Sensor Drivers on windows 10 give Error debug logs

NTDEV

I have Developed the sensor driver (accelerometer), its opening properly in the sensor info app and values are displayed properly in the sensor info app. But whenever I launch the sensor info app I get following Debug logs on debugview.

ERROR SensorGetFifoMaxSizeV2:PropKeyFindKeyGetUlong failed to get type!:0xC0000225

Following properties I have set during initialization in my sensor driver.

Enumeration Properties:

DEVPKEY_Sensor_Type,DEVPKEY_Sensor_Manufacturer,DEVPKEY_Sensor_Model,

DEVPKEY_Sensor_ConnectionType,DEVPKEY_Sensor_PersistentUniqueId,DEVPKEY_Sensor_Category.

Supported Data-Fields:

PKEY_SensorData_Timestamp,PKEY_SensorData_AccelerationX_Gs,PKEY_SensorData_AccelerationY_Gs,

PKEY_SensorData_AccelerationZ_Gs.

Data is set accordingly,

Sensor Properties:

PKEY_Sensor_State,PKEY_Sensor_MinimumDataInterval_Ms,PKEY_Sensor_MaximumDataFieldSize_Bytes,PKEY_Sensor_Type.

Data field properties:

PKEY_SensorDataField_Resolution,PKEY_SensorDataField_RangeMinimum,PKEY_SensorDataField_RangeMaximum.

Thresholds values set accordingly.

I want to know why this error logs are printed here.

Am I missing any properties or data field to be registered?

STATUS_NOT_FOUND.

0x7E is ERROR_MOD_NOT_FOUND, and 0x490 is ERROR_NOT_FOUND.

These are probably just optional properties.

Hi Jagadish

Upon start, SensorInfo attempts to instantiate all the sensors it was designed to monitor. Some of these sensors may not exist on the system. When SensorInfo tries to open a sensor that is not present on the system, the following errors are logged:

ERROR FindDefaultInterface:CM_Get_Device_Interface_List_Size failed:0x00000000,
InterfaceListSize = 1
ERROR SensorOpenByType:Failed to open sensor error:0x0000007E

These errors are benign (you may not have that sensor - whichever that sensor is - on your machine) and can safely be ignored.

If your accelerometer doesn’t support batching, the following error is also logged:

ERROR SensorGetFifoMaxSizeV2:PropKeyFindKeyGetUlong failed to get
type!:0xC0000225

Batching is optional, so you can also safely ignore this error.

In summary: provided your accelerometer driver works properly and the X, Y, Z data fields are reporting the correct data in SensorInfo, all the errors you are seeing are benign and can be ignored.
