How to Only Reset Matter and Matter related nvs data (CON-1529)

[bilalahmaddev]

Is there any API to reset Matter only and Matter related nvs Data?

[shubhamdp]

Can you elaborate more on "only reset matter and matter related nvs data"? Do you mean to only erase the matter specific data? Or are you expecting anything more?

esp_matter::factory_reset(), only erases the Matter specific data, but this resets the device (i.e. reboot).

@shubhamdp I am using same API when I flash code first time and run TC-RR-1.1 it passes the test and next time when I perform factory reset using this API esp_matter::factory_reset(), test case fails on timeout error on step 14.

Can you please try this, replace the ConfigurationMgr().InitiateFactoryReset(); with chip::Server::GetInScheduleFactoryReset() here https://github.com/espressif/esp-matter/blob/main/components/esp_matter/esp_matter_core.cpp#L894.

Below patch does the same...
