Static OOB

[Bob J]

I have searched all of the three Bluetooth Mesh specifications and cannot find a definition for Static OOB. Could someone define what that is?

Take a look at this link. A bit more is explained here too: " In this case, the provisioner and unprovisioned device each generate a random number and then proceed to the check confirmation value operation."

Static OOB is the OOB that is pre-defined (mostly by your code). If the Provisioner and Provisionee both have the same Static OOB key, the authentication is succeeded. For example:

The Provisioner OOB Key is 0x11223344 and same for Provisionee. When they come to the authentication, they will exchange their OOB keys and check if the key each one receives matches the static OOB. If the received key and the static key matches, the authentication is succeeded otherwise it will fail.
