Test with chip-tool

Commissioning

Reset or factory reset the board first, then enter the chip-tool output directory and run the commissioning command for the selected transport.

• Wi-Fi

  ./chip-tool pairing ble-wifi <device_node_id> <wifi_ssid> <wifi_passwd> 20202021 3840
  

• Thread

  ./chip-tool pairing ble-thread <device_node_id> hex:<thread_operational_dataset> 20202021 3840
  

• Ethernet

  ./chip-tool pairing onnetwork <device_node_id> 20202021
  

<device_node_id> - node ID assigned to the device with chip-tool;
> <wifi_ssid> - Wi-Fi network SSID;
> <wifi_passwd> - Wi-Fi network password;
> <thread_operational_dataset> - Thread network credentials, which can be obtained by running sudo ot-ctl dataset active -x on the border router.

Cluster Control

After successful commissioning, use the cluster commands below to control the board.

• OnOff cluster

  The following command toggles the LED on the board:

  ./chip-tool onoff toggle <device_node_id> 1
  

• LevelControl cluster

  The following command moves the level to 128:

  ./chip-tool levelcontrol move-to-level 128 10 0 0 <device_node_id> 1
  

• ColorControl cluster

  The following command changes hue and saturation to 240 and 100:

  ./chip-tool colorcontrol move-to-hue-and-saturation 240 100 0 0 0 <device_node_id> 1
  

• Identify cluster

  The following command identifies the board for 10 seconds:

  ./chip-tool identify identify 10 <device_node_id> 1
