Abstract: A method for operating a first radio of a number of radios within a radio frequency system may include sending a first command to the first radio of the plurality of radios to initiate an antenna sector level sweep and determining a first set of metrics associated with a first set of signals from other radios of the plurality of radios that correspond to the antenna sector level sweep. The method may also include receiving a second set of metrics associated with the first set of signals from a responder electronic device and identifying a sector of a number of sectors associated with the antenna sector level sweep based on the first set of metrics and the second set of metrics. The method may then involve sending a second command to the first radio to transmit data to the responder device via the identified sector.

Abstract: Systems, methods, and devices are provided for performing an antenna sector level sweep of a radio in a radio frequency system with co-existence of other radios. The method may involve sending a first command to a portion of a plurality of radios to determine a first set of signal quality metrics associated with the portion of the plurality of radios for one or more sectors of an antenna while the first radio is not active. The method may involve determining a second set of signal quality metrics associated with using the portion of the plurality of radios when the first radio is active via one or more sectors of a sector level sweep. The method also include generating a table that includes the second set of signal quality metrics and storing the table that indicates a portion of the sectors to avoid when the first radio performs a subsequent sweep.

Abstract: An input device, such as a stylus, can include a main body comprising a main body connector for connecting to a charger to charge a power source of the stylus. A separate functional end module is removable from the main body to expose the main body connector. The functional end module includes a functional component and a module connector that communicates with the main body via the main body connector. Various different functional end modules can be interchangeable to provide a variety of distinct features to the stylus.
