In AT command which will be the 'ssid' and 'password'? And I am not getting the data to thingspeak does ssid and password will solve the problem? And do we need to use a external powe supply for ESP8266-01?
Did you use an external 3.3V to power the ESP8266-01 or you used the Arduino Uno board to power it?
