In the rephone pinout it labels the six pins on the right: gnd, int1, int2, vcc, SCL and SDA. Could int1, int2, SCL and SDA be used as GPIO?
yes the int1,int2 SCL and SDA can be used as GPIOs.
Please refer to the following schematic:
For more info about the module schematics you can find at resources of Xadow GSM+BLE
How could I use these pins in the arduino IDE? If I upload the blink sketch with pin 13 it doesn’t work.
check the topic I just posted. Access the GPIO Pins based on Different IDEs
Thanks! I’ve got int2, SDA and SCL working with the blink sketch. But int1 isn’t working for some reason. I tried the blink sketch with the pin number 0 and E1 but they both don’t work.
OK, here is an example which I just tested based on Arduino IDE for RePhone Kit. Make Sure your firmware is updated to the Arduino IDE for RePhone Version
[code]#define PIN_INT1 E2 //GPIO18
#define PIN_INT2 E1 //GPIO13
#define PIN_SCL 6 //GPIO43
#define PIN_SDA 7 //GPIO44
