This is a quick overview of the API and usage; continue reading below for setup instructions and more comprehensive examples. If you are having problems please file an issue. Install the relevant platform package.

See table at the top of the readme for supported versions. If you are having issues discovering devices when scanning, try adding coarse location permissions.

Android has inconsistent behavior across devices and adding this permission sometimes helps. If you are only using BLE in the foreground, when your app is active, you don't need to do any further setup for iOS. EnableAdapter to work, then in your main Activity add:. Subscribe to work, then in your calling Activity add:.

Each platform project has a static method BluetoothLowEnergyAdapter. ObtainDefaultAdapter which you call from your platform project and provide to your application code using whatever strategy you prefer dependency injection, manual reference passing, a singleton or service locator, etc. All the examples presume you have obtained the IBluetoothLowEnergyAdapter as per the setup notes above, e. In use-cases where you are not scanning for advertisements but rather looking to connect to a specific, known, device:.

You can provide information for the GUIDs representing services, characteristics, and descriptors with KnownAttributes. You can also create a new KnownAttributes with all the above adopted attributes already populated:. You can add a log "sink" to receive each log entry which you can then write to the console or a logging system of your choice. Also, each platform's static BluetoothLowEnergyAdapter. ObtainAdapter method has an overload that takes an ILog. If no log is provided the default log SystemLog.

Instance is used, but you could provide your own entire logging implementation if you really wanted to.

The library is available on jcenter and Maven-Central repositories. Add the following dependency to your build. It is common, that you application needs to parse the received data. Let's have a look at HRM profile. The Heart Rate Measurement characteristic specifies the structure of data sent by a remote sensor.

To make working with standard profiles easier, this library allows to replace the code above with:. Such code looks simpler, is easier to read, relies on a tested library and marks fields that may not be present in the packet with Nullable annotation.

All data parsers have unit tests and should work properly. Unfortunately, I couldn't find any working device or test data in order to verify the implementation. Please, follow our coding style.

The library is and will be based on BSD-3 License. Any feedback is welcome. Use Issues to report bugs or submit suggestions.

Broadcast Bluetooth Low Energy beacons directly from Android 5. A beacon scanning library. A minimum-priority notification allows the user to stop all currently running beacons, for the following reason. If your app crashes or the beacons service is killed and restarted, all saved active beacons will restart advertising.

When this number is reached, new beacons will fail to start. It's best to make sure you stop or delete a beacon after you no longer need it, but the notification assures the user is in control.

Initialize the library. Usually you would do this when onCreate is called in either your Application, Activity, or Service. If you had any previously active beacons that you created and saved, they will resume. After adding a beacon, it will begin to advertise immediately if Bluetooth is on or when it gets enabled. Because starting up a beacon is an Android async operation, if there's an error, a broadcast is sent by the service.

See the listening for events section for how to handle this. All beacon constructors support extra arguments, to set their initial properties like Advertise mode, TX power, lock key, or name. The library supports full production-ready EID beacons. The beacon's advertised EID will automatically update when needed, using scheduled Android system Alarms, so with zero battery impact.

An EID beacon first needs to be registered. For testing only, you can fake a registration and use that to provision an EID beacon. That will take care of all the ugly details. The final configured beacon may be different than the initially configured one, because its type may change e. You receive the configured beacon in a callback after the owner disconnects.

The beacon will already be enabled for advertising. If you provide an initial configurable beacon, the final beacon will also be automatically saved, if the original beacon was saved. If the final beacon is of a different type, the original beacon will be deleted, and its Lock Key, name, and other basic properties will be copied to the new beacon. The provided beacon will become connectable, so most probably it will no longer advertise while someone is connected.

At least on some devices, if another BLE advertiser starts while you are connected, the connection may be dropped. Every Eddystone beacon has its own Lock Key. If you want a beacon to survive between service or app restarts, you should save it to persistent storage. The default save method will also enable the beacon to advertise. For all beacons, you can update a beacon's TX power, broadcast frequency, name.

Some beacons properties are immutable example: EID identity key or clock offset. The general pattern to update one or more properties:. Only if really needed e.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

The library does not provide support for scanning for Bluetooth LE devices. For scanning, we recommend using Android Scanner Compat Library which brings almost all recent features, introduced in Lollipop and later, to the older platforms. The library may be found on jcenter and Maven Central repository.

Add it to your project by adding the following dependency:. A BleManager instance is responsible for connecting and communicating with a single peripheral. Multiple manager instances are allowed. The first step is to create your BLE Manager implementation, like below. First, override a BleServerManager class and override initializeServer method. Some helper methods, like characteristic The BleServerManagerCallbacks.

You may initiate your connection there. The latter one is a set of useful parsers and callbacks for common Bluetooth SIG adopted profiles. The libraries are available on jcenter, but if you need to make some changes, clone all 3 projects, ensure the path to :ble and :ble-common modules are correct in settings.

A library that makes working with Bluetooth LE on Android a pleasure. Java Just a guess! When I scan for BLE peripherals without any filter, I see my custom peripheral, but the moment I add a scan filter like the following, I don't see it anymore:.

How do scan filters work exactly? What is the requirement for a peripheral to be accepted by such a filter? Hmm, odd. Do you receive anything in the scan callback, or an error, or just nothing at all? Here is a more complete version of the code that does not produce any result, nor any error.

The callback is just never called. Skip to content. Instantly share code, notes, and snippets. Code Revisions 60 Stars 66 Forks Embed What would you like to do?

An Android library providing APIs to interact with beacons. Please visit the project website for how to use this library. If you want this library to work with proprietary or custom beacons, see the BeaconParser class.

It allows Android devices to use beacons much like iOS devices do. An app can request to get notifications when one or more beacons appear or disappear.

An app can also request to get a ranging update from one or more beacons at a frequency of approximately 1Hz. The project website has full documentation including Javadocs.

For support head to StackOverflow rxandroidble. Read the official announcement at Polidea Blog. It's your job to maintain single instance of the client. You can use singleton, scoped Dagger component or whatever else you want. The library does not handle managing the state of the BluetoothAdapter.

Direct managing of the state is not recommended as it violates the application user's right to manage the state of their phone. See Javadoc of BluetoothAdapter.

It is the user's responsibility to inform why the application needs Bluetooth to be turned on and for ask the application's user consent. It is possible to show a native activity for turning the Bluetooth on by calling:. On Android it is not always trivial to determine if a particular BLE operation has a potential to succeed. To be sure that the scan will work only when everything is ready you could use:.

From BluetoothDevice. Auto connect concept may be misleading at first glance. With the autoconnect flag set to false the connection will end up with an error if a BLE device is not advertising when the RxBleDevice establishConnection method is called. Setting the auto connect flag to true allows you to wait until the BLE device becomes discoverable. The RxBleConnection instance won't be emitted until the connection is fully set up.

From experience it also handles acquiring wake locks, so it's safe to assume that your Android device will be woken up after the connection has been established - but it is not a documented feature and may change in the future system releases. Be careful not to overuse the autoConnect flag.

On the other side it has negative impact on the connection initialization speed. Scanning window and interval is lowered as it is optimized for background use and depending on Bluetooth parameters it may and usually do take more time to establish the connection.

If you want to observe changes in device connection state just subscribe like below. On subscription you will receive the most current state instantly. By default RxBleLog uses logcat to print the messages.

You can provide your own logger implementation to forward it to other logging libraries such as Timber. Every error you may encounter is provided via onError callback. Each public method has JavaDoc explaining possible errors. From different interfaces, you can obtain different Observable s which exhibit different behaviours. There are two types of Observable s that you may encounter. Whenever you are no longer interested in keeping the connection open you should dispose it which will cause disconnection and cleanup of resources.

For example observeStateChanges does emit only a single value and finishes in exactly one situation — when Bluetooth Adapter is not available on the device. There is no reason to monitor other states as the adapter does not appear during runtime. We encourage you to check the package com.
