Sorry, I don't know anything about Hercules.

You could write some testing software to simulate the GPS to use with the program for testing to look for some first level bugs.
Have you communicated with the GPS with any software?

How can I test it? Do you have code to simulate the GPS?

I would test the receive program with special testing software that simulated the GPS to see if it would send and receive messages as expected.
I know nothing about hercules.

If that is an error message, you need to copy the FULL text and paste it here.

Do you have a program for testing in place of the GPS device?

Can you explain what the problem is?

How long do you want the program to wait before it decides that it is not going to receive a message?
