This document provides full guidance of Telink matter solution which
includes such to/uploads/zip/20230607200713DN6A9/pics as environment setup, Matter device firmware building
and flashing, Border Router setup including RCP building and flashing,
building and usage of chip-tool etc.
To avoid routine with Zephyr environment setup in section 3.2.1 and 3.2.3,
user can just pull and run existing docker image that contains ready to use
environment.
Run the Docker container (this will take a while to complete the first time):
For Matter v1.0-branch branch use the following line:
docker run -it --rm -v $PWD:/host -w /host connectedhomeip/chip-build-telink:$(wget -q -O - https://raw.githubusercontent.com/project-chip/connectedhomeip/v1.0-branch/.github/workflows/examples-telink.yaml 2> /dev/null | grep chip-build-telink | awk -F: '{print $NF}')Docker image 'connectedhomeip/chip-build-telink:0.6.06'
For Matter master branch use the following line:
docker run -it --rm -v $PWD:/host -w /host connectedhomeip/chip-build-telink:$(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}')Docker image 'connectedhomeip/chip-build-telink:0.6.47'
Compatible docker image version can be found in next file:
.github/workflows/examples-telink.yamlSetup dependencies:
In the new terminal go through Step 1 in
3.2.2 Matter project setup to setup dependencies.
Matter project:
In the Docker container go through Step 2-4 in
3.2.2 Matter project setup to clone Matter
repository into a clean folder, update submodules for Telink platform and run bootstrap.
Then, follow instruction in Chapter 4. Matter Firmware to build firmware.
Please execute APT update and upgrade before the following steps.
sudo apt update
sudo apt upgradeInstall dependencies:

CONFIG_OPENTHREAD_MTD=yFTD (Full Thread Device) configuration example:
# OpenThread configs
CONFIG_OPENTHREAD_MTD=nNote: Option not set has the same effect
Low power configuration options:
Optional tuning:
The configuration option CONFIG_TELINK_BUTTON_MANAGER_IRQ_MODE requires reconnection of the buttons by the following schematic and requires the external buttons usage in case of using the TLSR9218ADK80d EVK:
| Name | Pin |
|---|---|
| BUTTON_1 | PC2 (pin 16 of J20) |
| BUTTON_2 | PC0 (pin 18 of J20) |
| BUTTON_3 | PC3 (pin 20 of J20) |
| BUTTON_4 | PC1 (pin 22 of J20) |
The second side buttons pins need to be connected together and connected to the GND. In case of using TLSR9218ADK80d EVK any GND pin on the back side of the board can be choosed.
This kind of connection pulls up the GPIO internally and the button event comes by FALLING EDGE on GPIO.
The current consumption with this configuration can be achieved as low as:
Setting max RF power configuration example:
# Custom RF power values
CONFIG_B91_BLE_CTRL_RF_POWER_P9P11DBM=y
CONFIG_OPENTHREAD_DEFAULT_TX_POWER=9Note: CONFIG_OPENTHREAD_DEFAULT_TX_POWER is a value in dBm, valid range: -30 .. 9, by default it's zero.
Note: CONFIG_CHIP_OPENTHREAD_TX_POWER may used in older version.

To indicate the Tilt state in the same way connect external LED to board pin PE0.
A Bridge serves to allow the use of non-Matter IoT devices (e.g. devices on a Zigbee or Z-Wave net
work, or any other non-Matter connectivity technology) in a Matter Fabric, with the goal to enable
the consumer to keep using these non-Matter devices together with their Matter devices.
The Telink Bridge Example demonstrates a simple lighting bridge and the use of
dynamic endpoints.
The Bridge device performs the translation between Matter and other protocols so that the Matter nodes
can communicate with the Bridged Devices.
A Bridge may also contain native Matter functionality, for example,
it may itself be a Temperature sensor having both Thread and Zigbee connection.
As said in Matter Specification, this is illustrated in the figure below: the non-Matter devices are exposed as Bridged Devices to
Nodes on the Fabric. The Matter Nodes can communicate with both the (native) Matter devices as
well as the Bridged Devices (by virtue of the Bridge which performs the translation between Matter
and the other protocol).
Open Thread border router is composed device which contains two main parts:
Two devices can be used for creating RCP device.
In this case the RCP is an additional TLSR9518ADK80D board (B91 Generic Starter Kit).

Due to there's only one full featured UART port availabe on RPi 3, some additional actions are needed:
Disable console and logging over UART
Login into RPi via ssh and activate configuration tool:
sudo raspi-configSellect "3 Interface options"
Sellect "I6 Serial Port"
For "Would you like a login shell to be accessible over serial?" answer "No"
For "Would you like the serial port hardware to be enabled?" answer "Yes"
Close the tool by sellecting "Finnish"
Switch BLE chip to use miniUART instead of full featured UART
put:
dtoverlay=pi3-miniuart-btat the end of /boot/config.txt file
reboot the board.
sudo rebootConfigure GPIOs to act as HW flow control (RTS and CTS)
There are variety of tools to do that. The method tested and working is described below:
Login into Rpi console and fetch the tool:
git clone https://github.com/mholling/rpirtscts.gitCompile the tool:
cd rpirtscts/
makeUse the tool:
sudo ./rpirtscts onThe output should show which pins are used for HW flow control:
assuming 40-pin GPIO header
Enabling CTS0 and RTS0 on GPIOs 16 and 17Shut down the board
sudo haltWait until "activity" (green) light stops flashing and power off the RPi board.
Connect Telink RCP to 40-pin headder of RPi

| GND - (pin 9) | GND - (pin 6) ot (pin 9) |
Start the board and login into the console.
alter the file: /etc/default/otbr-agent
- OTBR_AGENT_OPTS="-I wpan0 -B eth0 spinel+hdlc+uart:///dev/ttyACM0 trel://eth0"
+ OTBR_AGENT_OPTS="-I wpan0 -B eth0 spinel+hdlc+uart:///dev/ttyAMA0?uart-flow-control trel://eth0"Reboot the board and try to from Thread network.
(not recommended due to stability issues)
With additional USB->UART converter it is possible to bould OT Border router with RPi 3.
Prepare Raspberry PI 3 OT boarder router as above but DO NOT form thread network yet!
Connect Telink board to USB dongle:
| RCP Telink B91 J20 header | USB -> UART Dongle |
|---|---|
| TX - PC6 (pin 11) | RX |
| RX - PC7 (pin 12) | TX |
| RTS - PC5 (pin 14) | CTS |
| CTS - PC4 (pin 13) | RTS |
| GND (e.g., pin 23 of J50 or pin 3 of J56) | GND |
Login into RPI via ssh and connect USB dongle.
Check device file assigned to your dongle:
$ dmesgusb 1-1.3: new full-speed USB device number 7 using dwc_otg
[ 4112.930175] usb 1-1.3: New USB device found, idVendor=0403, idProduct=6001, bcdDevice= 6.00

in our case it's ttyUSB0
5. Modify */etc/default/otbr-agent* file by replacing default string with
following difference:
- OTBR_AGENT_OPTS="-I wpan0 -B eth0 spinel+hdlc+uart:///dev/ttyACM0 trel://eth0"
+ OTBR_AGENT_OPTS="-I wpan0 -B eth0 spinel+hdlc+uart:///dev/ttyUSB0?uart-flow-control trel://eth0"
replacing "ttyUSB0" with device file you obtained in step 4.
6. Reboot the board
```bash
$ sudo rebootWait until reboot. Now it should be possible to use border router.

check OTBR instalation and Thread NW forming. Check /var/log/messages for errors.
Use Matter Demo Device address obtained in 2. and ping it from host PC (machiner rynning chip-tool).
If ping from host PC works, chip-tool onnetwork pairing shall be working too. Remove cached data:
sudo rm -rf /tmp/chip_*and check again:

Binding links clusters and endpoints on both devices, which enables them to
communicate with each other.
To perform binding, you need a controller that can write the binding table
to the light switch device and write proper ACL to the endpoint light bulb
on the Lighting Example application.
For example, you can use the CHIP Tool as the controller.
The ACL should contain information about all clusters that can be called by
the light switch application.
See the section about interacting with ZCL clusters in the CHIP Tool's user
guide for more information about ACLs.
You can perform the binding process to a single remote endpoint (unicast
binding) or to a group of remote endpoints (group multicast).
Note: To use a light switch without brightness dimmer, apply only the
first binding command with cluster no. 6.
In this scenario, commands are provided for a light switch device with the
nodeId = <light-switch-node-id> and a light bulb device with
nodeId = <lighting-node-id>, both commissioned to the same Matter network.
To perform the unicast binding process, complete the following steps:
Add an ACL to the development kit that is programmed with the Lighting
Application Example by running the following command:
./chip-tool accesscontrol write acl '[{"fabricIndex": 1, "privilege": 5, "authMode": 2, "subjects": [112233], "targets": null}, {"fabricIndex": 1, "privilege": 3, "authMode": 2, "subjects": [<light-switch-node-id>], "targets": [{"cluster": 6, "endpoint": 1, "deviceType": null}, {"cluster": 8, "endpoint": 1, "deviceType": null}]}]' <lighting-node-id> 0In this command:
[...] is JSON format message for attr-value so <light-switch-node-id> must be a real number when the command is<lighting-node-id> can be a shell variable as ${NODE_ID} used{"fabricIndex": 1, "privilege": 5, "authMode": 2, "subjects": [112233], "targets": null}{"fabricIndex": 1, "privilege": 5, "authMode": 2, "subjects": [<light-switch-node-id>], "targets": [{"cluster": 6, "endpoint": 1, "deviceType": null}, {"cluster": 8, "endpoint": 1, "deviceType": null}]}This command adds permissions on the lighting application device that
allows it to receive commands from the light switch device.
Add a binding table to the Light Switch binding cluster:
./chip-tool binding write binding '[{"fabricIndex": 1, "node": <lighting-node-id>, "endpoint": 1, "cluster": 6}]' <light-switch-node-id> 1In this command:
[...] is JSON format message for attr-value so <lighting-node-id> must be real numbers when the command is executed.<light-switch-node-id> can be a shell variable such as ${SWITCH_NODE_ID} used by chip-tool to do commissioning with Lighting Switch App.{"fabricIndex": 1, "node": <lighting-node-id>, "endpoint": 1, "cluster": 6} is a binding for the On/Off cluster.The group multicast binding lets you control more than one lighting device
at a time using a single light switch.
The group multicast binding targets all development kits that are
programmed with the Lighting Application Example and added to the same
multicast group.
After the binding is established, the light switch device can send multicast requests, and all the devices in the bound groups can run the
received command.
In this scenario, commands are provided for a light switch device with the
nodeId = <light-switch-node-id> and light bulb devices with
nodeId = <lighting-node-id>, all commissioned to the same Matter network.
To perform the multicast binding process, complete the following steps:
Add the light switch device to the multicast group by running the
following command:
./chip-tool tests TestGroupDemoConfig --nodeId <light-switch-node-id><light-switch-node-id> can be a shell variable such as ${SWITCH_NODE_ID} used by chip-tool to do commissioning with Lighting Switch App.Add all light bulbs to the same multicast group by applying command
below for each of the light bulbs, using the appropriate
<lighting-node-id> (the user-defined ID of the node being commissioned
except <light-switch-node-id> due to use this <light-switch-node-id>
for light-switch) for each of them:
./chip-tool tests TestGroupDemoConfig --nodeId <lighting-node-id><lighting-node-id> can be shell variables as ${NODE_ID}s usedAdd Binding commands for group multicast:
./chip-tool binding write binding '[{"fabricIndex": 1, "group": 257}]' <light-switch-node-id> 1<light-switch-node-id> can be a shell variable such asTo test the communication between the light switch device and the bound
devices, use light switch buttons.
OTA feature enabled by default only for ota-requestor-app example.
To enable OTA feature for another Telink example:
CONFIG_CHIP_OTA_REQUESTOR=y in corresponding "prj.conf" configuration file.After build application with enabled OTA feature, use next binary files:
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.
For Matter v1.0-branch branch used by default swap mode that run with the scratch partition (BOOT_SWAP_USING_SCRATCH).
For Matter master branch used by default swap mode that can run without a scratch partition (BOOT_SWAP_USING_MOVE).
To change swap mode back to BOOT_SWAP_USING_SCRATCH for master branch:
Remove -DCONFIG_BOOT_SWAP_USING_MOVE=y cofing from build_mcuboot in CMakeLists.txt file.
Add scratch_partition into tlsr9518adk80d.overlay.
See Flash Layout and the following table for more details.
The following are the possible scratch partition layouts. Can be replaced with the one from the overlay file. The bigger scratch partition is the faster the swapping is done. Be aware that the bigger scratch partition is the smaller partitions for the code (slot0 and slot1) are.

chip-device-ctrl > zcl OnOff Toggle ${NODE_ID} 1 0Factory data is a set of device parameters written to the non-volatile memory
during the manufacturing process. This guide describes the process of creating
and programming factory data using Matter and the Telink platform from
Telink Semiconductor.
The factory data parameter set includes different types of information, for
example about device certificates, cryptographic keys, device identifiers, and
hardware. All those parameters are vendor-specific and must be inserted into a
device's persistent storage during the manufacturing process. The factory data
parameters are read at the boot time of a device. Then, they can be used in the
Matter stack and user application (for example during commissioning).
All of the factory data parameters are protected against modifications by the
software, and the firmware data parameter set must be kept unchanged during the
lifetime of the device. When implementing your firmware, you must make sure that
the factory data parameters are not re-written or overwritten during the Device
Firmware Update or factory resets, except in some vendor-defined cases.
For the Telink platform, the factory data is stored by default in a
separate partition of the internal flash memory.
You can implement the factory data set described in the
factory data component table in various ways,
as long as the final HEX/BIN file contains all mandatory components defined in the
table. In this guide, the generating factory data
and the
building an example with factory data
sections describe one of the implementations of the factory data set created by
the Telink platform's maintainers. At the end of the process, you get a HEX
file that contains the factory data partition in the CBOR format.
The factory data accessor is a component that reads and decodes factory data
parameters from the device's persistent storage and creates an interface to
provide all of them to the Matter stack and to the user application.
The default implementation of the factory data accessor assumes that the factory
data stored in the device's flash memory is provided in the CBOR format.
However, it is possible to generate the factory data set without using the
Telink scripts and implement another parser and a factory data accessor. This
is possible if the newly provided implementation is consistent with the
Factory Data Provider.
For more information about preparing a factory data accessor, see the section
about
using own factory data implementation.
Note: Encryption and security of the factory data partition is not provided
yet for this feature.

flash memory of the Matter device.
In the Telink example, the factory data set is represented in the CBOR
format and is stored in a HEX/BIN file. The file is then programmed to a device.
All parameters of the factory data set are either mandatory or optional:
user data parameter consists of all data that is needed by aIn the factory data set, the following formats are used:
0255(inclusive), without any encoding.YYYY-MM-DD or YYYYMMDD format.By default, the factory data support is disabled in all Telink examples and
the Telink device uses predefined parameters from the Matter core, which
you should not change. To start using factory data stored in the flash memory
and the Factory Data Provider from the Telink platform, build an
example with the following option:
west build -- -DCONFIG_CHIP_FACTORY_DATA=yThis section describes how to generate factory data partition image.
Please make sure you have had the following tools before using the generator
tool.

within which all partitions are declared.
To prepare an example that supports factory data, add a partition called factory-data
to the tlsr9518adk80d.dts/tlsr9518adk80d.overlay file. The partition size should be a multiple of one
flash page (for B91 SoCs, a single page size equals 4 kB).
See Flash Layout for an example of a factory data partition in the
tlsr9518adk80d.dts/tlsr9518adk80d.overlay file.
factory-data partition size has been set to one flash page (4 kB).

└── summary.jsonNote: By default, overwriting the existing output directory is disabled. This means
that you cannot create a new directory with the same name in the exact
location as an existing file. To allow overwriting, add the--overwrite
option to the argument list of the Python script.
You can manually generate the factory data set using the instructions described
in the Generating factory data section. Another way
is to use the Telink platform build system that creates factory data
content automatically using Kconfig options and includes the content in the
final firmware binary.
To enable generating the factory data set automatically, go to the example's
directory and build the example with the following option:
west build -- -DCONFIG_CHIP_FACTORY_DATA=y -DCONFIG_CHIP_FACTORY_DATA_BUILD=yAlternatively, you can also add CONFIG_CHIP_FACTORY_DATA_BUILD=y Kconfig
setting to the example's prj.conf file.
Each factory data parameter has a default value. These are described in the
Kconfig file. Setting a new value
for the factory data parameter can be done either by providing it as a build
argument list or by using interactive Kconfig interfaces.
This way for providing factory data can be used with third-party build script,
as it uses only one command. All parameters can be edited manually by providing
them as an additional option for the west command:
west build -- -DCONFIG_CHIP_FACTORY_DATA=y --DCONFIG_CHIP_FACTORY_DATA_BUILD=y --DCONFIG_CHIP_DEVICE_DISCRIMINATOR=0xF11Alternatively, you can add the relevant Kconfig option lines to the example's
prj.conf file.
The HEX/BIN file containing factory data can be programmed into the device's flash
memory using BDT Tool and the Telink burning key.
Another way to program the factory data to a device is to use the Telink
platform build system described in
Building an example with factory data,
and build an example with the additional option
-DCONFIG_CHIP_FACTORY_DATA_MERGE_WITH_FIRMWARE=y:
$ west build -- \

You can also build an example with auto-generation of new CD, DAC and PAI
certificates. The newly generated certificates will be added to factory data set
automatically. To generate new certificates disable using default certificates
by building an example with the additional option
-DCHIP_FACTORY_DATA_USE_DEFAULT_CERTS=n:
$ west build -- \
-DCONFIG_CHIP_FACTORY_DATA=y \
-DCONFIG_CHIP_FACTORY_DATA_BUILD=y \
-DCONFIG_CHIP_FACTORY_DATA_MERGE_WITH_FIRMWARE=y \
-DCONFIG_CHIP_FACTORY_DATA_USE_DEFAULT_CERTS=nNote: To generate new certificates using the Telink platform build
system, you need thechip-certexecutable in your system variable PATH. To
learn how to getchip-cert, go to the note at the end of
Creating a factory data partition with the second script
section, and then add the newly built executable to the system variable PATH.
The Cmake build system will find this executable automatically.
After that, use the following command from the example's directory to write
firmware and newly generated factory data at the same time:
west flashThe factory data generation process described above
is only an example valid for the Telink platform. You can well create a HEX
file containing all Factory data component table in any
format and then implement a parser to read out all parameters and pass them to a
provider. Each manufacturer can implement a factory data set on its own by
implementing a parser and a factory data accessor inside the Matter stack. Use
the Telink Provider
and FactoryDataParser as
examples.
You can read the factory data set from the device's flash memory in different
ways, depending on the purpose and the format. In the Telink example, the
factory data is stored in the CBOR format. The device uses the
Factory Data Parser to read
out raw data, decode it, and store it in the FactoryData structure. The
Factor Data Provider
implementation uses this parser to get all needed factory data parameters and
provide them to the Matter core.
In the Telink example, the FactoryDataProvider is a template class that
inherits from DeviceAttestationCredentialsProvider,
CommissionableDataProvider, and DeviceInstanceInfoProvider classes. Your
custom implementation must also inherit from these classes and implement their
functions to get all factory data parameters from the device's flash memory.
These classes are virtual and need to be overridden by the derived class. To
override the inherited classes, complete the following steps:
Override the following methods:
// ===== Members functions that implement the DeviceAttestationCredentialsProvider
CHIP_ERROR GetCertificationDeclaration(MutableByteSpan & outBuffer) override;
CHIP_ERROR GetFirmwareInformation(MutableByteSpan & out_firmware_info_buffer) override;
CHIP_ERROR GetDeviceAttestationCert(MutableByteSpan & outBuffer) override;
CHIP_ERROR GetProductAttestationIntermediateCert(MutableByteSpan & outBuffer) override;
CHIP_ERROR SignWithDeviceAttestationKey(const ByteSpan & messageToSign, MutableByteSpan & outSignBuffer) override;
// ===== Members functions that implement the CommissionableDataProvider
CHIP_ERROR GetSetupDiscriminator(uint16_t & setupDiscriminator) override;
CHIP_ERROR SetSetupDiscriminator(uint16_t setupDiscriminator) override;
CHIP_ERROR GetSpake2pIterationCount(uint32_t & iterationCount) override;
CHIP_ERROR GetSpake2pSalt(MutableByteSpan & saltBuf) override;
CHIP_ERROR GetSpake2pVerifier(MutableByteSpan & verifierBuf, size_t & verifierLen) override;
CHIP_ERROR GetSetupPasscode(uint32_t & setupPasscode) override;
CHIP_ERROR SetSetupPasscode(uint32_t setupPasscode) override;
// ===== Members functions that implement the DeviceInstanceInfoProvider
CHIP_ERROR GetVendorName(char * buf, size_t bufSize) override;
CHIP_ERROR GetVendorId(uint16_t & vendorId) override;
CHIP_ERROR GetProductName(char * buf, size_t bufSize) override;
CHIP_ERROR GetProductId(uint16_t & productId) override;
CHIP_ERROR GetSerialNumber(char * buf, size_t bufSize) override;
CHIP_ERROR GetManufacturingDate(uint16_t & year, uint8_t & month, uint8_t & day) override;
CHIP_ERROR GetHardwareVersion(uint16_t & hardwareVersion) override;
CHIP_ERROR GetHardwareVersionString(char * buf, size_t bufSize) override;
CHIP_ERROR GetRotatingDeviceIdUniqueId(MutableByteSpan & uniqueIdSpan) override;Move the newly created parser and provider files to your project directory.
Add the files to the CMakeList.txt file.
Disable building both the default and the Telink implementations of
factory data providers to start using your own implementation of factory data
parser and provider. This can be done in one of the following ways:
