Problem

It was raised in #15362 that passcode ID handling was incorrect and ambiguous for multi-admin. This led to spec issue https://github.com/CHIP-Specifications/connectedhomeip-spec/issues/4969, which was resolved by https://github.com/CHIP-Specifications/connectedhomeip-spec/pull/4972.

The outcome of all of this is:

  • When opening an ECM window, the passcodeID to use in PASE PBKDFParamRequest needs to always be 0.
  • Non-zero values of passcodeID in PASE PBKDFParamRequest are forbidden
  • PasscodeId field in OpenCommissioningWindow command needs to be removed
