This section gives an overview of the power profile of the scanning event implemented in the SoftDevice. Scanning event shows the current profile for a scan event. When the SoftDevice receives a packet, it transitions from stage E to stage F. For each advertising packet the SoftDevice receives, the sequence D-F is added to the current profile. For each secondary channel advertising packet the scanner receives, the sequence A-F is added to the current profile.
