I only have 1 Serial port. GSM shield uses pin number 2 and 3.
So you only need to set the baud rate once for the BLE (115200) and once for the GSM (9600)
QuoteSo you only need to set the baud rate once for the BLE (115200) and once for the GSM (9600)So, how do i do that ya especially for the GSM shield?
I see that PINNUMBER is defined as an empty "" -> I think a number should be in probably 2 or 3#define PINNUMBER ""
PINNUMBER = ""; //PIN on the SIM card if there is. Optional.
The GSM is already using a SoftwareSerial internally on Pin number 2 and 3. Otherwise, It won't be able to send the SMS right?
That's what I don't understand.If I set the Serial to 115200, I cannot configure or make the GSM work ~ T_T
