6 months ago @oidebrett Maybe you can use SimplicityStudio as a workaround. The examples do not include a bridge. It works correctly in this case.
It works for Silicon Labs xG24 Explorer Kit but I am not sure it will work with Arduino Nano Matter board.

6 months ago Hello @oidebrett, This is by design - we use dynamic endpoints - so a bridge device was added on endpoint 2 to ensure compatibility with most ecosystems. Also, you can parametrize your chip-tool commands to look for the device on endpoint 3 and be able to interact. Endpoint 1 is used by a placeholder endpoint which is disabled during startup.

6 months ago Thanks for your reply. I am just starting my journey into Arduino nano matter development and I am using the Arduino IDE.
I have experience of using the ESp32 and I can write code using the Esp-idf to write code that implements endpoints, clusters etc.
Is there any documentation on how I could use the Arduino IDE to get a lower level of access to the matter data model and core functionality? For example if I don't want to use a bridge on endpoint 2 could I implement my own endpoints and clusters?
For example with ESP-idf I can use write code at this level
Sorry to be asking this in the repo. Is there a better place to get this information that is regularly responded to?
Many thanks

5 months ago Hello @oidebrett,
No worries, you're in the right place for asking questions. The bridge endpoint was introduced to ensure compatibility for the bridges/dynamic endpoints. In the future versions we'll introduce a way to turn it off, however in the meantime you can disable it with:
emberAfEndpointEnableDisable(emberAfEndpointFromIndex(1), false);
If you want to go a bit lower - take a look at the source of a device in the Matter library (like this and this) - those directly access the Matter SDK. You can create your own custom endpoints/devices in the same fashion.

Issue description
Shouldnt the OnOff cluster be on Endpoint 1 not Endpoint 3 in the Matter light example?
Is there a reason why the OnOff cluster for the Matter light example is on endpoint 3 rather than endpoint 1? see libraries/Matter/examples/matter_lightbulb/matter_lightbulb.ino
I am testing with the chip-tool and after pair I am trying to interact with the OnOff cluster. In most other Matter development platforms that primary device type clusters are on endpoint 1. But i have found that any matter example that I have tried from this repo the primary clusters are on Endpoint 3.
Am I missing something?
