Question: QMI8658 example gets 1/2 of true acceleration value when gyro is disabled

Sketch: QMI8658_GetDataExample

Normal use case:
when both gyro and accel are enabled - the getAccelerometer() function gives correct acceleration value

Issue:
when gyro is disabled like that:

#if 0
    qmi.configGyroscope(
        /*
        * GYR_RANGE_16DPS
     
< --- skipped --->

    // In 6DOF mode (accelerometer and gyroscope are both enabled),
    // the output data rate is derived from the nature frequency of gyroscope
    qmi.enableGyroscope();
#endif

• then reported acceleration value is a half of true value.

The workaround is to enable the gyro all the time like the SoftRF did ...
But could we avoid that and get correct acceleration value regardless if the gyro is on or off ?

This may be related to the fact that the Accelerometer's ODR has different values when used alone than with the gyro on. see from documentation.
