RE: There is a problem with the calculation of angles.

I don't know the reason yet, but I've divided the formula little by little and it's printed out properly.

I think the angle value is being calculated slightly wrong, but I'll try this part more.

Thank you.

    double accel_x = accel_values.x;
    double accel_y = accel_values.y;
    double accel_z = accel_values.z;
    
    double test1 = sqrt(pow(accel_x,2) + pow(accel_z, 2)); //OK
    double test2 = atan(accel_y / test1); //OK
    double test3 = test2 * RADIAN_TO_DEGREE; //OK
    printf("Angle_X : %lf\n", test3); 

    double test4 = sqrt(pow(accel_y,2) + pow(accel_z, 2)); //OK
    double test5 = atan(-accel_x / test4); //OK
    double test6 = test5 * RADIAN_TO_DEGREE; //OK
    printf("Angle_Y : %lf\n", test6);

Hello,

I would recommend you to debug out with breakpoints to figure out the actual reason.

Without details, difficult to answer your question.
