It to simple establish the GPRS connection and send / receive a block of data.

If it takes you ten mins then all the better.

hi,
use the GPRS modem TELIT GM862 GPRS
www.gm862.com
the GPRS attach is COMPLETLY achived by internal firmware.
you simply issue an AT+ like command, specifiing the
IP address, PORT number, packet type (UDP or TCP)
and then the modem connect itself to the internet word,
make the packet with data entered into the serial port,
and send the packet to the specified IP address...

few firmware line and the job is done ..
GREAT !!!

regards

Mauro

So here are the quetions so far.

1) I have WAP enabled on my SIM is it therefore GPRS enabled? or are all SIM's GPRS enabled (as long as the network is GPRS enabled)

2) My sim is a Orange SIM does this mean I should use "AT+CGDCONT = 1,"IP","Orange","0.0.0.0",0,0<cr>"?, If not how do I find out what APN to use.

3) Is using 0.0.0.0 basically asking for a IP address?

4) The AT#USERID returns ERROR, I send AT#USERID="Ben Hoelke" and get back ERROR

5) Same with AT#PASSW

6) Once connected is that connection always there even as I move between Cells and loose signal?

The example below is taken from the PDF for the GSM

AT+CGDCONT = 1,"IP","internet.gprs","0.0.0.0",0,0<cr>
AT#USERID="Ben Hoelke"<cr>
AT#PASSW="EASY GPRS"<cr> AT#SKTSET=0,80,"www.roundsolutions.com"<cr>
AT#SKTOP

Hi, I posted a message on the bulletin board run by the mobile phone unit that you are using, search that board for

re: GPRS Email in the UK ( Orange) example - 10.06.2003, 21:57:09

The bulletin board is at
http://www.modem-gsm.de/forum/

Basically I just use a PIC to drive the GPRS stack builtin to the mobile phone. I am only sending email and the response back to the PIC are bound to be short so I do not use handshake on the rs232 lines. It has not been a problem with the short emails that I send.

It was a days work to "port" from an existing CSD application, just meant removing a lot of the PIC code, previously I was using a firmware PPP module and using the phone as a 9600 baud modem.

In terms of ensuring the data got sent, there is sufficient handshake in the email protocol to ensure it reached the email server ok.... better would be a complete packet driven client/server ... maybe beter to use tftp and check a checksum... email me if you wish IJ.McCrum <AT> ulster.ac.uk
