Features and platforms supported
The release is intended for developers who wish to start developing applications that use Matter over Thread, Matter over Wi-Fi, or Matter over Wi-Fi + Thread Border Router. To get started
read the following entry points of preconfigured application examples:
- K32W0 FreeRTOS - Matter over Thread (with Bluetooth LE commissioning):
- K32W1 FreeRTOS - Matter over Thread (with Bluetooth LE commissioning):
- MCXW 71 FreeRTOS - Matter over Thread (with Bluetooth LE commissioning):
- MCXW 72 FreeRTOS - Matter over Thread (with Bluetooth LE commissioning):
- RW61x FreeRTOS - Matter over Wi-Fi (with Bluetooth LE commissioning) or Matter over Thread (with Bluetooth LE commissioning) or Matter over Wi-Fi with OpenThread Border Router support (with Bluetooth LE commissioning). All applications support basic Thread Border Router features, but the Matter 1.4 TBRM and Secondary Network Interface clusters are only supported by the thermostat application.
