Using react-native-ble-plx with expo

Summary

This repo demonstrates how to use react-native-ble-plx in a managed expo project.

FAQ

• Do i need to eject? No
• Can i use the expo go app? Also no
• But how does it work? Running native code (non expo stuff, react-native-ble-plx in this case) requires a custom build of expo's go app, called a dev-client

Requirements

To build this app you need access to expos eas system. Dont worry, it's free*. You can either build in their cloud or on your own machine (building for iOS requieres a macOS Device!).

*At least for a limited amount of builds.

OR

• eas build --profile development --platform android --local

And then follow the eas instructions.

To build a standalone app you need to swith the profile to "preview":
