GPRS connection steps

**Iphone** · 29-Mar-2007, 12:41 AM

After reading many posts about GPRS, I don't find the answer I am looking for.

I know that for making a GPRS conection I need the AT commands, OK.
But I don't have any idea how to make the PPP link,

Can someone explain what steps I can follow to complete the connection operation ?
and if is posible what I have to use (a program developed completely from me, the TAPI, ???),
because I am completely lost.

AT+CGATT=1<cr>

AT+CGDCONT=1, "IP", <APN>, "", 0, 0<cr>

AT+CGACT=1,1<cr> (but you don´t need this one...)

ATD*99***1# (for MC35T, it might be different to you, say ATD*99#)

After this, get a CONNECT string and do the LCP, PAP/CHAP and IPCP negotiations.
