Pairing issue with Chip Tool v1.1.0.1 #18

Closed farshidtz closed 10 months ago

farshidtz commented 1 year ago

The chip-tool v1.1.0.1 has some difficulties in pairing with the matter-gpio-commander. The log shows a persisted storage error preventing the commissioning discovery over DNS-SD as follows:

CHIP:CTL: Couldn't get ExampleOpCredsCAKey from storage: src/controller/ExamplePersistentStorage.cpp:93: CHIP Error 0x000000A0: Value not found in the persisted storage

Full logs could be find here.

With the same setup as the matter-bridge-tapo-lighting, the chip-tool snapped from the edge channel was able to pair with it without any errors. The full logs can be found here.

chip-tool snap:

The issue gets resolved by upgrading the commander's SDK version to the same one used for the Chip Tool. See https://github.com/canonical/matter-pi-gpio-commander/pull/20

This is unexpected as the SDK v1.1.0.1 release supposed to be backward compatible.
