Hi,
I am working on GSM/GPRS modem. I want to connect my modem to the web server using any GSM/GPRS enabled modem and a Arduino Uno/nano board. What i want is: i should be able to send the data to a web server and as well as i should be able read the data from the server from the same modem. Do we need to switch the modem between client mode and server mode every time while receiving and sending data? because i have seen some example code in Arduino IDE which has separate code for sending and receiving data from server.
Thank You.
