Matter Telink Temperature Measurement Example Application

The Telink Temperature Measurement Example demonstrates getting simulated data from temperature sensor. In further releases the real sensor handling will be implemented along. It uses buttons to test changing the device states and LEDs to show the state of these changes. You can use this example as a reference for creating your own application.

Build and flash

1. Run the Docker container:

   $ docker run -it --rm -v $PWD:/host -w /host ghcr.io/project-chip/chip-build-telink:$(wget -q -O - https://raw.githubusercontent.com/project-chip/connectedhomeip/master/.github/workflows/examples-telink.yaml 2> /dev/null | grep chip-build-telink | awk -F: '{print $NF}')
   

   Compatible docker image version can be found in next file:

   $ .github/workflows/examples-telink.yaml
   

2. Activate the build environment:

   $ source ./scripts/activate.sh -p all,telink
   

3. In the example dir run (replace <build_target> with your board name, for example, tlsr9518adk80d, tlsr9528a or tlsr9258a):

   $ west build -b <build_target>
   

   Also use key -DFLASH_SIZE, if your board has memory size different from 2 MB, for example, -DFLASH_SIZE=1m or -DFLASH_SIZE=4m:

   $ west build -b tlsr9518adk80d -- -DFLASH_SIZE=4m
   

4. Flash binary:

   $ west flash --erase
   

Usage

UART

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

Buttons

The following buttons are available on tlsr9518adk80d board:

LEDs

Indicate current state of Thread network

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

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}
   

   Example:

   ./chip-tool pairing ble-thread 1234 hex:0e080000000000010000000300000f35060004001fffe0020811111111222222220708fd61f77bd3df233e051000112233445566778899aabbccddeeff030e4f70656e54687265616444656d6f010212340410445f2b5ca6f2a93a55ce570a70efeecb0c0402a0fff8 20202021 3840
   

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 at least 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/gn_build_example.sh 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
  

  here:

  • ${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
  

  here:

  • ${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-otaprovider ${OTA_PROVIDER_NODE_ID} 0 0 0 ${DEVICE_NODE_ID} 0
  

  here:

  • ${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.
