The Radio Notification is a configurable feature that enables ACTIVE and INACTIVE (nACTIVE)
signals from the SoftDevice to the application notifying it when the radio is in use.
Radio Notification signals
Radio notification signals are used to inform the application about radio activity.
Radio Notification on connection events as a Central
This section clarifies the functionality of the Radio Notification feature when the SoftDevice operates as a Bluetooth®
Low Energy Central. The behavior of the notification signals is shown under various combinations of active central links and scanning events.
Radio Notification with concurrent peripheral and central connection events
The Peripheral link events are arbitrarily scheduled with respect to each other and to the Central links. Therefore, if one link event ends too close to the start of a peripheral event, the notification signal before the peripheral connection event might not be available to the application.
