but my problem is not parsing, my problem is that i have no idea if some of these numbers are the real Yaw, pitch and roll angles, because i have try to find out if any of them are these angles by moviming the imu but my conclusion is that NO.
I have seen that in some tutorials not using arduino UNO, the obain a String as YPR = 23,23,34 and i am obtaining just these 9 numbers that i think that they are the 9 degrees of freedom of the imu without processing
