studying Matter

[jhc]

Hi,

I am learning Matter. I have some questions:

1. Where can I get the resources, especially official resources, to study Matter?
2. What is the use of the Service discovery in Matter? Is there any service implemented in Matter itself?
3. What is the relationship and difference between the Access Control cluster and the Binding cluster in Endpoint 0?
4. Is the Subscription function implemented by Binding through the Binging cluster?
5. Does the Binding process have to be carried out by the Admin node?
6. Does the Admin of the network have a default permission to access the ACL of other Matter devices?

Thanks in advance for any help.

Hi,

Where can I get the resources, especially official resources, to study Matter?

To get access to the Matter specification, you should become a member of the Connectivity Standard Alliance (CSA). You can find the available documentation from Nordic in the nRF Connect SDK documentation:

• Matter
• Matter Documentation

What is the use of the Service discovery in Matter? Is there any service implemented in Matter itself?

The Matter specification defines supported clusters, which representation of a single functionality within a Matter device, such as turning a device on and off. Each cluster contains attributes, commands, and events, which can be mandatory or optional.

• What is the relationship and difference between the Access Control cluster and the Binding cluster in Endpoint 0?
• Is the Subscription function implemented by Binding through the Binging cluster?
• Does the Binding process have to be carried out by the Admin node?
• Does the Admin of the network have a default permission to access the ACL of other Matter devices?

I will have to check with our Matter team regarding these questions.

Best regards,
Jørgen
