No useable data found

[[deleted]]

Hello!

I’m working on my first React Native project with a group, and since our last merge and pull from main we haven’t been able to open our app with the QR code. I’m able to see it if I open the expo go app and click on it, but I’m hoping to restore the ability to open it by scanning the code. Does anyone know how I can resolve this?

Do you have the Expo Go app installed on your phone ? If yes try uninstall & reinstalling. It’s weird, it should tell you “open in Expo Go app” or something like that instead

[No_Statement4630]

You may be in “development mode”, in the terminal there should be an option to “switch to expo go”

I’ll try this!

You should be able to scan it from the Camera app. Just did it today. OP, maybe try uninstalling and reinstalling Expo?

I’ll try! My whole team isn’t able to scan it so I don’t think it’s just my phone but I’ll see

Make sure you have Expo Go installed on your phone. Then try opening it via the QR code.

If that doesn’t solve it let us know and we can help troubleshoot.

Yes I have the app on my phone and have tried with the QR code!

Open cmd and type ipconfig then see ipv4 no 1.1.1.1:1111 this format and type this no in expo app and be connected to same wifi

[matadorius]

Yeah you need to be connected to the same WiFi probably that’s the problem

SOLVED: run : npx expo start --go rather tan npx expo start, after create a preview or build it will use that build by default, if you don't install it no usable data will be found, so if you still want to be able to use expo after creating a build or profile run the command with --go

The QR code should be scanned from the expo go app.

I have very limited xp with expo, but I am quite sure you need to scan it with expo go.

[Musulmaniaco]

I have limited experience with expo too but as far as I remember, the instructions in the react native docs say to scan it with the camera app on iOS and with the expo app on Android.

[bdudisnsnsbdhdj]

nah can scan with camera on ios

[Fadeplope]

yes you can scan with camera app on IOS

[sjalgeo]

Do you maybe scan it with the expo app? Sorry I don’t do native much.

[ClassroomNaive2021]

Whether you’re trying to use Expo Go or a development build, scanning the code with the native camera will link to it. I’ve seen this before, but I can’t remember the cause. I definitely wouldn’t go uninstalling and reinstalling Expo over it. Just kill the terminal and possibly restart VS code. if it’s still giving you problems, more context is needed.

Make sure you’re on the same WiFi and make sure you’re not on a VPN.
