Matter Bouffalo Lab Contact Sensor Example

This example functions as a contact sensor uses a test Vendor ID (VID) and a Product ID (PID) of 0x8005.

Supported board:

• bl704ldk

Build CHIP Contact Sensor example

./scripts/build/build_examples.py --target bouffalolab-bl704ldk-contact-sensor-thread-mtd-littlefs build

Test with chip-tool

Commissioning over BLE

• Reset the board or factory reset the board

• Enter build out folder of chip-tool and running the following command to do BLE commission

  • Thread

    ```shell
    ./out/linux-x64-chip-tool/chip-tool pairing ble-thread <deivce_node_id> hex:<thread_operational_dataset> 20202021 3840
    ```
    

    <deivce_node_id>, which is node ID assigned to device within chip-tool <thread_operational_dataset>, Thread network credential which running sudo ot-ctl dataset active -x command on border router to get.

Subscribe booleanstate of contact sensor

• Start chip-tool with interactive mode

  ./chip-tool interactive start
  

• Subscribe booleanstate under chip-tool interactive mode

  booleanstate subscribe state-value <min-interva> <max-interval> <deivce_node_id> 1
  

  • <min-interva>, min interval to report to boolean state of contact sensor
  • <max-interva>, max interval to report to boolean state of contact sensor
  • <deivce_node_id>, node id of contact sensor

• Press down INT button, boolean state True will report to chip-tool

  GPIO 20 connects to INT button.

• After press down INT button over min-interva> seconds, and release INT button, boolean state False will report to chip-tool
