Detailed Description

The DataLoggerService class accesses the Data Logger service of Pokit devices.

Definition at line 22 of file dataloggerservice.h.

Member Typedef Documentation

◆ Samples

DataLoggerService::Samples

Raw samples from the Reading characteristic.

These raw samples are (supposedly) within the range -2048 to +2047, and need to be multiplied by the Metadata::scale value from the Metadata characteristc to get the true values.

Also supposedly, there should be no more than 10 samples at a time, according to Pokit's current API docs. There is not artificial limitation imposed by QtPokit, so devices may begin batching more samples in future. Specifically, the Pokit Pro seems to send 88 samples (in 176 bytes) at a time.

Member Function Documentation

◆ disableMetadataNotifications()

bool DataLoggerService::disableMetadataNotifications ( )

Disables client-side notifications of Data Logger metadata changes.

Instantaneous reads can still be fetched by readMetadataCharacteristic().

Returns true is the request was successfully submited to the device queue, false otherwise.

    return d->disableCharacteristicNotificatons(CharacteristicUuids::metadata);

References DataLoggerService::CharacteristicUuids::reading.

◆ enableMetadataNotifications()

bool DataLoggerService::enableMetadataNotifications ( )

Enables client-side notifications of Data Logger metadata changes.

This is an alternative to manually requesting individual reads via readMetadataCharacteristic().

Returns true is the request was successfully submited to the device queue, false otherwise.

Successfully read values (if any) will be emitted via the metadataRead() signal.

bool DataLoggerService::fetchSamples ( )

Once the Pokit device has processed this request succesffully, the device will begin notifying the Metadata and Reading characteristic, resulting in emits of metadataRead and samplesRead respectively.

    // Note, only the Settings::command member need be set, since the others are all ignored by the

const DataLoggerService::Metadata metadata = multimeterService->metadata();
