Bluetooth low energy Packet Error Rate Channels

  • For Classic Bluetooth: Each channel contains a bar that displays the number of packets with no errors in green, packets with Header Errors in red, packets with Payload or CRC errors in dark red, and Retransmitted packets in yellow.
  • The red number at the top of the channel shows the percentage of Header Error and Payload/CRC Errors in relationship to the total number of packets in the channel.
  • The light blue number at the top of each channel shows the megahertz (MHz) for the channel if the option is chosen in the Additional Statistics section.
  • When you select a channel, detailed information for that channel is displayed in the expanded chart on the upper right.
  • The channels change dynamically as the Viewport is moved or new data appears within the Viewport.
  • The Channel Not Available symbol is displayed if the channel is not available in the most recent channel map that is in or before the last selected packet, even if that channel map comes before the first selected packet. Bluetooth Adaptive Frequency Hopping processes will block channels determined to be unreliable. These channels are not available because the Bluetooth devices have decided not to use them.
