To link to libbluetooth.a library I have to add ": " to option.
Why?

Invoking: GCC C++ Linker
g++ -L/usr/lib/x86_64-linux-gnu -v -o "TEST_BT" ./src/TEST_BT.o -l:libbluetooth.a

Learn the linker options
https://gcc.gnu.org/onlinedocs/gcc-11.2.0/gcc/Link-Options.html
scroll down to "-llibrary"

From the man page for ld:

-l namespec
If namespec is of the form :filename, ld will search the library path for a file called 
filename, otherwise   it will search the library path for a file called libnamespec.a

Full doumentation for linker (ld-2.37)
