Advertiser timing

Advertiser is started as early as possible, after a random delay in the range of 3 - 13 ms, asynchronously to any other role timing-events. If no roles are running, advertiser timing-events are able to start and run without any collision.

When other role timing-events are running in addition, the advertiser role timing-event may collide with those. The following figure shows a scenario of Advertiser colliding with Peripheral (P).

A directed high duty cycle advertiser is different compared to other advertiser types because it is not periodic. The scheduling of the single timing-event required by a directed advertiser is done in the same way as other advertiser type timing-events. A directed high duty cycle advertiser timing-event is also started as early as possible, and its priority (refer to Scheduling priorities) is raised if it is blocked by other role timing-events multiple times.
