Methods
-
Requests permissions to be granted to this application. These permissions
must be requested in your manifest, they should not be granted to your app,
and they should have protection level dangerous, regardless whether they
are declared by the platform or a third-party app.
inherited
-
connect(
Peripheral peripheral) → Future< void> - Establishes a local connection to a peripheral.
-
disconnect(
Peripheral peripheral) → Future< void> - Cancels an active or pending local connection to a peripheral.
-
discoverGATT(
Peripheral peripheral) → Future< List< GATTService> > - Discovers the GATT services, characteristics and descriptors of the peripheral.
-
getMaximumWriteLength(
Peripheral peripheral, {required GATTCharacteristicWriteType type}) → Future< int> - The maximum amount of data, in bytes, you can send to a characteristic in a single write type.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
readCharacteristic(
Peripheral peripheral, GATTCharacteristic characteristic) → Future< Uint8List> - Retrieves the value of a specified characteristic.
-
readDescriptor(
Peripheral peripheral, GATTDescriptor descriptor) → Future< Uint8List> - Retrieves the value of a specified characteristic descriptor.
-
readRSSI(
Peripheral peripheral) → Future< int> - Retrieves the current RSSI value for the peripheral while connected to the central manager.
-
requestMTU(
Peripheral peripheral, {required int mtu}) → Future< int> - Request an MTU size used for a given connection. Please note that starting from Android 14, the Android Bluetooth stack requests the BLE ATT MTU to 517 bytes when the first GATT client requests an MTU, and disregards all subsequent MTU requests. Check out MTU is set to 517 for the first GATT client requesting an MTU for more information.
-
retrieveConnectedPeripherals(
) → Future< List< Peripheral> > - Returns a list of the peripherals connected to the system.
-
setCharacteristicNotifyState(
Peripheral peripheral, GATTCharacteristic characteristic, {required bool state}) → Future< void> - Sets notifications or indications for the value of a specified characteristic.
-
showAppSettings(
) → Future< void> -
Show screen of details about a particular application.
inherited
-
startDiscovery(
{List< UUID> ? serviceUUIDs}) → Future<void> - Scans for peripherals that are advertising services.
-
stopDiscovery(
) → Future< void> - Asks the central manager to stop scanning for peripherals.
-
toString(
) → String -
A string representation of this object.
inherited
-
writeCharacteristic(
Peripheral peripheral, GATTCharacteristic characteristic, {required Uint8List value, required GATTCharacteristicWriteType type}) → Future< void> - Writes the value of a characteristic.
-
writeDescriptor(
Peripheral peripheral, GATTDescriptor descriptor, {required Uint8List value}) → Future< void> - Writes the value of a characteristic descriptor.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
