Abstract: A wireless headset includes first and second wireless earphone devices, each including a microphone. The first earphone device assembles a first group of audio packets, each of which includes a first low-resolution clock value, a first high-resolution clock value, and a sequence of first microphone samples, and transmits the first plurality of audio packets to the second wireless earphone device, as a slave device of a first wireless network. The second earphone device receives the first group of audio packets from the first wireless earphone device, assembles a second group of audio packets, each of which includes a second low-resolution clock value, a second high-resolution clock value, and a sequence of second microphone samples, and transmits the first and second groups of audio packets to an external device. Other aspects are also described and claimed.

Abstract: A first device may communicate via a first wireless interface (WI) and a second WI, with the second WI operating at a relatively higher power level than the first WI. The first device may receive a scan notification corresponding to wireless scanning performed by a second device. The first device may subsequently perform wireless scanning using the second WI in response to the scan notification indicating that the first device is within effective communication range of a third device. The first device may receive the scan notification over a wireless connection established between the first device and the second device using the first WI. The first device may transmit filter information to the second device, the filter information indicating when, and for which scans the first device is to receive scan notifications. The first device may also activate the second WI and use the second WI to perform ranging and/or control operations associated with the third device.

Abstract: In order to reduce the power consumption after a transmitting electronic device in a wireless network has been detected, a receiving electronic device calculates transmit times of subsequent beacons from the transmitting electronic device based on a clock drift of the transmitting electronic device and the beacon period. Then, the receiving electronic device receives the subsequent beacon by opening scan windows that encompass the calculated transmit times. However, because the transmit times are more predictable after the transmitting electronic device has been detected (and the clock drift of the transmitting electronic device is known to the receiving electronic device), the receiving electronic device can reduce the width of the scan windows. In addition, the transmitting electronic device can further reduce the power consumption by increasing the beacon period.

Abstract: A method and system for an improved communication mode for Bluetooth wireless devices is disclosed. Packets used in the improved communication mode are encoded using a convolutional encoder and transmitted with a particular modulation index such that the improved communication mode provides an improved link margin with respect to a communication mode specified in a Bluetooth wireless communication protocol. In this regard, the improved communication mode allows Bluetooth wireless devices to continue to communicate when a communication link between the Bluetooth wireless devices degrades, whereas otherwise the connection would be dropped. Furthermore, the Bluetooth wireless devices seamlessly switch between the improved communication mode and other Bluetooth communication modes without renegotiating the connection.

Abstract translation: 公开了一种用于蓝牙无线设备的改进的通信模式的方法和系统。 在改进的通信模式中使用的分组使用卷积编码器进行编码，并以特定的调制索引进行传输，使得改进的通信模式相对于蓝牙无线通信协议中指定的通信模式提供了改进的链路余量。 在这方面，当蓝牙无线设备之间的通信链路降级时，改进的通信模式允许蓝牙无线设备继续通信，否则连接将被丢弃。 此外，蓝牙无线设备在改进的通信模式和其他蓝牙通信模式之间无缝地切换，而不重新协商连接。
