Member Function Documentation

◆ deviceCharacteristics()

StatusService::DeviceCharacteristics StatusService::deviceCharacteristics ( ) const

Returns the most recent value of the Status service's Device Characteristics characteristic.

The returned value, if any, is from the underlying Bluetooth stack's cache. If no such value is currently available (ie the serviceDetailsDiscovered signal has not been emitted yet), then a null result is returned, which can be checked via the returned DeviceCharacteristics::firmwareVersion, like:

const DeviceCharacteristics characteristics = service->deviceCharacteristics();
if (!characteristics.firmwareVersion.isNull()) {
    ...
}

Here is the call graph for this function:

◆ deviceCharacteristicsRead

StatusService::deviceCharacteristicsRead ( const StatusService::DeviceCharacteristics & characteristics )

signal

This signal is emitted when the Device Characteristics characteristic has been read successfully.

See also: readDeviceCharacteristics

◆ deviceName()

QString StatusService::deviceName ( ) const

Returns the most recent value of the Status services's Device Name characteristic.

The returned value, if any, is from the underlying Bluetooth stack's cache. If no such value is currently available (ie the serviceDetailsDiscovered signal has not been emitted yet), then a null QString is returned.

Here is the call graph for this function:

◆ deviceNameRead

StatusService::deviceNameRead ( const QString & deviceName )

signal

This signal is emitted when the Device Name characteristic has been read successfully.

See also: readDeviceName

◆ deviceNameWritten

StatusService::deviceNameWritten ( )

signal

This signal is emitted when the Device Name characteristic has been written successfully.

See also: setDeviceName

◆ deviceStatusRead

StatusService::deviceStatusRead ( const StatusService::Status & status )

signal

This signal is emitted when the Status characteristic has been read successfully.

See also: readDeviceStatus

◆ flashLed()

bool StatusService::flashLed ( )

Flash the Pokit device's LED.

Returns true if the flash request was successfully queued, false otherwise.

Emits deviceLedFlashed() if/when the LED has flashed successfully.

Note: This operation is only supported by Pokit Meter devices. Pokit Pro devices will report an Bluetooth ATT error 0x80.

Here is the call graph for this function:

◆ readCharacteristics()

bool StatusService::readCharacteristics ( )

overridevirtual

Read all characteristics.

This convenience function will queue refresh requests of all characteristics supported by this service.

Relevant *Service::*Read signals will be emitted by derived class objects as each characteristic is successfully read.

Implements AbstractPokitService.

Here is the call graph for this function:

◆ readDeviceCharacteristics()

bool StatusService::readDeviceCharacteristics ( )

Read the Status service's Device Characteristics characteristic.

Returns true is the read request is succesfully queued, false otherwise (ie if the underlying controller it not yet connected to the Pokit device, or the device's services have not yet been discovered).

Emits deviceCharacteristicsRead() if/when the characteristic has been read successfully.

Here is the caller graph for this function:

◆ readNameCharacteristic()

bool StatusService::readNameCharacteristic ( )

Read the Status service's Name characteristic.

Returns true is the read request is succesfully queued, false otherwise (ie if the underlying controller it not yet connected to the Pokit device, or the device's services have not yet been discovered).

Emits deviceNameRead() if/when the characteristic has been read successfully.

Here is the caller graph for this function:

◆ readStatusCharacteristic()

bool StatusService::readStatusCharacteristic ( )

Read the Status service's Status characteristic.

Returns true is the read request is succesfully queued, false otherwise (ie if the underlying controller it not yet connected to the Pokit device, or the device's services have not yet been discovered).

Emits deviceStatusRead() if/when the characteristic has been read successfully.

Here is the caller graph for this function:

◆ setDeviceName()

bool StatusService::setDeviceName ( const QString & name )

Set's the Pokit device's name to name.

Returns true if the write request was successfully queued, false otherwise.

Emits deviceNameWritten() if/when the name has been set.

Here is the call graph for this function:

◆ status()

StatusService::Status StatusService::status ( ) const

Returns the most recent value of the Status service's Status characteristic.

The returned value, if any, is from the underlying Bluetooth stack's cache. If no such value is currently available (ie the serviceDetailsDiscovered signal has not been emitted yet), then the returned StatusService::Status::batteryLevel member will be a quiet NaN, which can be checked like:

const StatusService::Status status = statusService->status();
if (qIsNaN(status.batteryVoltage)) {
    // Handle failure.
}
