STM32WB5MM-DK unable to connect over Matter

RHeyse

I am attempting to use the https://github.com/stm32-hotspot/stm32wb-matter-device-over-thread/ repo to connect a STM32WB5MMG-DK to an Amazon Alexa acting as a border router, using the Alexa app. The device always fails to connect, outputting the serial log that I have attached. I am using the recommended firmware (stm32wb5x_BLE_Thread_ForMatter_fw.bin)

I have also been unable to commission using the CHIP-TOOL and Raspberry Pi 5 border router.

Hello @RHeyse,

Indeed, the version of matter package available on Github Hotspot does not support Amazon Alexa, a new version will be available very soon that supports a wide range of ecosystems.

If your request is of a professional nature, please contact your ST local representative to get the latest version of the package, for more details :

On the other side, the version available on Github is compatible with Raspberry Pi and should be working, do you have any logs capture to further analyze your case ?

Hi Ouadi,

Thanks for the heads up, I'll make sure to get in touch with them as I also need to be able to support Apple and Google home assistants.

I don't have any logs at the moment unfortunately, but my current main issue is when attempting to commission the device using the android chip-tool app, the app crashes without any error message. I've also tried running the tool on Ubuntu 22.04, but i get an error about the device pin number.

Hello @RHeyse,

The crash of the android app is a known issue, for that you have to clear the CHIPTool cache after each commissioning and make sure to use the right QR code.

Kind regards,

Ouadi
