This is a Matter Controller Kotlin app that can be used to commission and control Matter accessory devices.
You need to have the following two software installed on your Ubuntu system:
- Java Runtime Environment (JRE)
- Java Development Kit (JDK)
openjdk version "11.0.20.1" or above is needed
First, check if we have the Java Runtime Environment and Java Development Kit installed on our system or not.
java -version
If not, you can install the Java Runtime Environment and Java Development Kit on your system through the following command as root:
sudo apt install default-jre
sudo apt install default-jdk
You also need to install kotlin compiler on your Ubuntu system:
kotlin compiler version 1.8.10 or above is needed to compile
kotlin-matter-controller, if you already have lower version kotlin compiler
installed on your Ubuntu from apt,
you need to remove the Kotlin compiler package, run the following command:
sudo apt-get remove kotlin
Wait for the removal process to complete. Once it's done, the Kotlin compiler will be removed from your system.
(Optional) If you want to remove any configuration files associated with Kotlin, run the following command:
sudo apt-get purge kotlin
Install kotlin compiler 1.8.10 or above, such as kotlin-compiler-1.8.10-url
cd /usr/lib \
&& sudo wget -q [kotlin-compiler-1.8.10-url] \
&& sudo unzip kotlin-compiler-*.zip \
&& sudo rm kotlin-compiler-*.zip \
&& sudo rm -f kotlinc/bin/*.bat
Add a directory to PATH permanently by editing the .bashrc
file located in the
Home directory. Follow these steps:
- Open the
.bashrc
file using a text editor. - Go to the end of the file.
- Paste the export syntax at the end of the file.
export PATH="/usr/lib/kotlinc/bin:$PATH"
export JAVA_PATH=[JDK path]
Complete the following steps to prepare the Matter build:
-
Check out the Matter repository.
-
Run bootstrap (only required first time)
source scripts/bootstrap.sh
This is the simplest option. In the command line, run the following command from the top Matter directory:
./scripts/build/build_examples.py --target linux-x64-kotlin-matter-controller build
The Java executable file kotlin-matter-controller
will be generated at
out/linux-x64-kotlin-matter-controller/bin/
Run the kotlin-matter-controller
java -Djava.library.path=../lib/jni -jar kotlin-matter-controller
