I am using Arduino Nano to interface with the GPS module and GSM module. For the serial communication between the two, I was using the SoftwareSerial library. But the issue with the interfacing is that both work fine when I am using it separately but it does not Arduino does not response to any one of them when I am using both at a time. Can anybody tell me what’s the problem is?
Actually, I want to know the limitation on the number of Serial Communication, we can have.
