# Matter Telink All Clusters Minimal Example Application

The Telink All Clusters Minimal Example Application implements various ZCL
clusters populated on three endpoints. You can use this example as a reference
for creating your own application.

## Build and flash

1. Pull docker image from repository:

    ```bash
    $ docker pull connectedhomeip/chip-build-telink:latest
    ```

1. Run docker container:

    ```bash
    $ 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**

1. Activate the build environment:

    ```bash
    $ source ./scripts/activate.sh
    ```

1. In the example dir run:

    ```bash
    $ west build
    ```

1. Flash binary:

    ```
    $ west flash --erase
    ```

## Usage

### UART

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

| Name | Pin                           |
| :--: | :---------------------------- |
|  RX  | PB3 (pin 17 of J34 connector) |
|  TX  | PB2 (pin 16 of J34 connector) |
| GND  | GND                           |

### Buttons

The following buttons are available on **tlsr9518adk80d** board:

| Name     | Function               | Description                                                                                            |

| Button 2 | Not used               | Not used                                                                                               |
| Button 2 | Not used               | Not used                                                                                               |
| Button 4 | Open commission window | The button is opening commissioning window to perform commissioning over BLE                           |

### LEDs

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

| State                       | Description                                                                  |
| :-------------------------- | :--------------------------------------------------------------------------- |
| Blinks with short pulses    | Device is not commissioned to Thread, Thread is disabled                     |
| Blinls with frequent pulses | Device is commissioned, Thread enabled. Device trying to JOIN thread network |
| Blinks with whde pulses     | Device commissioned and joined to thread network as CHILD                    |

### CHIP tool commands

1. Build
   [chip-tool cli](https://github.com/project-chip/connectedhomeip/blob/master/examples/chip-tool/README.md)

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 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](https://github.com/project-chip/connectedhomeip/blob/master/examples/ota-provider-app/linux)

    ```
    ./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-ota-provider ${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.
