I have a code to fetch a http response from a server using HTTPCLIENT and UIPETHERNET libraries and at the same time i have a code for sending an sms to a user who calls the gsm mosule with the help of GSMSHIELD library(for sim900).
when i do run these two codes seperately, i am getting proper outputs and it is working fine. But when i combine it to one..nothing is shown in serial monitor...its not working...
i need to fetch a database and get the stored data and send it to a user as sms once he makes a call.
