Failedto customize Cluster as per document

Hello, Nordic Team!

I followed this document and used the XML file mentioned in the document. custom_clusters

I did regenerate the files under the zap-generated folder, but the ExtendedCommandResponse in MyCluster.xml was not generated, which caused the compilation error.

Here are my steps:

1. Copy the Mycluster.xml file from the document and place it under src/default_zap in project directory.

2. Copy the file `ncs/v3.0.0-rc1/modules/lib/matter/src/app/zap-templates/zcl/zcl.json` to the `src/default_zap` directory in project.

3. west zap-append -o src/default_zap/zcl.json src/default_zap/MyCluster.xml

4. west zap-gui -j src/default_zap/zcl.json --clusters src/default_zap/MyCluster.xml

5. west zap-generate --full

I didn't modify any code.

ncs 3.0.0, nrf54l15dk

Hi,

If ExtendedCommandResponse is not generated, it is most likely missing from the XML file. I see that the example XML in the documentation is missing this.

Here is an example of how to implement it:

<command source="server" code="0x01" name="ExtendedCommandResponse" optional="false" disableDefaultResponse="true">
   <description>Response to ExtendedCommand.</description>
   <arg name="arg1" type="int8u"/>
</command>

And this is what the complete MyCluster.xml will look like with this included:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<configurator>
   <cluster>
      <domain>General</domain>
      <name>MyNewCluster</name>
      <code>0xFFF1FC01</code>
      <define>MY_NEW_CLUSTER</define>
      <description>The MyNewCluster cluster showcases a cluster manufacturer extensions</description>
      <attribute side="server" code="0xFFF10000" define="MY_ATTRIBUTE" type="boolean" writable="true" default="false" optional="false">MyAttribute</attribute>
      <command source="client" code="0xFFF10000" name="MyCommand" optional="false">
         <description>Command that takes two uint8 arguments and returns their sum.</description>
         <arg name="arg1" type="int8u"/>
         <arg name="arg2" type="int8u"/>
      </command>
      <event side="server" code="0xFFF10000" name="MyEvent" priority="info" optional="false">
         <description>Event that is generated by the server.</description>
         <arg name="arg1" type="int8u"/>
      </event>
   </cluster>
   <clusterExtension code="0x0028">
      <attribute side="server" code="0x17" define="EXTENDED_ATTRIBUTE" type="boolean" writable="true" default="false" optional="false">ExtendedAttribute</attribute>
      <command source="client" code="0x00" name="ExtendedCommand" response="ExtendedCommandResponse" optional="false">
         <description>Command that takes two uint8 arguments and returns their sum.</description>
         <arg name="arg1" type="int8u"/>
         <arg name="arg2" type="int8u"/>
      </command>
      <command source="server" code="0x01" name="ExtendedCommandResponse" optional="false" disableDefaultResponse="true">
         <description>Response to ExtendedCommand.</description>
         <arg name="arg1" type="int8u"/>
      </command>
      <event side="server" code="0x04" name="ExtendedEvent" priority="info" optional="false">
         <description>Event that is generated by the server.</description>
         <arg name="arg1" type="int8u"/>
      </event>
   </clusterExtension>
   <enum name="MyNewEnum" type="int8u">
      <cluster code="0xFFF1FC01" />
      <item name="EnumValue1" value="0" />
      <item name="EnumValue2" value="1" />
   </enum>
   <struct name="MyStruct" isFabricScoped="true">
      <cluster code="0xFFF1FC01"/>
      <item fieldId="1" name="Data" type="octet_string" length="128" isFabricSensitive="true"/>
   </struct>
   <deviceType>
      <name>my-new-device</name>
      <domain>CHIP</domain>
      <typeName>My new device</typeName>
      <profileId editable="false">0x0104</profileId>
      <deviceId editable="false">0xfff10001</deviceId>
      <class>Simple</class>
      <scope>Endpoint</scope>
      <clusters lockOthers="true">
         <include cluster="MyNewCluster" client="true" server="true" clientLocked="false" serverLocked="false"/>
      </clusters>
   </deviceType>
</configurator>

I will notify the developers that ExtendedCommandResponse is missing from the example file.

Best regards,
Marte
