Hi,
I am testing your light_switch and light_bulb matter samples and in particular the group interactions of devices in a group.
I have this setup:
- CHIP Tool running on Ubuntu LTS 22.04;
- One Raspberry Pi 4 as Openthread Border Router built from openthread/ot-br-posix github project;
- One nrf52840dk flashed with the openthread/rcp sample, connected to the Border Router;
- One nrf52840dk flashed with your light_switch sample;
- Multiple nrf52840dk flashed with your light_bulb sample.
I added all light_bulbs and light_switch to a group and created the binding required bind betweenthe group and onoff commands (followinng https://github.com/project-chip/connectedhomeip/blob/master/examples/light-switch-app/nrfconnect/README.md#group-multicast-binding-to-the-group-of-remote-endpoints-using-the-chip-tool-for-windows-or-linux,)
I noticed from logs that the reception of the command from group bind is not notified and so it seems not possible for the light_switch to know if some device received it.
From coordinator (chip-tool), subscribing to the attribute change is possible to get it.
Is there something similar that can be implemented in the light_switch?
