Microcontroller › AVR › GSM interfacing with Atmega16
Right now I am trying a simple code of calling by GSM sim900 using atmega16
MY SETUP:Rx and Tx pins of atmega board are connected to Tx and Rx of my GSM modem and also to my uart bridge which i connect to my PC(done by splitting the Rx and Tx pins)-This was done so i could know whether my AT commands were given to modem or not
AT commands appeared as i wanted in terminal(X-CTU I have Used) that means they were actually given to modem also(since i splitte the wires).But no call was made.However when i myself entered the AT commands During the same process I was succesful
