Flutter Bluetooth

Codemagic build status

NOTE: This is the updated version of the app (using flutter_bluetooth_serial 0.2.2). This version has much fewer bugs and provides a lot of functionality.

IMPORTANT NOTE [January 1, 2021]:

A much optimized and production release version of this app is available, called Connect (supports both Android and iOS devices).

Learn more about it here.

This flutter app will help you to connect to Bluetooth Devices (like, HC-05). You can send messages to the bluetooth module and perform various operations. By default, the app has only on and off functionality for any paired bluetooth devices, but you can add as many functionality as you want.

Initially, you will have to give location permission to the app. As for discovering as well as for connecting to the paired devices, location permission is required as Bluetooth transmission shares some location data.

Add this dependency in pubspec.yaml:

dependencies:
  flutter_bluetooth_serial: ^0.2.2
