BluetoothProbe

Scans for nearby, visible Bluetooth devices and collects a Bluetooth measurement that lists each device found during the scan.

Used for the ConnectivitySamplingPackage.BLUETOOTH measure. Uses a PeriodicSamplingConfiguration for the interval and duration of the scan. Use a BluetoothScanPeriodicSamplingConfiguration to filter by services and remoteIds. If the scan fails, the measurement holds an Error.

Constants

DEFAULT_TIMEOUT

int const DEFAULT_TIMEOUT

Default scan timeout in milliseconds (4 seconds), used if no duration is configured.

Properties

bufferingStream

1. @override

Stream get bufferingStream

override

The stream of events to be buffered. Must be specified by sub-classes.

remoteIds

List<String> get remoteIds

The remote device ids to filter the scan on. Empty if no BluetoothScanPeriodicSamplingConfiguration is used.

services

List<Guid> get services

The service UUIDs to filter the scan on. Empty if no BluetoothScanPeriodicSamplingConfiguration is used.

Methods

getMeasurement

1. @override

Future<Measurement?> getMeasurement()

override

Subclasses should implement / override this method to collect the Measurement. This method will be called every time data has been buffered for a duration and should return the final measurement for the buffered data.

Can return null if no data is available. Can return an Error if an error occurs.

onSamplingData

1. @override

void onSamplingData(

1. dynamic event

)

override

Handler for handling onData events from the buffering stream.

onSamplingEnd

1. @override

void onSamplingEnd()

override

Handler called when sampling period ends.

onSamplingStart

1. @override

void onSamplingStart()

override

Handler called when sampling period starts.
