This repository contains additional documentation for Calimero and code examples using Java and Kotlin.

All examples require Java 11 and can be built using Gradle (./gradlew build). A single example can be executed via Gradle by specifying the class like ./gradlew run -DmainClass=GroupMonitor.

For Kotlin, an example can be run via Gradle by appending "Kt" to the class name, e.g., for DiscoverKnxServers this would be ./gradlew run -DmainClass=DiscoverKnxServersKt

• Discover KNXnet/IP servers
• Discover KNX USB devices
• Create client-side KNXnet/IP tunneling network link
• KNX IP Secure routing network link
• Create client-side KNX USB network link
• Create TPUART network monitor link
• Process communication
• Group monitor
• KNX address converter, e.g., ./gradlew run -DmainClass=KnxAddressConverter --args="1/2/3"
• DPT translation
• Network state buffering
• KNX push-button device
• KNX IP push-button device supporting discovery & self description
• LTE device for LTE-HEE runtime communication
• ETS keyring viewer, run it with Gradle using ./gradlew run -DmainClass=KeyringViewer --args="--pwd pwd '/path/to/keyring.knxkeys'"

• Run the example in your IDE, or command line using ./gradlew run -DmainClass=PushButtonDeviceWithDiscovery

• Use process communication to read/write the push button state, for example in the ETS group monitor. Or with the Calimero tools group monitor in a second terminal (./gradlew run --args "groupmon 224.0.23.12") and enter the following commands:

   read 1/0/1 switch
   [response should be printed with switch state off]
   write 1/0/1 on
   r 1/0/1
   [response should be printed with switch state on]
   Ctrl^C

• Read device information of the Calimero KNX device, for example with the ETS device info diagnostics. Or, use the Calimero device info tool ./gradlew run --args="devinfo 224.0.23.12 1.1.10".

• Discover the KNX IP device. With the Calimero discover tool, ./gradlew run -Dexec.args="discover"

  Example output:
