Abstract: A device implementing a system for NFC communication includes a processor configured to receive, from an other device, pulse signals for detecting proximity of the device with the other device. The processor is further configured to determine an interval at which the pulse signals are received from the other device. The processor is further configured to determine a time when the other device is expected to transmit a subsequent pulse signal based at least in part on the determined interval. The processor is further configured to transmit a signal to the other device based on the determined time when the other device is expected to transmit the subsequent pulse signal.

Abstract: Exemplary embodiments include a system having a first wireless audio output device and a second wireless audio output device. One of the first or second audio output devices is configured to one of connect as a slave to a source device in a first piconet and connect as a master to the other one of the first or second audio output devices in a second piconet. The one of the first or second wireless audio output devices determines whether an audio packet transmitted by the source device via the first piconet was received by the first wireless audio output device and the second wireless audio output device, and, when at least one of the first wireless audio output device or the second wireless audio output device did not receive the audio packet, the audio packet is exchanged between the first and second wireless audio output devices via the second piconet.

Abstract: This application relates to systems, methods, and apparatus for testing operability of a mobile device with a reader device. In some embodiments, a testing system is set forth for automatically placing the mobile device proximate to the reader device in order to initiate a wireless transaction between the mobile device and the reader device. Depending on whether the mobile device is determined to be operable with the reader device, the testing system can automatically place the mobile device proximate to another reader device for testing. In this way, reductions in testing time can be manifested as a result of automating the testing process.

Abstract: In order to improve communication with another electronic device, during an advertising mode an electronic device (such as a smartphone) may transmit a packet with advertising information using a default transmit power level. Then, based on feedback about a performance metric associated with the communication from the other electronic device, the electronic device may selectively increase the transmit power level for a subsequent packet. Because this selective increase in the transmit power level may increase the overall power consumption, the change in the transmit power level also may depend on one or more factors, such as a battery power level of the electronic device. However, the selective increase in the transmit power level may, in some instances, decrease the overall power consumption by reducing or eliminating retries.
