How determine antenna type in firmware?

Postby plajjd » Mon Jan 13, 2020 11:00 pm

I have a product that uses both ESP32-WROOM-32U (with U.FL antenna connector) and ESP32-WROOM-32D (With PCB antenna).

I would like to determine identify the module in software.

Is there a eFUSE bit or part number that I can access in software to tell the difference between the WROOM-32U and 32D?

Thanks!

Phil.
