Hi fiends ,
I have made GSM modul with SIM900d and PIC16F870 .
I make voice call and it work only if the gsm number is in code .
But i want SIM900 to take number from sim card . I have write number in sim phone book in first position.
For this i send via UART AT command :
AT+CPBS="SM"
ATD>SM1
And this not work ...
Could you please help me with code and commands .
My next question how i can make inspection when i have incoming voice call
if the number is in sim card - to switch relay
Regards !
