Hi

@grobasoz
Can I ask you how to build Matter samples for the the XIAO nRF52840 board?
I have been trying to compile the examples for over a year.

Regards

I use the standard settings for the Matter examples.
So create a project from the example (eg Matter Light), then create a Build Configuration.
Select SDK (3.1.0)
Toolchain (3.1.0)
Target (nrf52840)
Base confg (prj.conf)
Extra Kconfig (mcuboot)
Optimize (debug)
Generate and Build
Debug with Ozone (flashes as well over Segger SWD).
From the serial monitor, grab the QRCode URL.

Using Apple Homekit (or Google Nest, or Home Assistant), add the device to your Matter fabric.
Select Add Anyway for “uncertified” device.

Where can I found toolchain 3.1.0? I don’t see it in the list:

Sorry - toolchain is 3.0.2 in my dropdown (typo?) :stuck_out_tongue:

But…

It’s strange, those different versions.
Did you build it for nRF52840-DK or XIAO BLE nRF52840?

I build and run on DK (I don’t use XIAO NRF parts).

I know that it works with the DK because Nordic supports it.
