Hello Friends,
I am working on a project in which, my 8051 based instrument will communicate to a PC side software over GPRS network. In the existing system, my instrument reads its inputs and sends the data to the PC side s/w [which i have written in VB] through RS232 link. Now we want to replace the RS232 link with a GPRS network. I have got a GPRS modem [sim300]. I am implementing the necessary AT+commands to interface the modem. But the question is, what I have to do with the PC side s/w? Do i need to have a server/domain on the internet? or my PC side s/w can be modified to act as a server? How to get public IP adress for my s/w? Is it MUST to implement FTP protocol on the instrument side, or some different simpler protocol [like Modbus serial communication ] can be implemented?? Lots of questions! Please suggest me a way.. Thanks Did your's like this: 8051+SIM300++++GSM network------PSTN---USB/Serial modem---PC/server. What kind of OS for PC/server? Suppose that like above. Just needed make the modem(USB/serial) worked to answer the incomming dial. There's at manual to activated the autoanswer. and install at OS the server program(PPPd or Slipd,FTPd,HTTPd,etc). NO need connection to Internet for sent data to PC/server. Making IP like 192.168.X.X or 10.X.X.X Thank's Jeckson Ben |
