Hi all,I try to do a communication with the esp8266 and Arduino nano since few days, but nothing happens. I've tested many sketches, solution... I've used uart (0,1) from Arduino or SoftwareSerial on multiple I/O but not working.I also use external voltage ... When I send AT command directly in the serial monitor It work fine! So why when I send AT command with the Arduino, the esp8266 doesn't send a response?I'm total Lost...
