Add Wifi SSID to the connection info

[takosunil]

Describe the Feature

NetInfo.isConnected.addEventListener only works when wifi is turned on/off. I am looking to listen to an event when wifi switches from one network to another. Can anyone have some solutions or any workarounds? Thanks in advance.

Possible Implementations

NetInfo.isConnected.addEventListener("connectionSwitch", listener)
or
NetInfo.isConnected.addEventListener("wifiConnectionSwitch", listener)

Thanks for the request.

Just to confirm, are you looking for a way to listen for when the phone connects to a network with a different SSID?

If so, this might be something we can add to the ConnectionInfo which is returned from NetInfo. getConnectionInfo and NetInfo.addEventListener.

If you would like to contribute a PR to add this then that would be amazing.

Implementation details
For future reference, on iOS it is available through this function and on Android through this method.

I am also needing the WIFI SSID and IP to my APP. Is it being developed???

@FabioJfa If there are any updates then they will be posted on the relevant issues. Contributions are always welcome

A package with this functionality exists at https://github.com/pusherman/react-native-network-info. Maybe @pusherman might want to merge it here or at least provide guidance?

I have a private package for work that interfaces with most of the network info params (ssid, ip address, signal strength, etc.) but currently it's only for Android. I've opened #122 that adds 4 params to the details object: ssid, ip, signal strength, and carrier (for cellular). If anyone has done this for iOS and wants to add on, that'd be helpful! I don't primarily work in iOS right now so it would take me a bit longer to do.

I think we would need to request additional permissions and capabilities to get some of this information. On Android, we would need the location permission(coarse or fine) to get information on available SSID's and on iOS we would need Networking Capability Wifi Info. We may already be requesting some of this but if not we'd need to add this to the project.

I'd love this feature integrated too, but CNCopyCurrentNetworkInfo is going to be deprecated in iOS 13 and there is no replacement to read SSID in sight.

So it might be a realistic expectation of Android, but not of iOS.

Android support added in #122 🎉

[dawnmist]

Apple have altered the use of CNCopyCurrentNetworkInfo in iOS 13 to require one of:

• The app uses Core Location, and has the user’s authorization to use location information.
• The app uses the NEHotspotConfiguration API to configure the current Wi-Fi network.
• The app has active VPN configurations installed.

If none of those are present, it'll report a dummy SSID (iOS12-) or null (iOS13+) instead of the real one. It's not actually deprecated, just needs the app to request certain permissions in order to retrieve the real SSID, which could be left up to the react-native app to determine if they need that information and thus need to request permissions/capabilities for it.

That being the case, can the possibility of adding this for iOS too please be revisited?

@dawnmist 👋 You're in luck! A PR for that is open here #210
