hi kris, i get yaw reading just 180 degree range from north to south counterclockwise and from north clockwise doesn't give any response ! also when i flip the sensor the yaw stop giving any response and advise ?

Did you calibrate your sensors? How?

i calibrate it as you mention in this article https://github.com/kriswiner/MPU6050/wiki/Simple-and-Effective-Magnetometer-Calibration

now the yaw reading is fine but it is affect by the other reading i.e when rotate the sensor in other direction the yaw changes why is that ?

You are not feeding the Madgwick fusion algorithm data in the proper order, or your sensors are not calibrated properly, or you have crappy sensors.
