Matter Telink Lighting Example Application

The Telink Lighting Example demonstrates how to remotely control a white dimmable light bulb. It uses buttons to test changing the lighting and device states and LEDs to show the state of these changes. You can use this example as a reference for creating your own application.

Telink B91 EVK

Build and flash

  1. Pull docker image from repository:

    $ docker pull connectedhomeip/chip-build-telink:latest
  2. Run docker container:

    $ docker run -it --rm -v ${CHIP_BASE}:/root/chip -v /dev/bus/usb:/dev/bus/usb --device-cgroup-rule "c 189:* rmw" connectedhomeip/chip-build-telink:latest

    here ${CHIP_BASE} is directory which contains CHIP repo files !!!Pay attention that OUTPUT_DIR should contains ABSOLUTE path to output dir

  3. Activate the build environment:

    $ source ./scripts/
  4. In the example dir run:

    $ west build
  5. Flash binary:

    $ west flash --erase



To get output from device, connect UART to following pins:

RXPB3 (pin 17 of J34 connector)
TXPB2 (pin 16 of J34 connector)


The following buttons are available on tlsr9518adk80d board:

Button 1Factory resetPerform factory reset to forget currently commissioned Thread network and back to uncommissioned state
Button 2Lighting controlManually triggers the lighting state
Button 3Thread startCommission thread with static credentials and enables the Thread on device
Button 4Open commission windowThe button is opening commissioning window to perform commissioning over BLE


Red LED indicates current state of Thread network. It ables to be in following states:

Blinks with short pulsesDevice is not commissioned to Thread, Thread is disabled
Blinls with frequent pulsesDevice is commissioned, Thread enabled. Device trying to JOIN thread network
Blinks with whde pulsesDevice commissioned and joined to thread network as CHILD

Blue LED shows current state of lightbulb

CHIP tool commands

  1. Build chip-tool cli

  2. Pair with device

    ${CHIP_TOOL_DIR}/chip-tool pairing ble-thread ${NODE_ID} hex:${DATASET} ${PIN_CODE} ${DISCRIMINATOR}


    ./chip-tool pairing ble-thread 1234 hex:0e080000000000010000000300000f35060004001fffe0020811111111222222220708fd61f77bd3df233e051000112233445566778899aabbccddeeff030e4f70656e54687265616444656d6f010212340410445f2b5ca6f2a93a55ce570a70efeecb0c0402a0fff8 20202021 3840
  3. Switch on the light:

    ${CHIP_TOOL_DIR}/chip-tool onoff on 1


    • onoff is name of cluster
    • on command to the cluster
    • 1 ID of endpoint
  4. Switch off the light:

    ${CHIP_TOOL_DIR}/chip-tool onoff off 1


    • onoff is name of cluster
    • off command to the cluster
    • 1 ID of endpoint
  5. Read the light state:

    ${CHIP_TOOL_DIR}/chip-tool onoff read on-off 1


    • onoff is name of cluster
    • read command to the cluster
    • on-off attribute to read
    • 1 ID of endpoint
  6. Change brightness of light:

    ${CHIP_TOOL_DIR}/chip-tool levelcontrol move-to-level 32 0 0 0 1


    • levelcontrol is name of cluster
    • move-to-level command to the cluster
    • 32 brightness value
    • 0 transition time
    • 0 option mask
    • 0 option override
    • 1 ID of endpoint
  7. Read brightness level:

    ./chip-tool levelcontrol read current-level 1


    • levelcontrol is name of cluster
    • read command to the cluster
    • current-level attribute to read
    • 1 ID of endpoint

OTA with Linux OTA Provider

OTA feature enabled by default only for ota-requestor-app example. To enable OTA feature for another Telink example:

  • set CONFIG_CHIP_OTA_REQUESTOR=y in corresponding “prj.conf” configuration file.

After build application with enabled OTA feature, use next binary files:

  • zephyr.bin - main binary to flash PCB (Use 2MB PCB).
  • zephyr-ota.bin - binary for OTA Provider

All binaries has the same SW version. To test OTA “zephyr-ota.bin” should have higher SW version than base SW. Set CONFIG_CHIP_DEVICE_SOFTWARE_VERSION=2 in corresponding “prj.conf” configuration file.

Usage of OTA:

  • Build the Linux OTA Provider

    ./scripts/examples/ examples/ota-provider-app/linux out/ota-provider-app chip_config_network_layer_ble=false
  • Run the Linux OTA Provider with OTA image.

    ./chip-ota-provider-app -f zephyr-ota.bin
  • Provision the Linux OTA Provider using chip-tool

    ./chip-tool pairing onnetwork ${OTA_PROVIDER_NODE_ID} 20202021


    • ${OTA_PROVIDER_NODE_ID} is the node id of Linux OTA Provider
  • Configure the ACL of the ota-provider-app to allow access

    ./chip-tool accesscontrol write acl '[{"fabricIndex": 1, "privilege": 5, "authMode": 2, "subjects": [112233], "targets": null}, {"fabricIndex": 1, "privilege": 3, "authMode": 2, "subjects": null, "targets": null}]' ${OTA_PROVIDER_NODE_ID} 0


    • ${OTA_PROVIDER_NODE_ID} is the node id of Linux OTA Provider
  • Use the chip-tool to announce the ota-provider-app to start the OTA process

    ./chip-tool otasoftwareupdaterequestor announce-ota-provider ${OTA_PROVIDER_NODE_ID} 0 0 0 ${DEVICE_NODE_ID} 0


    • ${OTA_PROVIDER_NODE_ID} is the node id of Linux OTA Provider
    • ${DEVICE_NODE_ID} is the node id of paired device

Once the transfer is complete, OTA requestor sends ApplyUpdateRequest command to OTA provider for applying the image. Device will restart on successful application of OTA image.
