Performing a key agreement recovery procedure

An initiator device and a target device may be configured to communicate with each other based on an anonymous key agreement procedure and an associated key agreement procedure. The anonymous key agreement procedure is performed for an initial communication session between the devices based on bonding identifiers (BIs) received in an attribute request/response. The BIs may be maintained by the devices to forego the anonymous key agreement procedure for subsequent communication sessions, where the devices may instead communicate based on an associated key agreement procedure. In cases where BIs are changed or lost by one of the devices, the associated key agreement procedure may not be performed and the anonymous key agreement procedure may be again attempted by the device. The other device is configured to determine that the anonymous key agreement procedure is being attempted and complete the anonymous key agreement procedure in an anonymous mode.
