STM32WB55 no longer supported in X-Cube-Matter v1.5.0

Hi ST Team,

I just downloaded X-Cube-Matter package v1.5.0 and noticed that support for STM32WB55 uC was entirely removed, without even being mentioned in the release notes. Why is that? Is the uC being discontinued?

Where can I find updated Matter examples for STM32WB55?

Thanks

Hello @AViva.1 

It seems that ST is focusing on the Matter support for the STM32WBA6 that does include up to 2 Mbytes. If you are looking for Matter support for the STM32WB, you should use previous version (X-Cube-Matter V1.4.2).

Best Regards.

Thanks for your suggestion, however I’m already using v1.4.2 and I wanted to upgrade to v1.5.0

Honestly it seems that ST is totally giving up on Matter. Not only their wireless stack is a total nightmare to implement, especially if compared to their competitors’, now they’re also removing examples for uCs that are still in the active lifecycle and still advertised as supporting Matter, without even bothering to mention it in the release notes…

If ST wants to recover shares in the IoT field, they better change their approach…
