Unable to use GSM and GPS Modules simultaneously
Posted: Mon Mar 19, 2012 8:57 pm
I am using the following chips:
PIC18f2550
GSM Module SIM900D at 9600 baudrate
GPS Module M-89 at 4800 baudrate
Problem is that, I can not combine both functions at the same time in flowcode software. If I use GSM module in my flowcode then I lose functionality of GPS ie the GPS flowcode module never responds, and vice versa. (I have used 2-1 mux to control their either gps/gsm input into single RS232 RX, and that hardware is working ok)
During compiling I got errors of tst variable used twice, but I renamed it in gsm component c file, and no more compiler errors. I have attached the flowcode file.
Any recommendations on how to use both of these functions (gps and gsm) at the same time. I can change the pic microcontroller chip if someone recommends that he had successfully used both these functions in some pic microcontroller.
