Topic: HAS THE PIN CONFIGURATION FOR SIM7000C CHANGED SINCE 2018? (Read 12221 times) previous topic - next topic


I have recently purchased a sim7000C from DF Robot. thecode by Timothy Woo is referring to the following pins:

#define FONA_TX 10 // Microcontroller TX
#define FONA_RX 11 // Microcontroller RX

but the board has TX/RX at pins 1/0 respectively and there is a toggle switch on the board that allows you to use pins 7/8 as RX/TX also. Shouldnt the above lines then be:

#define FONA_TX 8 // Microcontroller TX - GAURANG
#define FONA_RX 7 // Microcontroller RX - GAURANG

Also then what should these lines be?

#define FONA_PWRKEY 6
#define FONA_RST 7

I am thoroughly and utterly confused. Someone help please.
