I want to use a complex native project (https://github.com/SiliconLabs/wireless-xpress) in react native and because i cant recreate the functionality, i want to try and integrate react native on the existing one but i have no idea how to implement that. I've seen some examples on how to create native modules in ios and android but this project is too big to wrap my head around.
The project uses bluetooth low energy to connect to a board on custom hardware and use a terminal via phone.

I have built my react native project using expo and expo go to run it. I now need Bluetooth functionality to scan and take data from a Bluetooth device (to create graphs). Am I able to keep using expo for this or will I have to change to react native CLI to have Bluetooth in my app? Will any expo-related code now be useless if so?
I have not tried any solutions yet and I am looking advice
I would like to add unity into my react native expo app. Since I searched I don't find anything helpful for me and related to my requirement. Is there any Sample/Reference code available for Unity Integration with React native?
Thanks in advance!
ive been in the same place. so currently theres no way to directly communicate it with Unity. But you can always communicate with native android/ios and that in turn communicates with unity. worked with that, and it works pretty well. so your native side should launch the game rather than react native directly starting it.
Basically call a native method in android side from react native --> that in turn starts / calls the unity module .
check this once
Hope this helps. otherwise please connect with me
I am working on an application related to attendance, where multiple employees can mark their attendance on a single android phone. I want to attach an external fingerprint scanner with USB. I am building my application in react native.
I got the solution in Java but I need the solution in react native.
I need the solution like this link but in react native.

You'll need to bridge between React Native (Javascript) and native (Java) code. The docs are pretty good and have specific examples for Android.
One approach would be to fork a react-native biometric integration library (for example https://github.com/hieuvp/react-native-fingerprint-scanner) and replace the underlying native (Java for android) implementation with the code that you found.
I have a question: I'm going to develop an AR app with viro for react native.
Will I be able to publish the project without the Viro Media app that they're suggesting for development?
Of course, you can create an independent Viro app and build it either from Android Studio or by exploiting the React Native CLI, as it is described here.
Remember to use an ARCore supported device to access native modules and the AR functionalities.
I'd like to use Expo's barcode scanner component in a non-expo app that i've already mostly built:
https://docs.expo.io/versions/latest/sdk/bar-code-scanner.html
Is it reasonable to do this? Or is it more reasonable to create a new Expo app then migrate my existing codebase into the new expo app?
My existing app was created using react-ignite, not sure if that is relevant or does not make a difference.
Generally speaking, integrating Expo components with native dependencies (such as the camera) into a non-Expo app is possible, but is a bit tricky, as you'd have to lift the source code from the Expo codebase into your application.
The JavaScript code for these modules exists in the expo/expo-sdk module, and are quite straightforward:
CameraBasedBarCodeScanner
Camera
However, the native module that's required to make the Camera work are embedded within the expo/expo client application, and depends on other parts of the Expo codebase.
Instead, I recommend you use the react-native-camera component, which supports barcode scanning out of the box, and is easier to integrate into a plan React Native application.
