Being a newbie to Arduino, I'm trying to implement AT commands in the serial monitor, though in vain. After connecting the ESP8266 (01) module to an Arduino Uno, I tried to scan for the nearest network present [code link: https://github.com/esp8266/Arduino/blob/master/doc/esp8266wifi/scan-examples.md#simple-scan] and it worked perfectly.
But the moment I am trying to connect to send AT commands (even manually), it shows nothing. In addition,
if(esp8266.available())< both are giving false value.
What am I doing wrong?
