The apparatus may establish a non-proprietary link layer connection with a second device. The apparatus may determine if a first set of empty non-proprietary link layer PDUs are exchanged with the second device via one or more channels during a non-proprietary link layer connection event. The apparatus may exchange proprietary establishment PDUs with the second device during at least one proprietary link establishment event via the one or more channels when it is determined that the first set of empty non-proprietary link layer PDUs are exchanged with the second device via the one or more channels. The apparatus may establish a proprietary link layer connection with the second device when it is determined that a sequence of the proprietary establishment PDUs have been exchanged with the second device. The apparatus may communicate with the second device via the proprietary link layer connection.
