ESP8266 + local server = 400 Bad Request
Posted: Mon Mar 06, 2017 6:04 amI'm using ESP8266 with actual firmware ESP8266_NONOS_SDK_V2.0.0_16_08_10.
I do database query to PHP + MySQL using at commands.
On Internet network
... ESP8266 works fine for example: zzzzzzz.zzzzzzzzz.zz/dodaj_rek.php?n=129&u=1488723073&d=-51&s=203
AT+CWMODE_CUR=3
AT+CIPSTART="TCP","zzzzzzz.zzzzzzzzz.zz",80
AT+CIPSEND=89
GET dodaj_rek.php?n=129&u=1488723073&d=-51&s=203 HTTP/1.1\r\nHost: zzzzzzz.zzzzzzzzz.zz\r\n\r\n
server answer:
+IPD,189:HTTP/1.1 200 OK
Date: Mon, 06 Mar 2017 02:29:39 GMT
Server: Apache/2
X-Powered-By: PHP/5.3.29
Vary: User-Agent
Content-Length: 11
Content-Type: text/html; charset=UTF-8
CLOSED
and new rekord in database has been added coorectly.
Server in local network
I installed actual version of Apache, PHP and MySQL on computer with Win10(64-bit) and IP 192.168.1.51 listenning on port 80.
SSL is not enabled.
When I'm using such url:
192.168.1.51/dodaj_rek.php?n=129&u=1488723073&d=-51&s=203
in web browser of any machine (computer, smartfon, tablet) in my local network via WiFi or LAN, every thing works fine.
Problem arises when i'm trying do the same using ESP8266.
AT+CWMODE_CUR=3
AT+CIPSTART="TCP","192.168.1.51",80

AT+CIPSTART responds correctly connecting to the server
AT+CIPOSEND responds correctly showing prompt: >
After sending GET responds:
Recv 81 bytes
SEND OK
but server generates error: 400 Bad Request

I attach configuration files of PHP and Apache.
I spent a lot of time and I can not find the reason
