SIM600 and Sending Data over TCP/IP with GPRS?

[BasePointer]

send data via gprs

Hi,

Now I'm working on SIM600 EVB kit and trying to send data over TCP/IP with GPRS.

I have some question with it. I can successfully attach to GPRS, but can't send any data via TCP/IP.

My GSM provider needs
APN: internet
User: gprs
Pass: gprs

I want to connect/send/receive my server has static IP: 78.XXX.XXX.108, port: 2222 with TCP. I can easily connect to my server with Motorola G24.

Please help me for required AT Commands and sequence.

AFTER POWER-UP the SIM600 EVB KIT:
------------------------------------------
+CFUN: 1
+CPIN: SIM PIN
------------------------------------------
at+cpin="1045"
+CPIN: READY
OK
------------------------------------------
at+cmee=2
OK
------------------------------------------
at+csq
+CSQ: 19,0
OK
------------------------------------------
at+cgdcont=1,"IP","internet"

------------------------------------------
at+cgatt=1
OK
------------------------------------------
at+creg=1
OK
------------------------------------------
at+cgact=1,1
OK
------------------------------------------
at+cstt="internet","gprs","gprs" -> why ?

at+ciicr

at+cifsr

here "AIRTELGPRS.COM" is the APN(access point name) because i am using Airtel sim card.you can check it in your mobile.

If error occurs use AT+cipshut and then use at+cipstart.

Hi,

As I learn, Sim600 doesn't support TCP/IP command set. So we switched SIM700 and it works perfect.

hi guys.. if AIRTELGPRS.COM is the access point how can we configure or program a general embedded device with this module which can use any other acess point like that of idea's or vodaphone's or mtnl's

Thanks
