Hi,

The screenshot is from the ZigBee Cluster Library specification (ZCL) v7, which can be obtained from the Connectivity Standard Alliances (formerly known as the Zigbee alliance) pages: https://csa-iot.org/developer-resource/specifications-download-request/. You might need to become an adopter member to get access to the documentation, which should only be a matter of registration and not require any fees.

I know that version 7 is what we support in our SDK, and I'm investigating if we're supporting v8 at this point in time.

Kind regards,
Andreas

Hi,

[quote user=""]Does ZBOSS support manufacturer specific attribute extension to standard clusters?[/quote]

Yes, this is supported in the ZBOSS stack
,

[quote user=""]How about implementation of manufacturer specific clusters?[/quote]

You should be able to do so by adding extra attributes to an existing cluster. But you will have to create a new cluster list, so in for instance on/off cluster, you have ZB_ZCL_DECLARE_ON_OFF_ATTR_LIST, but you will have to add your own ZB_ZCL_DECLARE_ON_OFF_ATTR_LIST_CUSTOM and add your attributes there. You will also have to set the field that allows for manufacturer specific lists, as highlighted here: github.com/.../zb_dimmable_light.h

[quote user=""]Are there examples one can follow?[/quote]

When it comes to sample we don't have any official samples that illustrates how to add manufacturer attributes to standard clusters, but I recommend you start with the relatively simple on/off clusters in the light/light switch samples.

If you're using nRF 5 SDK for Zigbee and Thread: https://infocenter.nordicsemi.com/topic/sdk_tz_v4.2.0/examples_zigbee.html

If you're using nRF Connect SDK: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/samples_zigbee.html
