to the Info.plist -
Add
NSMicrophoneUsageDescription
to the iOS project's Info.plist if using audio
Important: Ask for Bluetooth permissions first using react-native-permissions!

// To subscribe to nearby devices broadcasting
nearbyAPI.subscribe();
// To check if the nearby API is subscribing.

Install the dependencies in the root folder
yarn
Generate an API Key from the Google Developer Console
- Go to the Google Developers Console.
- Create or select a project to register your application with.
- Click Continue to Enable the API.
- On the Credentials page, create a new API Key. (No key restrictions are needed for this example)
- Copy/Paste your key in example/index.js and in the example AndroidManifest.xml
- To run the example app, the packager must have the
projectRoots
reordered for the example/ directory. In another terminal window:
yarn start --projectRoots <FULL-PATH-TO-REPO>/react-native-nearby-api/example,<FULL-PATH-TO-REPO>/react-native-nearby-api
yarn run:android
adb reverse tcp:8081 tcp:8081
cd example ios/
bundle exec pod install
- Open
example.xcworkspace
- Add your IP to
AppDelegate.m
jsCodeLocation = [NSURL URLWithString:@"http://<IP-ADDRESS>:8081/index.bundle?platform=ios&dev=true"];
-
In another terminal window:
yarn start
-
Run on device
NOTE: If you receive a
duplicate symbols for architecture
error through Xcode, this is a known issue. A work around is to run./renameLogger.sh
afternode_modules
have been installed and you've attempted to run in Xcode.
