Setup Description

Getting the createClient is null error. I followed the documentation as seen on the website but I still have the same issue.

TypeError: Cannot read property 'createClient' of null, js engine: hermes at node_modules\react-native\Libraries\Core\ExceptionsManager.js:null in reportException at node_modules\react-native\Libraries\Core\ExceptionsManager.js:null in handleException at node_modules\react-native\Libraries\Core\setUpErrorHandling.js:null in handleError at node_modules\@react-native\polyfills\error-guard.js:null in ErrorUtils.reportFatalError at node_modules\metro-runtime\src\polyfills\require.js:null in guardedLoadModule at node_modules\metro-runtime\src\polyfills\require.js:null in metroRequire at http://10.0.2.2:19001/node_modules/expo/AppEntry.bundle?platform=android&dev=true&minify=false&app=com.syncre.windowblinds&modulesOnly=false&runModule=true:null in global

Steps to Reproduce

  1. creating new BLEManager just creates the error

Since you are using expo did you follow these instructions? https://github.com/dotintent/react-native-ble-plx#expo-sdk-43

Remember this part that it's one of most important:

Then you should build the version using native modules (e.g. with npx expo prebuild command). And install it directly into your device with npx expo run:android.

dominik-czupryna-withintent commented 1 year ago

@garciavalter is right but @syncre02 Could you describe your installation process step by step? Maybe I missed something in the documentation.

syncre02 commented 12 months ago

Nevermind, the issue was that I didn't initalize it properly (I have to ask for premisisons first). Sorry for the delay on the reply.

bj97301 commented 11 months ago

The permissions issue wasn't the fix for me. I needed to rebuild the app and install a new expo dev client thingy on my phone with the latest package.

thank you, @bj97301! My project is not an Expo project, but I also experienced this issue and it was resolved only after rebuilding app in Android Studio.
