Peripheral class
Representation of a unique peripheral
This class allows for managing the connection, discovery, retrieving Services, Characteristics and Descriptors and has convenience methods for manipulation of the latter two.
Only connect(), observeConnectionState(), isConnected() and disconnectOrCancelConnection() can be used if peripheral is not connected.

Methods
-
characteristics(
String servicedUuid) → Future< List< Characteristic> > -
Returns a list of discovered Characteristics of a Service identified
by
servicedUuid. -
connect(
{bool isAutoConnect = false, int requestMtu = NO_MTU_NEGOTIATION, bool refreshGatt = false, Duration? timeout}) → Future< void> - Connects to the peripheral.
-
descriptorsForCharacteristic(
String serviceUuid, String characteristicUuid) → Future< List< Descriptor> > - Returns a list of Descriptors for Characteristic matching specified UUIDs.
-
disconnectOrCancelConnection(
) → Future< void> - Disconnects from this peripheral if it's connected or cancels pending connection.
-
discoverAllServicesAndCharacteristics(
{String? transactionId}) → Future< void> - Discovers all Services, Characteristics and Descriptors of this peripheral. Must be done prior to any other operation concerning those.
-
isConnected(
) → Future< bool> - Returns whether this peripheral is connected.
-
monitorCharacteristic(
String serviceUuid, String characteristicUuid, {String? transactionId}) → Stream< CharacteristicWithValue> - Returns a stream of notifications/indications from Characteristic matching specified UUIDs.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
observeConnectionState(
{bool emitCurrentValue = false, bool completeOnDisconnect = false}) → Stream< PeripheralConnectionState> -
Returns a stream of
PeripheralConnectionState. -
readCharacteristic(
String serviceUuid, String characteristicUuid, {String? transactionId}) → Future< CharacteristicWithValue> - Reads value of Characteristic matching specified UUIDs.
-
readDescriptor(
String serviceUuid, String characteristicUuid, String descriptorUuid, {String? transactionId}) → Future< DescriptorWithValue> - Reads value of Descriptor matching specified UUIDs.
-
requestMtu(
int mtu, {String? transactionId}) → Future< int> - Requests new MTU value for current connection and return the negotiation result on Android, reads MTU on iOS.
-
rssi(
{String? transactionId}) → Future< int> - Reads RSSI for the peripheral.
-
services(
) → Future< List< Service> > - Returns a list of Services of this peripheral.
-
toString(
) → String -
A string representation of this object.
override
-
writeCharacteristic(
String serviceUuid, String characteristicUuid, Uint8List value, bool withResponse, {String? transactionId}) → Future< Characteristic> -
Writes value of
Characteristicmatching specified UUIDs. -
writeDescriptor(
String serviceUuid, String characteristicUuid, String descriptorUuid, Uint8List value, {String? transactionId}) → Future< Descriptor> -
Writes value of
Descriptormatching specified UUIDs.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
