摘要:
Aspects disclosed herein relate to providing peer communications between NFC enabled devices using an active communication mode. In one example, a communications device is equipped to detect a remote NFC device field within an operating volume, establish a peer communication link with the remote NFC device using an active communication mode, determine that the peer communication link is to be deselected, and transmit a deselection request message to the remote NFC device indicating to the remote NFC device that it has been deselected while maintaining the peer communication link. In another example, a communications device is equipped to sense an operating volume, as part of an active communication mode collision avoidance procedure, determine that no field is sensed, initiate an unmodulated carrier as part of switching an operating field to an on state, and maintain the unmodulated carrier for a collision avoidance threshold duration of time.
