The Texas Instruments Matter platform is based on the TI SimpleLink™ SDK.
The following diagram is a simplified representation of a Matter application which is built on the TI Platform.
This Texas Instruments Matter GitHub repository contains the software development components and tools that enable engineers to develop Matter based products. This repository is the starting point for Matter development on all SimpleLink Thread and Wi-Fi wireless microcontrollers (MCUs).
The SimpleLink MCU portfolio offers a single development environment that delivers flexible hardware, software, and tool options for customers developing wired and wireless applications. With 100 percent code reuse across host MCUs, Wi-Fi™, Bluetooth Low Energy, 2.4GHz, Sub-1GHz devices and more, choose the MCU or connectivity standard that fits your design. A one-time investment with the SimpleLink software development kit allows you to reuse often, opening the door to create unlimited applications. For more information, visit www.ti.com/simplelink.
In the TI example applications the Bluetooth Low Energy protocol is used to provision the Thread protocol to enable Matter communication. Then Thread is used for IP communication with other Matter devices.
The TI applications leverage the Bluetooth Low Energy stack on the CC13XX and CC26XX families. This Bluetooth LE software is distributed in binary form within the TI SimpleLink SDK. The Bluetooth LE stack leverages code that is present in the device ROM for certain common Bluetooth LE operations.
These applications leverage the OpenThread stack available within the Matter repository for Thread communication. Platform support source is built from the SimpleLink SDK.
These connection protocols can be run concurrently by using the Texas Instruments Dynamic Multi-protocol Manager.
The Lightweight IP stack interfaces with the OpenThread stack to offer standard IP connectivity protocols that OpenThread does not natively support. This offers a standard socket based interface to the Matter platform.
The MbedTLS library is used by OpenThread and Matter for a wide variety of protocols. This ranges from basic AES and SHA to cryptographic protocols like ECDSA and ECDH.
The MbedTLS library is hardware accelerated using the TI SimpleLink SDK drivers.
This is achieved through the usage of _ALT defines in the MbedTLS
configuration file.
Matter Stack interacts with LwIP, OpenThread, and the TI-BLE stack to achieve the protocol and application functionality. A Bluetooth LE profile is registered with the TI-BLE stack to enable provisioning and configuration. Once the device is provisioned Matter will configure the OpenThread interface to connect to an existing Thread network or to start its own network. From there the Matter IP messages are sent to the LwIP stack to be routed to the OpenThread stack for transmission. Matter Impl (Implementation) layer acts as an interface between Matter stack and the TI platform components such as BLE stack, OpenThread, FreeRTOS. It also supports components such as connectivity manager that provides the implementation for functionality required by Matter stack. Overall, applications generally only need to interface with the Cluster Library from Matter. The transport of messages and configuration of the device is all handled by the platform implementation files.

Sample Matter applications are provided for the TI platform. These can be used as reference for your own application.
The TI platform uses GN to generate ninja build scripts. Build files have already been written to build and link the TI specific code within the SimpleLink SDK.
