First, make sure you can connect to a remote server on the internet using HTTP on port 80. Your service provider may be blocking ports other than 80.

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.

Code:

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.

Code:

>> 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

If you get this working you can try connecting via the FTP Port. The problem with FTP'ing is that you need two simulataneous connections - one for commnds and one for the data transfer.

thanks for replay
I think I m sur.
heir is my providers informations:
SFR (name of provider - from France)

Wap GSM

* Profil name : WAP SFR GSM
* connection number : +33613000010
* principal IP / annexe : 195.115.025.129
* Principal Port / annexe : 9201
* USER : "none" //no user
* PASS : "none" //no pass
* homepage : **broken link removed**

Wap GPRS

* Profil name : WAP SFR GPRS
* accès Point: wapsfr
* USER : "none" //no user
* PASS : "none" //no pass
* principal IP Adresse : 195.115.025.129
* port number : 9201
* homepage : **broken link removed**

MMS SFR

* Profil name : MMS SFR GPRS
* accès Point : mmssfr
* USER :"none" // no user
* PASS : "none" //no pass
* Passerelle (gatway !!) : 010.151.000.001
* Message Serveur : **broken link removed**

Web SFR

* name: WEB SFR GPRS
* accès Point : websfr
* USER : "none" // no user
* pass : "none" //no pass
* network Protocole used : TCP/IP
* IP Adress : Attribuée par le serveur
* DNS primary : 172.20.2.10
* DNS secondar : 194.6.128.4

So all is heir: if I want to connect to google.com what the argument of at commands chould I set:

note when I try cipstart I got:

Code:

at+cipstart="tcp","207.210.244.11","9201"
OK
CONNECT FAIL
STATE: IP IND
+PDP: DEACT

What about IP IND ???? meaning?
thanks a lot for your time

Try connecting to Google using the following CIPSTART command:

Code:

 AT+CIPSTART="TCP","www.google.com","80" - TCP connection to Google.com on Port 80

Make sure that you set the IP address to use the Domain name:

Code:

AT+CDNSORIP=1

The Port value in the CIPSTART command is the port on the server that you want to connect to - 9201 is a port related to your serv ice provider.

You're trying to connect to the Google web server on its port 9201. That server doesn't have a open port at 9201. You MUST CONNECT ON PORT 80

Change your command to:

Code:

at+cipstart="TCP","www.google.fr","80"

Dear litham: you forgot to ask for SIM300 local ip, this step is madatory. Take a look to this example.

// Set APN
AT+CSTT="APN","USERNAME","PASWORD"<CR>

// Bring Up Wireless Connection
AT+CIICR<CR>

// Get Local Ip (Mandatory Step, Check SIM300 AT Commands)
AT+CIFSR<CR>

// Connect with domain name server
AT+CDNSORIP=1<CR>

// Configure Domain Name Server
AT+CDNSCFG="PRIMARY_DNS","SECONDARY_DNS"<CR>

// Connect to Server Example
AT+CIPSTART="TCP","www.google.cl","80"<CR>

Good Luck

Sorry, but this isn't true - there is no requirement that you query the local IP address! This is simply an 'infomrational' command - provides information only.

sim300c pdp: deact

Hi all
thanks , but the problème stiil
pepin82, AT+CIICR, returns ERROR .

+CGDCONT: 4,"IP","websfr","",0,0

OK
at+cgact=1,4
NO CARRIER
OK
//--------------------

tnx

If you follow the sequence I gave you earlier, after the 'AT+CIICR ' comnmand is issued you should receive a reply from the module of 'OK'. If you don't, then the network is not recognizing you. If your plan supports GPRS, then the most likely cause is that the APN, User or password is not correct.

Hi all,
I call my provider s and tell theme what was wrong, annnnd, in my first call they gave me a wrong APN. so finally I get the exact one. and it works fine I get a CONNECT OK.

BUT, no it's Okey :lol:
