Abstract: A method for adjusting an RF amplifier is provided. The method includes determining link statistics corresponding to wireless data received by a first device. The wireless data was transmitted by a second device, such as via a Bluetooth protocol. The method further includes adjusting an RF amplifier of the first device or the second device based on the one or more link statistics. The one or more link statistics may include RSSI, PER, buffer level, audio drop data, and acknowledgement packet data. The RF amplifier may be a low noise amplifier or a power amplifier. The adjusting may include increasing or decreasing a gain of the RF amplifier. Alternatively, the adjusting may include activating or deactivating the RF amplifier.

Abstract: Methods and systems of acknowledgment of wireless data packets is provided. For example, such a method can include receiving, from a central device, such as a smartphone, at a first peripheral device, such as a left earbud, a first isochronous data stream intended to be received by the first peripheral device. The method further includes receiving, from a central device at a second peripheral device, such as a right earbud, a second isochronous data stream intended to be received by the second peripheral device. In some examples, the second peripheral device is a right earbud. The method further includes eavesdropping, via the second peripheral device, the first isochronous data stream in an attempt to receive a packet of the first isochronous data stream. The method further includes sending, from the second peripheral device, an acknowledgment after the packet has been received by the second peripheral device.

Abstract: Systems, devices, and methods for initiating an action based on location of a first device are provided. The first device, such as an earbud, includes a Bluetooth receiver. The Bluetooth receiver is configured to receive a wave signal transmitted by a second device, such as a smartphone. The first device further includes a processor. The processor is configured to calculate a location of the first device relative to the second device based on the wave signal. The processor is further configured to determine a zone status of the first device based on the location of the first device relative to the second device and a predetermined zone. The processor is further configured to initiate the action based on the zone status.

Abstract: A method and apparatus for communicating streaming data in a Bluetooth-based wireless communication system is provided. An electronic device according to the present disclosure includes a communication interface configured to perform wireless Bluetooth communication with an external electronic device and a controller configured to control the communication interface, in which the controller is further configured to detect a communication state using a first packet data configuration and communicate with the external electronic device by using a second packet data configuration that is different from the first packet data configuration, based on the communication state.
