.BindException: Address already in use (Bind failed)[edit]
There is probably another instance of can4eve already running. In rare cases another application might use the same port as can4eve.
java.net.SocketException: Network is unreachable (connect failed)[edit]
At the network address and port you selected there was no connection possible. Please check the settings and the network device you'd like to connect to. E.g. you can do a ping to the network address and try a telnet to the given port. see Help/NetworkConnection
com.bitplan.elm327.OBDException[edit]
Their has been a problem with the OBD connection. The most common error is a timeout which might e.g. happen if you set the wrong baud rate or the device is not listening e.g. because it went to sleep.
java.net.ConnectException: Connection refused (Connection refused)[edit]
The network is reachable at the address but not the port you specified.\nYou might want to check the network device and the settings. see Help/NetworkConnection
File descriptor is -1 < 0,[edit]
INFORMATION: purejavacomm.PureJavaIllegalStateException: File descriptor is -1 < 0, maybe closed by previous error condition
The OBDII-Adapter is not properly connected or there is another issue with the connection.
