摘要： Systems, methods, and devices predict activity of wireless devices. Methods include identifying one or more conditions indicating aperiodic activity will occur at a first radio, the first radio being a wireless radio compatible with a first wireless communications protocol, and receiving, at a second radio, timing information associated with the first radio via an interface between the first radio and the second radio, the second radio being a wireless radio compatible with a second wireless communications protocol, the first radio and the second radio being collocated in a wireless device. Methods also include scheduling wireless activity of the second radio based, at least in part, on the timing information.

摘要： A system and method for improving the accuracy of a secure phase-based ranging procedure and a Direction Finding procedure. The method includes receiving radio frequency signals from a second communication device. The method includes operating in a first mode including generating first location data based on the radio frequency signals and, transferring the first location data to a second processor in compliance with a Bluetooth Host Control Interface. The method includes comparing one or more conditions to one or more threshold values and responsive to the comparing transitioning from operating in the first mode to operating in a second mode. The method includes, while operating the second mode, generating second location data based on the radio frequency signals and, transferring the second location data to the second processor at a higher data transfer rate than the transferring of the first location data to the second processor.

摘要： Disclosed are techniques for a device that wants to be a central device when creating a connection in a communication network such as Bluetooth Low Energy (BLE) to advertise information associated with a connection window to solicit a connection with a scanning peer device. When the scanning peer device receives the information, it may enter a connection as a peripheral device with the advertising device at the advertised connection window, allowing the advertising device to become the central device. Disclosed are also techniques for a device that wants to be a central device to advertise information associated with a scan window of the device to solicit a directed advertisement event from a peer device during the advertised scan window. The peer device initially scans but may advertise during the scan window as advertised to enable the central device to create a connection where the peer device becomes a peripheral device.
