The way you said didnt work so well it loose some bytes and sometimes get wrong values..
The way i did works great but if i change Baud Rate 9600 to 115200 it works lot faster, but sometimes miss some characters i dont no why!! if i set a delay(20) works correctly but i dont want a delay.. how can i fix this?
