+# Matter BEKEN Lighting Example
+
+This example demonstrates the Matter Lighting application on BEKEN platforms.
+
+---
+
+-   [Matter BEKEN Lighting Example](#matter-BEKEN-lighting-example)
+    -   [Supported Devices](#supported-devices)
+    -   [Building the Example Application](#building-the-example-application)
+    -   [Commissioning over BLE using chip-tool](#commissioning-over-ble-using-chip-tool)
+
+---
+
+## Supported Devices
+
+The demo application is intended to work on following categories of BEKEN
+devices:
+
+- BK7235 EVB
+
+## Building the Example Application
+
+Building the example application requires the use of the BEKEN ARMINO IoT
+Development Framework ([BK-ARMINO](https://github.com/zhengyaohan/armino)).
+
+-   Setting up the build environment, recommended with Ubuntu 20.04 LTS
+
+    Armino sdk download
+
+        $ cd ~ 
+        $ git clone [email protected]:zhengyaohan/armino.git
+        $ git checkout matter
+
+    Toolchain [download](http://dl.bekencorp.com/tools/toolchain/risc-v_20220418.tar.gz)  and install, the toolchain should be installed to "/opt/risc-v"
+
+        $ sudo tar xvzf {abs-path-to-download}/risc-v_20220418.tar.gz -C /opt
+        $ sudo mv /opt/risc-v_20220418 /opt/risc-v
+        $ sudo chown -R $USER:$USER /opt/risc-v
+
+
+    Software dependency install
+
+        $ sudo dpkg --add-architecture i386
+        $ sudo apt-get update
+        $ sudo apt-get install build-essential cmake python3 python3-pip doxygen ninja-build libc6:i386 libstdc++6:i386 libncurses5-dev lib32z1 -y
+        $ sudo pip3 install sphinx_rtd_theme future breathe blockdiag sphinxcontrib-seqdiag sphinxcontrib-actdiag sphinxcontrib-nwdiag sphinxcontrib.blockdiag
+        $ sudo ln -s /usr/bin/python3 /usr/bin/python
+
+    To activate connectedhomeip files.
+
+        $ cd {abs-path-to-connectedhomeip}
+        $ source ./scripts/bootstrap.sh
+        $ source ./scripts/activate.sh
+
+    Link connectedhomeip into ARMINO.
+
+        $ cd {abs-path-to-ARMINO}
+        $ ln -sfv {abs-path-to-connectedhomeip} components/matter/
+
+-   build project matter,and flash image file
+
+        $ cd {abs-path-to-ARMINO}
+        $ make bk7235 PROJECT=matter
+
+    the output bin file is {abs-path-to-ARMINO}/build/matter/bk7235/all-app.bin. you can use [WINDOWS BEKEN FLASH WRITE TOOL](http://dl.bekencorp.com:8192/tools/flash/BEKEN_WRITER_EN_V2.6.28_20220326.zip) to flash the demo application onto the device.
+
+
+## Commissioning over BLE using chip-tool
+
+-   Please build the standalone chip-tool as described [here](../../chip-tool)
+-   Commissioning the WiFi Lighting devices
+
+        $ ./out/debug/chip-tool pairing ble-wifi 12345 <ssid> <passphrase> 20202021 3840
+
+## Cluster Control
+
+After successful commissioning, use the OnOff cluster command to control the OnOff attribute. This allows you to toggle a parameter implemented by the device to be On or Off.
+
+    $ ./out/debug/chip-tool onoff on 12345 1
+
