# Wizfi250: server web?

## Question

Asked by stephaneroque on 2016-11-21 in Wireless.

hi.

i have a problem with the AT command: AT+SSEND

[url][http://wizwiki.net/wiki/doku.php?id=products:wizfi250:wizfi250pg:start#at_ssend\[/url\]](http://wizwiki.net/wiki/doku.php?id=products:wizfi250:wizfi250pg:start#at_ssend%5B/url%5D)

I try this command:
AT+SSEND=0,146

And this command:
AT+SSEND=1,172.16.2.17,5000,146,50000

The answer is allways:
[ERROR: INVALID INPUT]

What’s the problem?
Thanks for your answer.

Hi,

There is condition to perform “SSEND” command.
First, UART DATA must be entered in 3 seconds.
Also, Total length of the data want to send, must be input within 10s + (Total Length)ms.
If both of the above conditions are not met, Timeout occurs.

Thanks.

thanks for your answer, but i don’t understand when the timer start.

I think, the timer start after this command AT+SSEND and not before.

Example:
<https://wizdaniel.wordpress.com/2015/08/17/wizfi250_ssl_connection/>

[code]AT+SSEND=0,146
[0,146]

> > > > SEND DATA
> > > > HTTP/1.1 200 OK
> > > > Server: nginx
> > > > Content-Type: text/html; charset=utf-8

[Google](http://www.google.com)

[OK][/code]

The answer for this example is [0,146] and not [ERROR: INVALID INPUT]
I have 1s beetween AT+SCON=O,TSN,5000,0 and AT+SSEND=0,146
i try to insert less.

Yes, the timer start just after entered AT+SSEND command.

Thanks.
