error opening a device or linter warnings

[kmpm]

When running this application (with my own credentials) I always end up with status error opening a device
and it seems as there is some issues with closing capture twice that might affect things.

I can still scan, but this is not what I expect.

Seems as if useEffect is running multiple times (which it should when content on the page changes) but that messes up things really bad.

This might be my own fault since I added dependencies to useEffect and onCaptureEvent but without them the linter complains about missing dependencies.

src\App.js
  React Hook useCallback has missing dependencies: 'decodedDataList', 'deviceMap', and 'devices'. Either include them or remove the dependency array  react-hooks/exhaustive-deps
  React Hook useEffect has missing dependencies: 'closeCapture' and 'onCaptureEvent'. Either include them or remove the dependency array              react-hooks/exhaustive-deps

I will rename the issue accordingly.

Hi @kmpm, I wonder on which platform you're running this? Do you have the Socket Mobile Companion running? (requirement for running this app on Windows or Android) or do you have Socket Mobile Rumba App? (requirement for iOS device)

[kmpm]

I have a Androd 10 tablet running the Companion and the webpage in Chrome.
Developing on Windows 10 x64 connected to the tablet via ADB and using the remote inspect feature of Chrome on Windows to see the console and stuff from Chrome on Android.
This isn't a big issue since I could just ignore the linting warnings or disable them, but I can't have both linting without warnings AND a application that doesn't "behave".
