I tried with arduino nano and I got this error: .

Hello, I don't speak English but I will tell you about an experience I had between Arduino Uno and ESP8266 ESP-01. I had the same error when trying to load a program and had the following solutions. -If you have an arduino uno in which you cannot remove the atmega CPU manually, you must connect the arduino uno reset to ground with that it will let you charge, also remember that to program in esp8266 esp-01 you need to connect the GPI0 to ground and the en(enable) to 3.3v -If you have a direct converter from esp8266 esp-01 to serial (usb), remember that the GPI0 has to have a bridge with ground to program, generally it is chosen to solder it with a button since these normally do not have an integrated one.
My esp8266 still show failed to connect to esp8266: timed out waiting for packet header. It still not solved after i unpin IO0 and pin again. Pls help me.
