The following diagram is a simplified representation of a Matter application which is built on the TI SimpleLink Platform.
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 interacts with LwIP, Mbed TLS, and the NWP to achieve the protocol and application functionality. Through using LWIP though Ethernet I/F (SL in Network-Bypass mode) enables provisioning and commission. Once the device is provisioned the Matter IP messages are sent to the LwIP stack to be routed to the Wi-Fi NWP for transmission.
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 SimpleLink platform. These can be used as reference for your own application.
See the Matter lock-app on Wi-Fi to get started with Matter on SimpleLink Wi-Fi devices.
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.
