Description
When using the WSEN-HIDS driver in one-shot mode, performing a power_off() / power_on() cycle between measurements leads to a timeout on the next read_one_shot() call.
The first measurement after initialization works correctly, but subsequent measurements after a power cycle fail with a WSENHIDSTimeoutError.
This suggests that power_on() does not fully restore the internal state of the sensor after power_off(). The driver initialization (init) configures the sensor (averaging, BDU, calibration), but this configuration is not reapplied after a power cycle.
As a result, the sensor appears to be powered on electrically but not fully operational for triggering a new one-shot measurement.
