The CYW30739 light switch example provides a baseline demonstration of a on-off light switch device, built using Matter and the Infineon Modustoolbox SDK. It can be controlled by a Matter controller over Openthread network.
The CYW30739 device can be commissioned over Bluetooth Low Energy where the device and the Matter controller will exchange security information with the Rendez-vous procedure. Target Thread Network information including the active dataset and CASE credentials are then provided.
Build the example application:
$ cd ~/connectedhomeip $ git submodule update --init $ ./scripts/examples/gn_build_example.sh examples/light-switch-app/infineon/cyw30739 out/light-switch-app
To delete generated executable, libraries and object files use:
$ cd ~/connectedhomeip $ rm -rf ./out/
OR use GN/Ninja directly
$ cd ~/connectedhomeip/examples/light-switch-app/infineon/cyw30739 $ git submodule update --init $ source third_party/connectedhomeip/scripts/activate.sh $ gn gen out/debug $ ninja -C out/debug
To delete generated executable, libraries and object files use:
$ cd ~/connectedhomeip/examples/light-switch-app/infineon/cyw30739 $ rm -rf out/
Infineon CYW30739 examples use test certifications, keys, and CD by default. For a production build, manufacturers can provision certifications, keys, and CD by the following arguments:
matter_dac
, matter_dac_key
, matter_pai
, matter_cd
$ ./scripts/examples/gn_build_example.sh examples/light-switch-app/infineon/cyw30739 out/light-switch-app \ 'matter_dac="/path/to/dac.der"' \ 'matter_dac_key="/path/to/dac_key.der"' \ 'matter_pai="/path/to/pai.der"' \ 'matter_cd="/path/to/cd.der"'
Put the CYW30739 in to the recovery mode before running the flash script.

It is assumed here that you already have an OpenThread border router configured and running. If not see the following guide Openthread_border_router for more information on how to setup a border router on a raspberryPi.
For this example to work, it is necessary to have a second CYW30739 device running the lighting app example commissioned on the same OpenThread network
If the CYW30739 device is running the light switch example, then
Push USER Button - Sends a Toggle command to bound light app.
LED1 - Indicates the current button state.
OnOff Cluster - As following commands are app shell commands.
- 'switch local on' : Lights On LED1 of light-switch device - 'switch local off' : Lights Off LED1 of light-switch device - 'switch local toggle' : Makes Toggle LED1 of light-switch device - 'switch onoff on' : Sends unicast On command to bound device - 'switch onoff off' : Sends unicast Off command to bound device - 'switch onoff toggle' : Sends unicast Toggle command to bound device - 'switch groups onoff on' : Sends On group command to bound group - 'switch groups onoff off' : Sends On group command to bound group - 'switch groups onoff toggle' : Sends On group command to bound group
Here is an example with the CHIPTool for unicast commands only:
chip-tool pairing ble-thread 1 hex:<operationalDataset> 20202021 3840 chip-tool accesscontrol write acl '[{"fabricIndex": 1, "privilege": 5, "authMode": 2, "subjects": [<chip-tool-node-id>], "targets": null}, {"fabricIndex": 1, "privilege": 3, "authMode": 2, "subjects": [<light-switch-node-id>], "targets": [{"cluster": 6, "endpoint": 1, "deviceType": null}]}]' <lighting-node-id> 0 chip-tool binding write binding '[{"fabricIndex": 1, "node": <lighting-node-id>, "endpoint": 1, "cluster": 6}]' <light-switch-node-id> 1
Example: After pairing successfully [lighting-node-id : 1, light-switch-node-id : 2]
chip-tool accesscontrol write acl '[{"fabricIndex": 1, "privilege": 5, "authMode": 2, "subjects": [112233], "targets": null}, {"fabricIndex": 1, "privilege": 3, "authMode": 2, "subjects": [2], "targets": [{"cluster": 6, "endpoint": 1, "deviceType": null}]}]' 1 0 chip-tool binding write binding '[{"fabricIndex": 1, "node": 1, "endpoint": 1, "cluster": 6}]' 2 1
Here is an example with the CHIPTool for groups commands only:
Pairing the device
chip-tool pairing ble-thread 1 hex:<operationalDataset> 20202021 3840
You can use a series of commands after pairing successfully. Here is a lighting device (node 1) and a light-switch device (node 2) for connection demonstration.
chip-tool groupkeymanagement key-set-write '{"groupKeySetID": 417, "groupKeySecurityPolicy": 0, "epochKey0":"a0a1a2a3a4a5a6a7a8a9aaabacadaeaf", "epochStartTime0": 1110000,"epochKey1":"b0b1b2b3b4b5b6b7b8b9babbbcbdbebf", "epochStartTime1":1110001,"epochKey2":"c0c1c2c3c4c5c6c7c8c9cacbcccdcecf", "epochStartTime2": 1110002 }' 1 0 chip-tool groupkeymanagement write group-key-map '[{"groupId": 257, "groupKeySetID": 417, "fabricIndex": 1}]' 1 0 chip-tool groups add-group 257 demo 1 1 chip-tool accesscontrol write acl '[{"fabricIndex": 1, "privilege": 5, "authMode": 2, "subjects": null, "targets": null}, {"fabricIndex": 1, "privilege": 3, "authMode": 3, "subjects": [257], "targets": null}]' 1 0 chip-tool groupkeymanagement key-set-write '{"groupKeySetID": 417, "groupKeySecurityPolicy": 0, "epochKey0":"a0a1a2a3a4a5a6a7a8a9aaabacadaeaf", "epochStartTime0": 1110000,"epochKey1":"b0b1b2b3b4b5b6b7b8b9babbbcbdbebf", "epochStartTime1":1110001,"epochKey2":"c0c1c2c3c4c5c6c7c8c9cacbcccdcecf", "epochStartTime2": 1110002 }' 2 0 chip-tool groupkeymanagement write group-key-map '[{"groupId": 257, "groupKeySetID": 417, "fabricIndex": 1}]' 2 0 chip-tool groups add-group 257 demo 2 1 chip-tool binding write binding '[{"fabricIndex": 1, "group": 257}]' 2 1
Or you can use TestGroupDemoConfig after pairing successfully
chip-tool tests TestGroupDemoConfig --nodeId <light-switch-node-id> chip-tool tests TestGroupDemoConfig --nodeId <lighting-node-id> chip-tool binding write binding '[{"fabricIndex": 1, "group": 257}]' <light-switch-node-id> 1
Example: After pairing successfully [lighting-node-id : 1, light-switch-node-id : 2]
chip-tool tests TestGroupDemoConfig --nodeId 2 chip-tool tests TestGroupDemoConfig --nodeId 1 chip-tool binding write binding '[{"fabricIndex": 1, "group": 257}]' 2 1
To run the example with unicast and groups commands, run the group configuration commands and replace the last one with binding this command
chip-tool binding write binding '[{"fabricIndex": 1, "group": 257},{"fabricIndex": 1, "node": <lighting-node-id>, "endpoint": 1, "cluster":6} ]' <light-switch-node-id> 1
To acquire the chip-tool node id, read the acl table right after commissioning
chip-tool accesscontrol read acl <nodeid> 0
