Unable to use GSM and GPS Modules simultaneously

[awaisnaz]

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.

Hello,

Since you posted a Flowcode v4 file im going to move your post into the Flowcode v4 section.

If you require access to the v4 forums then please follow the instructions here: http://www.matrixmultimedia.com/support ... f=29&t=602
