This project is working!
I can read the ANALOG and PRINT the correct values, but, when i do the provisioning to SSID/PASS, the ANALOG is always reading 0
Is that a bug ? Some tip ?
So if you are trying to use any of the pins from ADC channel 2 starting wifi blocks their usage as that channel is completely consumed for use by the WiFi system.
This is just cut from the linked above doc page.
Unavailable ADC2 During Wi-Fi Connection
The ESP-IDF SDK (and possibly the ESP32 hardware) has a limitation where a Wi-Fi connection interferes with the device’s ability to read data from an ADC pin reading from ADC channel 2.
The I/O pins affected by this include the following:
IO27 IO26 IO25 IO15 IO14 IO13 IO12 IO4 IO2 IO0
Thank so much!
I had tried the IO4 too, and had got the same problem!
Thank you! I will test on others
Its working now!
Thanks a lot
