About "ESP8266 - WiFi Remote Configuration" Everything is working I can send command from my PC to serial port of ESP8266.
But I can't Read the sensor that is connected to my arduino board that sends a command to the serial port of the ESP8266 to my PC. Someone tell me how to do it. I'm using this code for the first time.
I repeat it works for me, I send the temperature every second with arduino through the TX uart.
With esp8266 RX I receive the temperature and then print it on the web page.
I don't know why it doesn't work for you.
If you want I am attaching my example, just to look at the code.
