Abstract: Devices at either end of a wireless communication link are each configured to support multiple different link settings. During communication, a device that is receiving data can monitor the signal quality and initiate a dynamic transition to a new link setting if performance of the current link setting falls below a lower threshold or exceeds an upper threshold. Dynamic link adaptation can be implemented within a wireless communication interface of the device and can be transparent to application and/or operating system software executing on the device.

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 may depend on a battery power level of the electronic device. However, the selective increase in the transmit power level may decrease the overall power consumption by reducing or eliminating retries.
