After all that, i have the simplest question.

Why after all these years, PBP havent improve itself with a newer and more competitive version? Then Everyone could buy the compiler with no thought.

Because as far as i see C is not only higher level language, but doesnt need asm.

Now i'm stack at this stage with the GPS project. Not that the code i have done is efficient or a super smart, but i thought i could send those GPS info, easier from one side to the other by using those modules. I thought that it would be a setup for TX -RX and then using only few command to send GPS data.

I think that i need to start learning C from the beginning.

Richard, thanks once again for all of your time and help.
