Use a little—or a lot. You can use React Native today in your existing Android and iOS projects or you can create a whole new app from scratch. React primitives render to native platform UI, meaning your app uses the same native platform APIs other apps do.

Give it a try Run this npx react-native init MyTestApp.With tons of stars on Github and the glowing reviews, it is hard to ignore React Native as a framework of choice to build native apps these days. The idea of unified codebase across different OS platforms seems promising, but is it also a good choice for non-trivial apps? A wearable app is an example of such non-trivial apps.

Developing a wearable app in native code is an obvious choice, but how about doing it in React Native? We were in a collaboration with our partner to develop a mobile application for their wearable product lines fitness tracker band and smart watch.

The app would extensively communicate with the wearable device using BLE. Consequently, it's important to have the communication part handled right. Besides phone-device communication, the user experience was also of high degree of importance. The goal was to let users have consistent UI experience across different platforms, at least on iOS and Android.

React Native became a strong option due to the possibility of meeting the UI goal. However, it was pretty much unclear if using JavaScript via React Native to bridge the Bluetooth communication with the underlying OS platforms was a good idea especially since we would deal with a custom BLE data protocol.

We began shopping for the existing react-native libraries to see if there was an immediate fit for our implementation plan.

There were not so many Bluetooth libraries for React Native, hinting the use case for similar app was uncommon. After digging up, we concluded the search with the following libraries, which we thought might be suitable: react-native-ble-plxreact-native-ble-managerreact-native-bleand react-native-bluetooth-serial. However, it's worth mentioning that the library along with react-native-ble-manager follow certain structure that we prefer in the BLE implementation.

After experimenting with the existing React Native Bluetooth libraries, we ended up implementing the Bluetooth bridging functionalities by ourselves. One of the reasons was the complexity of the BLE data protocol as for example having multiple phases for data transmission beyond the traditional read, write, and notify characteristics.

The decision was tough one, especially when imagining the tremendous effort needed to implement the BLE native bridge for the target OS platforms. The common usage of BLE for wearable is for transferring data between the LE device the wearable with the phone.

Data transfer occurs in client-server mode, where the wearable plays the role as the server the data owner and the phone acts as the client the data requester. The data transfer will be possible if the phone knows the "address" of the wearable and the specific service it is interested in. To do so, the phone will need to first discover the wearable from the network and then connect to it in order to start the data transfer flow. For the device discovery, the role of the phone is known as "central" while the wearable as "peripheral".

Think about a radar in an aircraft that scans the surrounding to detect if there is any object of interest nearby. After the discovery process is completed, the phone will have gathered the necessary information needed to connect to the device and start the data transfer.

Upon completing the data transfer, the common practice is to close the connection to the device in order to conserve energy. The phone may also save the information about the device it was connecting to so that in the subsequent connection, the phone does need to rescan and rediscover the device again. The basic documentation on writing native module on iOS and Android is already available on the official documentation page. The native module consists of methods that when called from Javascript will execute the native code block that it is interfacing with.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

For Android, you need to put the following code to AndroidManifest. This method will create an event listener and send it though as a component prop and it will remove all event listeners on componentWillUnmount as well.

If id is omitted, the first connected device will be disconnected. Indicates the specific connected bluetooth device connection status. If id is omitted, it will return the connection status of the first connected device. Restore services and set them to default services BluetoothSerial. This module supports multiple devices connection, as you can see in API Methodsmost of the connection, IO, and buffer methods have id parameter that you can pass and specify which bluetooth device that you want to control.

This method gives the ability to call group of API methods instead of pass id parameter at the end of each methods. You get object of message and device. You get object of device id and data.

Therefore we decided to create dedicated ReactiveX based libraries for iOS and Android which allows user to highly reduce their implementation boilerplate required by native stacks. However, our work is not done yet, because there is a new player on a field. React Native is a framework developed by Facebook which lets you build mobile apps using only JavaScript language.

That allows all platform specific issues to be solved by separate teams and the effort required to to do so is not doubled. Additionally due to Rx composability and great centralized error handling mechanisms, the implementation of this React Native Bluetooth Low Energy library takes very little time, which can allow us to reduce the number of bugs resulting in a greater confidence about the overall correctness of the code.

This approach carry few advantages. Second, the use of Promises is very straightforward for new users. Furthermore lays a technical reason, which is a direct limitation of bridging values between JS interpreter and native modules. We can only pass basic types such as numbers, strings, arrays and object and use oneshot callbacks or events for broadcasting.

In consequence these restrictions forced us to use Promises, pass UUIDs as strings and values in Base64 format, which is not ideal, but still working. Check if React Native is the right tech for your project Learn more.

There are two categories of API definitions which are currently used :. All of functions are defined in BleManager object which has to be imported and created before use:. Most of values returned by API calls are in a form of an object.

For example a characteristic is defined as follows:. All four methods below do the same thing:. Last thing which is crucial to know before moving to an example is that all errors are bubbled from most basic calls to most specific calls.

That way the user of our React Native Bluetooth library will not need to cancel any promise manually when such situation takes place. As an example we will present parts of a very simple program which connects to TI CC SensorTag and reads all value changes from temperature, accelerometer, humidity, magnetometer, barometer and gyroscope sensors. For each of them there are two characteristics: one for enabling sensors and one for reading values.

Utility functions will help with updating them:. First of all we need to wait for BLE stack to init properly. This step is required on iOS if we want to use it very early. After this event scanning is triggered and we are searching for sensor tag device:.

Function scanAndConnect uses promises to chain multiple asynchronous operations and handle potential error in one place for convenience.
