Abstract
A local device broadcasts a first advertisement in a first wireless network via a first wireless interface, where the first advertisement includes one or more service identifiers (IDs) identifying one or more services being advertised and an availability schedule of the local device in the first wireless network. The local device broadcasts a second advertisement in a second wireless network via a second wireless interface. The local device scans in the first wireless network during an availability window of the availability schedule for a response to the first advertisement, where the broadcast of the second advertisement is disabled during the availability window.
