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

Pokit Bluetooth API errata: The Android app can turn Pokit Pro LEDs on/off. Perhaps that is handled by an undocumented use of this characteristic. Or perhaps its via some other service.

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.

◆ 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.
}

Not all Pokit devices support the Status::batteryStatus member, in which case the member will be initilialised to the maximum value supported by the underlying type (ie 255) to indicate "not set"
