I am trying to make a envoirment reporting system using AT89S52 microcontroller and Sony Ericsson T68i Mobile Phone as modem. I was successful in submitting envoirment data using SMS through AT commands. Now I want to submit my variables to the webserver using GPRS. Do I have to implement PPP, IP and application layers in my microcontroller? Are there any prebuilt examples available? -- Regards, Irfan
Your phone does support GPRS, does it? If so, does it already have a TCP/IP stack? http://www.keil.com/tcpip/ http://www.sics.se/~adam/uip/ http://www.8052.com/tcpip/ http://www.8052.com/forum/read.phtml?id=87784 http://www.google.com http://www.altavista.com
Yes it does and i have successfully established the connection using serial port of my PC connected to the phone. i used pppd by samba http://ppp.samba.org its working perfectly alright using pppd on linux. now I want to ask is there any equivalant of pppd for 8051 microcontroller available? and how will I implement the higher level layers like application and ip do i still need tcp?
