Use HX711, its low cost and works great, you get direct digital data without messing with analog amplifiers.

Good to see your results,
I then ended up using CP2102 in my production run instead of microchip MCP2200.
Good that i was able to caught such issue in my development boards, so i was able to revise my design.
Re: How i can work with header file keil only without library cmsis or other?
see https://www.keil.com/gsg
its for MDK5 getting started guide.
you dont have to use any library except device files.
How about disabling interrupt when reading and enabling it again?
disable_interrupts(the interrupt that writes to global);
temp=myglobalvar;
enable_interrupts(the interrupt that writes to global);
you need to understand GPS signals are not strong as GSM.
GPS usually was made to work on open sky and not indoor buildings.
If you really need to make indoor then consider using active antenna with good gain.
lock has nothing to do with license. lock means the file is read only or located where it is shared by all system.
my project looks like below, see the shared file is locked and the other files created on the project folder path is not locked.
So i always use int8 or int16 or int32 as declaration so avoid such problems.
and i use make8, make16 and make32 functions to convert low bit variables to high bit values.
This is what CSS compiler says about variable declaration.
You are missing the enter key code \n or 0x13 after sending AT command.
My code looks like below, instead of writing own puts, its better to use built in printf functions.

I was in similar situation some time ago.
