Javier,
It can be very confusing! First, you need to work through every step of

(QPSK) tutorial. It uses 2 bit symbols and 4 samples per symbol.
The BPSK tutorial uses 1 bit symbols and 4 samples per symbol. The
For those of you who have been asking questions about BPSK, I have
created
https://wiki.gnuradio.org/index.php/Simulation_example:_BPSK_Demodulation,
which is a follow-on to the QPSK tutorial. Questions and comments are
welcome!
