  Hi, how can i differentiate a data packet from a command packet in the
host controller? If i receive only bytes, i must check the first 12 bits
from my packet to see if it is a connection handle?

for H4 UART transport they are prefixed with a one byte data type. For
USB transport they come in over different endpoints on the USB bus. All
other transports use similar mechanism.
