The documentation says:
"To use system_adc_read_fast, Wi-Fi has to be disabled."

What are the expected adverse effects from having WiFi on, and running system_adc_read_fast? Does the WiFi TX add a lot of noise to the rails, which can contribute to ADC noise? Or is there another reason this is not recommended? The SDK seems to allow this, and returns satisfactory results.
