Hi Dear,
Thanks for your reply.

Password:guest
Device is GPRS activated and I have received the GPRS Info as follows:
IP 10.16.172.232

Please let me know how I can read data from GPRS activated finger print device through webserver using VB.NET
Thanks in Advance

I have x990 GPRS activated finger print device.
I want to access data stored in device [for e.g. in/out time of employees] using VB.NET.

What do you exactly mean by access this device through web server? Is the webserver built-in to the device? If so, does your your mobile internet service allow inbound HTML connections?

In any case, a link to a product datasheet, manufacture website, whatsoever, would be helpful.

Hi all,

Thanks to everyone, for sharing the valuable information, in this thread. You are all been very helpful, indeed.

My question, rather problem, is that I am using Wavecom Multiband 900E 1800 modem, for the same purpose. But in this thread, though very helpful, but it is primarily for SIMCOM modem. As we all know, the AT commands of these two modems differ much. Can I get same information, for data transferring between Wavecom Modem and Remote Server or is there any information available for the equivalent commands for SIMCOM & Wavecom. I am sure this would be beneficial for lot of people, who are using Wavecom modems.

Thanks to all, again, for this extremely useful thread. Best regards.

Re: gprs data transfer

Dear All
I go to send data over Gprs via Wavecom Fastrack M1306B modem.
I send at command by Hyper terminal but it show error.you think whats problem?

Code:

AT+CREG?
+CREG: 0,1
OK
AT+CGATT=1
OK
AT+CGDCONT=1,"IP","MCINET",,0,0    (///// [url]www.mci.ir[/url])

FvM · Mar 17, 2012

Any indications that the Wavecom modem supports the TCPIP specific commands you are trying here?. As far as I see are these SIMCOM specific commands. Wavecom's Open AT command set doesn't provide TCPIP commands, I think.

hi there...
im having a problem, im using arduino uno + sim900 gprs shield from seeedstudio
im trying to send data from arduino to my web server, which using php script to read the data that arduino sent
but the data still cannot be written to my database (im using mysql as database)

this is the command that i used for arduino using terminal v1.9b

Code:

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


>> AT+CGDCONT=1,"IP","telkomsel"	- 
<< OK



>>AT+CSTT="telkomsel","wap","wap123"
<< OK

>> AT+CIICR    
<< OK

>> AT+CIFSR	
<< 182.8.224.31	
<< OK

>> AT+CDNSCFG="167.205.44.3","167.205.30.5"
<< OK

>> AT+CIPSTATUS		
<< OK
<< STATE: IP STATUS

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


>> AT+CIPSTART="TCP","167.205.55.7","80"
<< OK
<< CONNECT OK		
>> AT+CIPSEND		
<< >			         
>> GET /sensor/indexx2.php?websensorco=7.8 HTTP/1.1

and also i,ve used ctrl+z to send the data and it replied with "send ok"

and this is the script that i use to recieve the data from arduino, and store the data to mysql

Code:

<?php
$outputCO=$_GET["websensorco"];


$con = mysql_connect("localhost","admin","admin");
 mysql_select_db("ichi", $con);
  $query = "INSERT INTO tabel5( tabelCO, tabelNO, tabelSO, Temp, date) VALUES ('$outputCO',  '$outputNO',  '$outputSO', '$outputTEMP', '$today')";
$result = mysql_query($query) or die("Anfrage fehlgeschlagen: " . mysql_error());
 mysql_close($con);
 ?>

please help me to solve this problem sir..
i really appreciate it..
thx

Re: gprs server

GSM Man said:

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.

First you need to open a PDP context.

Code:

>> 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@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]

i am doing project vehicle tracking using gps and gprs . i have used same commands using hyperterminal . however TCP connection to google is successful using IP address instead domain name . then after > FET/HTTP/1.1 Then modem becomes hang and no respone is obtained untill modem is restarted. please help me. what can i do?

As soon as i send AT+CIICR command it gives a message +PDP: DEACT. what should i do?? it shows something like this..

AT+CIICR
+PDP: DEACT

ERROR

rafati · Sep 19, 2012

hi abhiinav

i am sorry. your modem cant connect to BTS and data transmit with center to enable GPRS .
i suggest you to see your modems ability and connectors in circuit of modem board and then properties of sim card for GPRS.

Progressio · Oct 1, 2012

Does anybody know how to send a SOAP string via SIM900 to communicate with a ASP.net Website. Or does anybody have experience with POST HTTP Commands via SIM900?

Harborbreeze · Oct 6, 2012

Sorry, but I don't know what you want to say about this. It depends on the type of request you are marking.

How to make a PC side remote server with ip address to connect with simcom300

GSM man Thanks in advance.

rafati · Apr 21, 2013

amolypalshetkar

I think that:

- with hyper-terminal software you can connect to simcom300 and then with this connection can connect to another GSM modem.

- for remote server you must have static IP address to connect with other modem.

kango2020 · Feb 9, 2014

I've been following this tread with great interest, but unfortunately I was not able to give an answer to a question. Since in the system to upload to a server is to use the ftp protocol that here mè you can not use the fact that there is no manager to let through traffic on port 21. Using the HTTP protocol, and get command, we are inside the server ok but then how do I get my web space with my username and password that must serve to be able to edit the file? I do not think I have seen in a long trend way to do this. Or am I wrong?
