Hmm, I thought the question was about getting an ESP32 to output clock signal to substitute a broken clock crystal on another microcontroller. The code example referenced in the question is to generate 20MHz square wave at 50% duty on GPIO18.. Whereas isn't this answer is about detecting the 2.4 GHz WLAN WIFI output from the ESP32 transmit antenna?
