The diversity scheme is a proprietary algorithm which is not described in a public document. I can say that the scheme selects the "best" antenna to use based on a range of radio measurements and statistics which include parameters such as received signal strength, retries and packet errors but cannot share the exact scheme.
Thanks for the reply.
What is the default settings for antenna diversity. When I run the WICED SDK, I do not see any call to wwd_wifi_select_antenna() in the initialization flow.
Thanks & Regards,

The antenna control is handled by the radio firmware. We do include commands for forcing which antenna is to be used, such as wwd_wifi_select_antenna(), but these are typically only used when there is only a single antenna on the design. The second use case for forcing the antenna selection is for rf testing when you need to connect to a known rf port (or antenna port) for testing eg using console or mfg_test app.
In all other situations we advise leaving the diversity control as auto.
