In this Hardware Flow control, RTS and CTS will come into the picture. ... If you want the Arduino IDE to automatically reset the esp32/esp8266 then connect the DTR or RTS pin of the FTDI or UART to the "EN" pin of the esp32/esp8266. The FTDI/UART should momentarily pull the EN pin ...Once ESPHome has finished installing, we can create a new file called something like web_control.yaml using the wizard. esphome web_control.yaml wizard. In the first step we will choose a name for our device. You can call it whatever you like. Next we need to specify whether the device is an ESP32 or ESP8266.Jul 23, 2019 · IOT feito fácil”: Brincando com o ESP32 no Arduino IDE.
