1. A method, comprising:
by operation of a wireless device configured to operate according to at least one wireless standard that includes primary advertising channels:
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; wherein
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.
