I am using a CySmart BLE 4.2 dongle to detect and connect to my CVBT-42302802 module. I am using BTSpy.exe and ClientControl.exe with the appropriate trace messaging in my WICED application configured for WICED_ROUTE_DEBUG_TO_WICED_UART. When the CySmart dongle requests pairing, I get the following messages at the end of the pairing process.

What is command 0x204e? I can't seem to find any documentation on this command.

0x204e is the LE Set Privacy Mode Comand. You can find the command details in the Core_v5.0 vol2, Part E, 7.8.77.

Or you can also find it in the CyBluetool CyBluetool (Windows Installer)

Thank you for answering my question, Owen. So, what is reporting the Set Privacy Command as "Unknown"? Is it the BTSpy/ClientControl software or the CYW20719 module?

The BT Spy capture the HCI command between the host and the controller, then try to analyse it. The "Unknown" is caused by the BTSpy software.
