Flutter package to communicate with bluetooth device

How to Use

To use bluetooth_advanced, follow the following steps:

Step1: Adding plugin dependency

add the plugin to your pubspec.yaml file:

bluetooth_advanced: [latest_version]

Step2: Importing the package.

import the plugin in [your_file].dart

import 'package:bluetooth_advanced/bluetooth_advanced.dart';

Step3: Init configuration details

here it is importance to set UUIDs that are similar to those used in your server device. UUIDs are unique identification information of your device which identifies the services provided by bluetooth device. Your application will connect to that device using this through standard protocols.

final _bluetoothAdvanced = BluetoothAdvanced();
print(await _bluetoothAdvanced.getDataCharactersticUUID());
print(await _bluetoothAdvanced.getServiceCharactersticUUID());
await _bluetoothAdvanced
          .setServiceCharactersticUUID([your_service_uuid]);
await _bluetoothAdvanced
          .setDataCharactersticUUID([your_data_uuid]);

Step4: Initialize Bluetooth

• returns a stream which you can continously listen to:

_bluetoothAdvanced.initBluetooth();

Step5: Scan Devices

• returns a stream which you can continously listen to the following states:

STATE	DESCRIPTION	DATA TYPE/FORMAT
SCANNING_STARTED	Started Scanning a paired device	String
SCANNING_FINISHED_WITH_NO_DEVICE	no device found	String
[device_address] , [device_name]	return device address,name in comma seperated format	String: "01:23:45:67:89:10,MyBluetoothDevice"

_bluetoothAdvanced.scanDevices();

Step6: Connect Device

• returns a stream which you can continously listen to the following states:

STATE	DESCRIPTION	DATA TYPE / FORMAT
DEVICE_RECOGNIZING	Recognized the device with necessary information	String
DEVICE_CONNECTING	trying to connect with the device	String
DEVICE_CONNECTED	established connection to the device	String
DEVICE_DISCONNECTED	connection aborted	String
DEVICE_CONNECTING_FAILED	trying to connect result failure	String

_bluetoothAdvanced.connectDevice();

Step7: Listen to Data

• returns a stream which you can continously listen to the following states:

STATE	DESCRIPTION	DATA TYPE / FORMAT
DEVICE_DATA_INITIATED	attempting data handshake with device	String
DEVICE_DATA_CONNECTING	trying to connect with the device to lsiten data	String
DEVICE_DATA_CONNECTED	established connection to the device to listen data	String
DEVICE_DATA_AVAILABLE	data is received and available in a format	String : "DEVICE_DATA_AVAILABLE:this is tha data received"
DEVICE_DATA_DISCONNECTED	data connection was revoked	String

_bluetoothAdvanced.listenData();

Step8: Revoke Connection

this will revoke connection with the device, if you dont call this function it will keep running in the background and will keep receiving data.

_bluetoothAdvanced.dispose();
