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:

+WIND:61:Incoming Socket Client:192.168.1.126<CR><LF>

+WIND:60:Now in Data Mode<CR><LF>

GET / HTTP/1.0<CR><LF>

Connection: close<CR><LF>

+WIND:59:Back to Command Mode<CR><LF>

+WIND:62:Socket Client Gone:192.168.1.126<CR><LF>

Module 2 output:

Is this what you are trying to do?

I'm trying to do the same thing yes. I do receive something but the sentences are all mixed up...

Thanks for the quick answer again 🙂
