摘要： Apparatus, which has a multilayer protocol stack for processing incoming messages, determines PTT state from messages received from a peripheral over a wireless serial communication channel. The apparatus: receives (902), from the peripheral, a sequence of messages comprising a plurality of data messages (e.g., RFCOMM messages), wherein each of the data messages provides an indication of a PTT state for the apparatus, and wherein the sequence of data messages is received over a short range wireless data path for exchanging priority data that comprises a wireless serial communication channel and that is different from a short range wireless data path for exchanging non-priority data. A pattern detector in the apparatus performs (904) a pattern matching process, within the first two layers of the multilayer protocol stack, to determine the PTT state indicated by each of the data messages and sets (906) the apparatus to have the determined PTT states.

摘要： A first communication device (e.g., a radio) and a second communication device (e.g., an accessory) implement a wireless device pairing procedure to exchange numerical credentials so that the devices can subsequently form a link for communications using electromagnetic radio signals. The accessory transmits a beacon comprises a pairing request. Upon a user bringing the radio and accessory in close enough proximity, the radio receives the beacon using near-field apparatus included in the radio. In response to receiving the beacon, the radio initiates a pairing procedure, wherein the pairing procedure comprises a data exchange between the radio and accessory, and wherein the beacon and the data exchange comprise a non-propagating radio signal generated using the near-field apparatus. Upon completing the pairing procedure, the radio forms a link with the accessory to communicate using propagating electromagnetic radio signals.

摘要： Authentication methods are used to authenticate, a device1 having an ESN1 (electronic serial number), a device2 having an ESN2, and/or a user of the devices. In one implementation, device1 receives the ESN2 in a near-field signal; derives an authentication result as a function of the ESN1 and ESN2; and sends the authentication result to an authenticator device to use in completing authentication. Authentication is confirmed when the device1 authentication result matches an authentication result independently generated by the authenticator device, which is provisioned with the ESN1 and ESN2. In a second implementation, device1 generates a RAND1 (random number) and sends the RAND1 to device2 over a near-filed link. An authenticator device confirms authentication upon receiving the same RAND1 from both device1 and device2.
