Error on commissioning step 'AttestationVerification': 'Error CHIP:0x000000AC' (CON-1473)

[stefano055415]

Hi, I'm trying to commission a matter device with the controller example.

I tried first using the light example as a device and everything works fine.

I then tried to commission a certified device and I get the error Error on commissioning step 'AttestationVerification': 'Error CHIP:0x000000AC'

I understood that the problem is the test certificate that I am using in the controller, but I wanted to ask if it was possible to bypass this check and still conclude the commissioning at least for this first test phase

@stefano055415 , in case you want to bypass the attestation verification, you can use --bypass-attestation-verifier in chip-tool which intends to continue commissioning in case of attestation failure.
The command chip-tool pairing ble-wifi --help will provide you a description of the option as shown below:
--bypass-attestation-verifier: Bypass the attestation verifier. If not provided or false, the attestation verifier is not bypassed. If true, the commissioning will continue in case of attestation verification failure.

@shripad621git

ok with chip-tool I can use the bypass, but with the example of the controller how do I do it?

The device is certified but the controller is not

@stefano055415 , can you please follow the instructions here using the Attestation Trust Store - Spiffs and copying the
production certs from ${ESP_MATTER_PATH}/connectedhomeip/connectedhomeip/credentials/production/paa-root-certs/*.der to paa_cert directory.
We will implement the main net DCL PAA cert fetching logic in the controller.
