I use arduino mega 2560 and esp8266 to output data to PHP by AT command.But nothing happened. Here is the instruction
input: AT+CIPSTART="TCP","waterheat.byethost9.com",80
output: CONNECT
OK
input: AT+CIPSEND=27
output: OK
input: GET /Insert.php?login=eee
output: Recv 27 bytes
SEND OK
CLOSED
No return value, PHP is not started, if I directly enter the URL in Google
input: waterheat.byethost9.com/Insert.php?login=eee
output: eee
Where is the problem?
Thanks in advance.
