-Extended advertising may use multiple PHYs and spread payload across many packets. This allows for much larger payloads. In this case advertising is split across primary advertising on the advertising channels and secondary advertising using channels normally used for sending data to connected devices.

-Similarly, if supported by the controller, periodic advertising may be used to send changing data to many peers. Each peer needs to scan the advertisements on the primary channels and create a sync with a periodic advertisement it's interested in.
