no motor controller connected

From what i understand is when running that is it is taking back and forth because the rx and tx lights are blinking pretty fast and it does come back with the false voltage,temp,rudder values( have those disabled in the motor.ino . The only changes i made to the motor.ino was for the defines of those 3 disabled and define VNH2SP30 and changed the crystal to 16hmz because im using an nano. I know i have a working bt-2 because i tested it without the nano and it works
