hi,

Thank you for your answers. Everything is clearer. I've the same behavior in my board.

Best regards.

Hi,

I am not sure I understand what your end goal is.

[quote user="samrou"]"The PartsList of the Descriptor cluster on the root node endpoint SHALL list all endpoints on the node, except the root node endpoint". In my case i have two more endpoint that rootnode endpoint.[/quote]

This is already done automatically. If you add more endpoints to the device, the endpoints will automatically be added to the PartsList of the Root Node descriptor. For example, on this device I have added two additional endpoints, endpoint 1 and 2:

If I read the PartsList attribute of the root node, e.g. using chip-tool, I get the following:

As you can see, endpoint 1 and 2 shows up there.

If you want more information about a specific endpoint, you can read the attributes from the Descriptor cluster of the specific endpoint.

Best regards,
Marte

of course it's done autamtically, but the Matter Specification Version 1.0 document say that p450 "The PartsList of the Descriptor cluster on the root node endpoint SHALL list all endpoints on the node, except the root node endpoint". In my case i have two more endpoint that rootnode endpoint.

So i need to specify that in the descriptor cluster of the root node, and i can't.

Hi,

Maria is out of the office, so I have taken over your ticket.

The DeviceTypeList attribute contains a list of supported device types, not clusters, and it shows the supported device types on that specific endpoint.

When adding the Power Source cluster, did you do this by adding a Matter Power Source device on an endpoint, or by adding the cluster to a different device? If you create an endpoint with a Matter Power Source device, then you can use the descriptor on that endpoint instead.

Best regards,
Marte

Hello, i have already done that but i want to modify devicetypelist attribute of descriptor cluster, and i can't.

Neither by zap no by code.

Zap doesn't allow array, return invalid integer out of range.

by code :

const EmberAfDeviceType PowerSourceDeviceTypes[] ={{0x0016,1},{0x0011,1}}; 
emberAfSetDeviceTypeList(0, (Span<const EmberAfDeviceType>(PowerSourceDeviceTypes,2)));

//also try
//emberAfSetDeviceTypeList(0, Span<const EmberAfDeviceType>(PowerSourceDeviceTypes));

in chip-tool-debug :

chip-tool-debug descriptor read device-type-list 1 0

well return an array of 2 devicetypestruct (with devicetype and revision), but the value are not 0x16 and 0x1, there are the max value 0xFFFF and 0xFF for the 2 devicetype in the list.

Hello,

You can add new endpoints with their own device type by using the ZAP tool. Is this what you are trying to do?

One step which is not included in the documentation is that the ZAP tool should be opened with the run_zaptool.sh script found at <ncs-installation>/modules/lib/matter/scripts/tools/zap.

Best regards.

So is there any solution to modfify the array to have 2 or more devicetype struc element in the list ?

Hello,

i use the nRF Connect SDK v2.2.0 for matter 1.0.

I begin with nrf/mattet/template after having try to modify /mnrf/matter/lock.

Even if all part of my matter application work, i try to compare with other example lock, light_bulb, light_switch to see if they have a devicetypelist greater than 1.

I'm successfully use zap to modify all my need (create 2 more endpoint that root, with cluster) and all is well working.

But impossible to add more than one devicetype in the list in the descriptor cluster of the root node

Hello,

I will help you with this. Please provide the following information:

Which nRF Connect SDK version are you using?

Are you using a Matter sample as a basis?

Have you read our documentation on the ZAP tool, and how to add and edit clusters in your Matter application?

Best regards,

Maria
