Thanks for you answer.So I prefer to use deep switches. If I well understand the next step is to have AT commands response but I don't. What may I precisely have to do? Do I need to reflash the ESP? What are next steps?
I don't understand, they said to upload a sketch at the bottom of this page:https://robotdyn.com/uno-wifi-r3-atmega328p-esp8266-32mb-flash-usb-ttl-ch340g-micro-usb.htmlWhat I did. AT commands are not responding and the led of ESP is well blinking.load 0x4010f000, len 1384, room 16 tail 8chksum 0x2dcsum 0x2dvbb28d4a3~ldAT+CIPMUX=1AT+CIPSERVER=1,5000AT+CIPSTO=3600Are AT commands so importants for esp to Arduino communication or I can manage it by another way? if Yes, how can I do?
