Custom socket usage

Hi,

I'm trying to use custom socket with two SPWF01SA, but I'm having some troubles:

-I can't find the documentation, to know how it works exactly

-I have a creepy behavior once I try to send data from server to client

I have disabled the standard HTTP socket on port 80 (TCP) and I have set up my own on the same port. Then the server waits the WIND:61 indication (incoming socket) to send the following text through the UART:

 ''HTTP/1.1 200 OK  - HTTP version as in GET\r\n''

''Content-type: text/html\r\n''

''Content-length:15\r\n''

''\r\n''

''<html>_|_<html>''

I use the other  SPWF01SA as a client and after a wi-fi association I use ''AT+S.HTTPGET=172.20.146.1,/index.html\r'' expecting the previous text, but instead I receive:

''t-type: text/html

ersion as in GET

Content-length:15

html

ersion as in GET

ntent-length:15

html

ersion as in GET

<html>_|_<html>15

html

ersion as in GET

[1A][1A][1A]''

Am I doing something wrong? And where can I find the documentation on sockets?

Regards,

Hector

    Hi,

    I did the same attempt, but I have good results.

    Module 1 - server:

    - turn off web server - at+s.httpd=0

    - turn on socket server - at+s.sockd=80

    Module 2 - client:

     - request resource - at+s.httpget=_ip_,_res_

    Module 1 output:

    Is this what you are trying to do?
