In addition, please write meaningful comments into the sketches. Some of the implementation details are really not explained.
Which pins are available to use for other purposes when using both GPRS and GPS functions? I would like to drive an I2C oled display and also a stepper motor. Is that possible?
Hello @kaandemirtas , AFAIK you should not use pins 5, 6, and 9, because they're used for A9G power management. However, if you must stick with these hobbyist boards, I would recommend the Maduino Zero SIM808, just because the SIM808 has far better documentation than the Chinese-only A9G.
Best regards
int pon=9; int poff=6; int lowp=5;
Do you mean that i can't use D9,D6, and D5 for other purposes?
