Test with chip-tool

Use standalone chip-tool app(linux) to communicate with the device.

In order to send commands to a device, it must be commissioned with the client. chip-tool currently only supports commissioning and remembering one device at a time. The configuration state is stored in /tmp/chip_tool_config.ini; deleting this and other .ini files in /tmp can sometimes resolve issues due to stale configuration.

Bypass Rendezvous

  • Enter the ATCMD ATS$
  • Connect to AP using ATW0, ATW1, ATWC commands
  • Run CHIP-TOOL IP commissioning command ./chip-tool pairing bypass XXX.XXX.XXX.XXX 5540 (Ameba IP)

IP Commissioning

  • Enter the ATCMD ATS$
  • Connect to AP using ATW0, ATW1, ATWC commands
  • Run CHIP-TOOL IP commissioning command ./chip-tool pairing onnetwork 0 20202021 3840 XXX.XXX.XXX.XXX 5540 (Ameba IP)

BLE Commissioning

  • Enter the ATCMD ATS$
  • Run CHIP-TOOL IP commissioning command ./chip-tool pairing ble-wifi SSID PASSWORD 0 20202021 3840

Command for onoff cluster

Use PB_5 as output, connect a LED to this pin and GND.

  • Run CHIP-TOOL on-off cluster command ./chip-tool onoff on 1

  • Run CHIP-TOOL on-off cluster command ./chip-tool onoff off 1

Command for doorlock cluster

Get doork lock cluster command on Ameba

  • Run CHIP-TOOL on-off cluster command ./chip-tool doorlock lock-door 1 1

  • Run CHIP-TOOL on-off cluster command ./chip-tool doorlock unlock-door 1 1

Test with Python Controller

To build the Python Controller (linux), run the following command.

./scripts/build_python.sh --clusters_for_ip_commissioning true --chip_mdns platform

To launch Python Controller, activate the python environment first.

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

IP Commissioning

  • Enter the ATCMD ATS$
  • Connect to AP using ATW0, ATW1, ATWC commands
  • Run python controller IP commissioning command chip-device-ctrl > connect -ip <IP> 20202021 135246
  • Resolve DNS-SD name and update address of the node in the device controller. Get fabric ID using get-fabricid and use the decimal value of compressed fabric id. chip-device-ctrl > get-fabricid
  • Resolve mDNS chip-device-ctrl > resolve <Compressed Fabric ID> 135246
  • On-Off cluster command chip-device-ctrl >zcl OnOff On 135246 1 1
  • On-Off cluster command chip-device-ctrl >zcl OnOff Off 135246 1 1

BLE Commissioning

  • Enter the ATCMD ATS$

  • Run python controller BLE commissioning command chip-device-ctrl > connect -ble 3840 20202021 135246

  • Provide network credentials chip-device-ctrl > zcl NetworkCommissioning AddWiFiNetwork 135246 0 0 ssid=str:TESTSSID credentials=str:TESTPASSWD breadcrumb=0 timeoutMs=1000

  • Connect to AP chip-device-ctrl > zcl NetworkCommissioning EnableNetwork 135246 0 0 networkID=str:TESTSSID breadcrumb=0 timeoutMs=1000

  • Close the BLE connection chip-device-ctrl > close-ble

  • Resolve DNS-SD name and update address of the node in the device controller. Get fabric ID using get-fabricid and use the decimal value of compressed fabric id. chip-device-ctrl > get-fabricid

  • Resolve mDNS chip-device-ctrl >resolve <Compressed Fabric ID> 135246

  • On-Off cluster command chip-device-ctrl >zcl OnOff On 135246 1 1

  • On-Off cluster command chip-device-ctrl >zcl OnOff Off 135246 1 1
