Features and NXP platforms supported
The release is intended for developers who wish to start developing an
application that use matter over thread or matter over wifi. To get started
read the following:
- K32W0 - Matter over Thread (with BLE commissioning support):
Main changes in this release:
- K32W0
- Updated ICD parameters.
- Fixed a bug in OTA TLV processor, where OTA was failing if the transferred image was a multiple of BDX block size.
- Added an extra CRC verification for factory data OTA update.
- Changed root node revision to 2 for reference apps.
- Removed old custom factory data provider implementation. An alternative example is provided.
- Added support for Product Appearance attribute.
- Fixed a bug which caused the device to no longer enter low power after commissioning.
- Minor readme updates: provide clarifications related to SDK retrieval when building the reference apps. There are two ways to retrieve the SDK: through west tool, which will download the latest SDK released on https://github.com/nxp-mcuxpresso/mcux-sdk, or through downloading an SDK package.
Known issues and limitations
Sometimes, the OTA process might fail due to some retransmission failure of a BDX packet. This has a low probability, but it might be related to the specific Matter version used for the commissioner and OTA provider. Please take this into account. Nevertheless, the OTA should be successful after a device reset.
