This section describes the calls, events, signals, and return actions of the Radio Timeslot API.
A Timeslot session is opened and closed using API calls. Within a session, there is an API call to request timeslots. For communication back to the application the feature will generate events, which are handled by the normal application event handler, and signals, which must be handled by a callback function (the signal handler) provided by the application. The signal handler can also return actions to the SoftDevice. Within a timeslot, only the signal handler is used.
