BleCharacteristicValue class
Represents the value of a Bluetooth characteristic.
This class encapsulates the value of a specific Bluetooth characteristic fetched from a connected device. The value is typically a list of integers, representing bytes of data from the characteristic.
Along with the value, the class provides details about the characteristic's UUID and the Bluetooth device's address from which the value was read.
Instances of this class can be used to easily manage, display, or process the characteristic values in your application.
Example:
BleCharacteristicValue charValue = await readCharacteristic(address, characteristicUuid, timeout);
print(charValue.characteristicUuid); // prints UUID of the characteristic
print(charValue.deviceAddress); // prints address of the device
print(charValue.value); // prints the actual value of the characteristic
Constructors
-
BleCharacteristicValue({required String characteristicUuid, required String deviceAddress, required List<
int> value}) - Constructs a new instance of BleCharacteristicValue.
- BleCharacteristicValue.fromMap(Map map)
-
Factory constructor that creates an instance of BleCharacteristicValue from a map. This is typically used to
convert data coming from the platform side using methods provided by the flutter_splendid_ble plugin.

The actual value of the characteristic.
final
- valueString → String
-
Returns the value converted into a String by treating the
List<int>as a UTF-8 encoded string. This string value may, depending upon your application and the firmware running on the Bluetooth device, be further deserialized as a JSON or Protobuf object.no setter
