A method can include monitoring at least one non-primary advertising channel for packets; determining if any of the packets received during a same periodic advertising interval of a periodic advertising link include synchronization data; in response to acquiring a packet with synchronization data, extracting synchronization data from the packet with synchronization data; and synchronizing to the periodic advertising link with the synchronization data to determine timing for at least one download window in each periodic advertising interval. The periodic advertising interval includes a plurality of periodic sub-intervals and the at least one download window corresponds to at least one of the sub-intervals. Corresponding devices and systems are also disclosed.

Wireless methods, devices and systems for rapid synchronization with periodic broadcast link

Implementations disclosed describe techniques and systems to facilitate efficient operations of wireless networks organized in a topology of communicating nodes. Techniques include cascade synchronization of various nodes of the network by generating and maintaining a common time using times associated with ordered communications between nodes. The common time maintained by the network allows performance of synchronous action for precise industrial, medical, and testing applications. The described techniques and systems further include management of communication windows between different nodes in a way that facilitates fast and efficient propagation of data collected by the network from multiple source nodes to one or more destination nodes. The techniques further include efficient assignment and flexible management of communication frequencies (channels) to various nodes of the network to reduce interference and noise by assigning different communication frequencies to the nodes that utilize concurrent communications windows.

Data flow management in wireless networks

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.

Device synchronization and connection management in wireless networks

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.
