The "Failed to create heat map for MAC: xx:xx:xx:xx:xx:xx Reason: Failed to find any APs in the database for a RSSI list" error message appears in WCS version 4.0 with Location Server version 2.1

Core Issue

This error message appears in planning mode and the heat maps do not work properly.

This issue is due to Cisco bug ID CSCse83815.

Resolution

As a  workaround for this problem, complete these steps:

  1. Choose Monitor > Maps and choose the floor where the access point (AP) heat maps do not appear.

  2. Choose position aps from the drop-down menu on the far right.

  3. Choose the AP where no heat map works.

  4. On the left side, choose Other for the Antenna Type and Save.

  5. Return to the Antenna Type, choose the original antenna, and Save again.

  6. The heat map for the AP now works.

In order to resolve this issue, upgrade the Wireless Control System (WCS) to firmware version 4.0.81.0 or the latest version, which is available at Cisco Downloads.
