#CHIP BL602 Lighting Example

Build

• Install some additional tools(likely already present for CHIP developers):

  #Linux $ sudo apt-get install git libwebkitgtk-1.0-0 ninja-build

  #Mac OS X $ brew install ninja

• Build the example application:

  connectedhomeip$ ./scripts/build/build_examples.py --target bl602-lighting build

Generated files

     connectedhomeip/out/lighting_app_bl602/chip-bl602-lighting-example.bin

• To delete generated executable, libraries and object files use:

    $ cd ~/connectedhomeip/
    $ rm -rf out/
  

Flash

• Download FLASH_TOOL.

Setting up Python Controller

Once BL602 is up and running, we need to set up a device controller to perform commissioning and cluster control.

• Set up python controller.

     $ cd {path-to-connectedhomeip}
     $ ./scripts/build_python.sh -m platform
  

• Execute the controller.

     $ source ./out/python_env/bin/activate
     $ chip-device-ctrl
  

Commissioning over BLE

• Establish the secure session over BLE. BLE is the default mode in the application and is configurable through menuconfig.

   - chip-device-ctrl > ble-scan
   - chip-device-ctrl > set-pairing-wifi-credential TESTSSID P455W4RD
   - chip-device-ctrl > connect -ble 3904 20202021 135246
  
   Parameters:
   1. Discriminator: 3904
   2. Setup-pin-code: 20202021
   3. Node ID: Optional.
      If not passed in this command, then it is auto-generated by the controller and displayed in the output of connect.
      The same value should be used in the next commands.
      We have chosen a random node ID which is 135246.
   4. TESTSSID : Wi-Fi SSID
   5. P455W4RD : Wi-Fi Password
  

Cluster control

• After successful commissioning, use the OnOff cluster commands to control the OnOff attribute. This allows you to toggle a parameter implemented by the device to be On or Off.

  chip-device-ctrl > zcl OnOff On 135246 1 1 chip-device-ctrl > zcl OnOff Off 135246 1 1

• Use the LevelControl cluster commands to control the CurrentLevel attribute. This allows you to control the brightness of the led.

  chip-device-ctrl > zcl LevelControl MoveToLevel 135246 1 1 level=10 transitionTime=0 optionMask=0 optionOverride=0

• Use the ColorControl cluster commands to control the CurrentHue and CurrentSaturation attribute.

  chip-device-ctrl > zcl ColorControl MoveToHue 135246 1 1 hue=100 direction=0 transitionTime=0 optionsMask=0 optionsOverride=0 chip-device-ctrl > zcl ColorControl MoveToSaturation 135245 1 1 saturation=200 transitionTime=0 optionsMask=0 optionsOverride=0
