cipsend carriage return

Here's the commands you need to send. In the example below '>>' indicates data you send to the module, while'<<' indicates data returned from the module. This example is for connecting through the AT&T/Cingular network. You'll need to get the APN, user name and password for the network you are using. Also, you'll need to add your data to the request.

First you need to open a PDP context. 

>> AT+CGATT=1   - Attach to GPRS Service 
<< OK 

>> AT+CGDCONT=1,"IP","wap.cingular"   - Define PDP Context (cid, PDP type, APN) 
<< OK 

>> AT+CDNSCFG="208.67.222.222","208.67.220.220" - Configure Domain Name Server (primary DNS, secondary DNS) 
<< OK 

>> AT+CSTT="wap.cingular","wap(at)cingulargprs.com","cingular1" - Start Task & set APN, User ID, and password 
<< OK 

>> AT+CIICR     - Bring up wireless connection with GPRS - THIS MAY TAKE A WHILE 
<< OK 

>> AT+CIFSR      - Get Local IP address 
<< 10.190.245.172   - returns IP address assigned to your module 
<< OK 

>> AT+CIPSTATUS      - Get Connection Status 
<< OK 
<< STATE: IP STATUS   - returns status of connection, needs to be 'IP STATUS' before you can connect to a server

After you have context, you need to make a connection to the server and then send your data.

>> AT+CIPHEAD=1      - Tells module to add an 'IP Header' to receive data 
<< OK 

>> AT+CDNSORIP=1   - Indicates whether connection request will be IP address (0), or domain name (1) 
<< OK 

>> AT+CIPSTART="TCP","www.google.com","80" - Start up TCP connection (mode, IP address/name, port) 
<< OK 
<< CONNECT OK      - Indicates you've connected to the server - IT MAKE TAKE A WHILE FOR THIS TO BE RETURNED 

>> AT+CIPSEND      - Issue Send Command 
<< >                   - wait for module to return'>' to indicate it's ready to receive data 
>> GET / HTTP/1.1   - Send data - this example is an HTTP request for the default page 
>> Host: [url]www.google.com[/url] 
>> Connection: Keep-Alive 
>> Accept: */* 
>> Accept-Language: en-us 
>> 
<< data from server returned - Server will return data here

[/code]

simcom error 517

In my example, the APN, User ID and Password that I show are for the AT&T/Cingular network. You have to obtain these values for Your Service Provider and substitute them for the values I gave you.

invalid data when response sim508

You have to get them from the company that provides your cell phone service. These are associated with the phone network your GSM modem is connecting to - nothing to do with the Internet domain.

why i can send data with opening url via my mobile ??
my cell card work via <nokia n73> and send my data to web site but not work with gsm sim300c??

Because you phone was provisioned by your cell company to have that information stored in it.

please more explaine to me
and please explaine to me about Configure Domain Name Server (primary DNS, secondary DNS)
how to obtain two value primary DNS and secondary DNS ???
are these my destination ip address

When you make a request for a domain name (i.e google.com), a DNS server converts that URL into an IP address. When you set the DNS servers using the "CDNSCFG" command you are indicating which DNS servers you want to use. It doesn't much matter what DNS servers you use. A lot of people use the "Open DNS" servers that are at; 208.67.222.222 and 208.67.220.220.

[GSM Man]

cipstart domain

After you receive the "connect" status send the following:

AT+CIPSEND

Then wait for module to return'>' to indicate it's ready to receive data and send the following:

GET /default.aspx?s1=[1*1*1*1*1*1*1*1*1*1*] HTTP/1.1
Accept: */*
Accept-Language: en -us
Host: **broken link removed**

^z
[/quote]
Each line of data you send must have carriage return/line feed after it. Also, you must have one blank line after your data - it indicates the end-of-header. Finally, you need to send the '^z' (that's a control-Z) to the module to indicate the end of your data.

You should get a response from the module "SEND OK", and then the data from the server.

sim300c web based

When I try it from my system I get the following:

+IPD260:HTTP/1.0 302 Found
Location: **broken link removed**
Content-type: text/html
Connection: close
Date: Mon, 13 Jul 2009 16:49:02 GMT

CLOSED

The '302' response indicates that the "The requested resource resides temporarily under a different URI". Are you using a virtual host? I would check the host settings.

sim300c

Try adding the line "Connection: Keep-Alive" to the HTTP Header. This will tell the server to keepyour connection open.

Re: sim300c

HELLO MY FRIEND
i try to adding the line "Connection: Keep-Alive" as below:
AT+CIPSTART="TCP","www.gps.golzarci.com","80"

Host: www.gps.golzarci.com
Connection: Keep-Alive
Accept: */*
