#89145 Hello, I am consulting something strange that is happening to me in case it has happened to someone and can help me. I have an application with ESP8266 ESP01-S working correctly. I bought new ones and with these there is no way to make it work. The only strange thing I find: IO0 is configured as INPUT_PULLDOWN, so all the voltage measured on that pin is 2Volts, not 3V3 despite adding another external pull-up. If anyone can help me I am very grateful
