1. A method for scheduled access via an access control mechanism, the method comprising:
by a first wireless device:
obtaining an ephemeral identity resolving key (IRK) that is valid only during a scheduled time period;
receiving, during the scheduled time period from a second wireless device that comprises the access control mechanism, an ephemeral resolvable private address (RPA) based on the ephemeral IRK;
deriving a Bluetooth address of the second wireless device using the ephemeral IRK and the ephemeral RPA; and
transmitting, during the scheduled time period and using the Bluetooth address, an access request to the second wireless device, requesting the access control mechanism to grant access.
