I am using SIm900A module to get data using cipsend command.
I don't receiving anything agter GET command. below is code.
baud is 9600.
-> Input to SIM900
<- output from SIM900
2. I have SIM900A connected to PC via RS232 cable. Using realterm to send commands. (also tried hyperterminal)
3. I have put sim in mobile & checked internet is working on it.
