low energy Timeline Visual Elements

The low energy Timeline consists of the following visual elements:

• Time Markers - Time markers indicated by vertical blue lines are shown at 1.25 ms intervals. The markers are provided to help visualize the timescale and are also useful when using dual-mode chips  that do BR/EDR and LE at the same time.  Time markers snap to the beginning of the first data packet by default, but they can be snapped to the beginning or end of any packet by right-clicking on a packet and selecting Align Time Marker to Beginning of Packet or Align Time Marker to End of Packet. All other markers will shift relative to that new reference point.

  

  Timeline Markers Shown Snapped to End of Packet

• Timestamp - The beginning and ending timestamp for each segment is displayed beneath each segment.  When showing multiple segments the beginning timestamp is the same as the ending timestamp of the previous segment.

  In addition to the timestamps the segment information bar shows the zoom value in the center of the bar.

  Note: The raw timestamp value is the number of 100-nanosecond intervals since the beginning of January 1, 1601. This is standard Windows time.

• Packet Info Line - The packet info line appears just above the timeline and displays information for the currently selected packet.
