Description

Plugin returns returns "Not avaiable" error on iOS 13 when getConnectedSSID() is called, same application was working just fine on iOS 12. Also checked the app permissions and updated dependencies, but problem persists.

Steps to Reproduce

1. Build Ionic application and install on a device running iOS 13.1.3
2. Connect to any wifi network on the iOS device
3. Trigger the getConnectedSSID() method from anywhere in the code (make sure promise gets called after device is ready) e.g.

WifiWizard2.getConnectedSSID()
      .then(result => alert(JSON.stringify(result)))
      .catch(error => alert(JSON.stringify(error)))

Expected behavior: The method should resolve successfully and result should be shown in the alert message

Actual behavior: The method does not resolve and the catch callback is called, the message shown in the device is "Not available"

Reproduces how often: 100%

Versions

• iPhone 7
• iOS 13.1.3
• WifiWizard2 3.1.1

Getting the same error on iOS 13 when I try getConnectedSSID()

Seems to be related to the Location Permission

[digaus]

Found out some more stuff. NEHotspot is only returning the SSID if you already connected to it through your app.

[digaus]

Here is a fix if anyone wants to test it:

https://github.com/digaus/WifiWizard2/commit/061b681c43129f9abe54e6eaa705930362e1bb55

Just add "cordova-plugin-wifiwizard2": "git+ssh://[email protected]/digaus/WifiWizard2.git#master" to package.json and run npm install

@digaus

The same issues.

In iOS 13.1.3, before calling the plugin, I checked programmatically whether the location service and location permission of the mobile phone were turned on, but the plugin still returned a "Not avaiable" error.

The plugin works fine on any other iOS 13 system, including the latest iOS 13.2.3

Could it be a specific version error of iOS 13.1.3?

Might be the case.

I only did test on the latest version.

Is anyone having any issues connecting to a network in iOS 13.3+?

Seems to occasionally happen there too:

Seems to be a bug in iOS

[jainsuneet]

Does anyone have found the solution to this problem. I am still getting Not Found on iOS 13.3

[zabojad]

Same here. Anything new on this issue?

[angelofan]

@zabojad Is your system version also iOS 13.1.3?

[HusFNS]

@arsenal942 @digaus

is there a fix for this issue? I saw it should be fixed with xcode 11.4 and ios 13.4 but no luck for me. anyone?

[andreareidel]

It's not a very satisfying solution, but I am using the plugin cordova-plugin-geolocation to request the current location of the device when the app starts and if the user accepts the location access, WifiWizard2.getConnectedSSID() returns the correct SSID. Otherwise I am getting Not available.

At the moment this is running fine on iOS 13.5.1.

In general I would be happy to have a solution without location access, because the app has nothing to do with the location and however the user has to accept it, but iOS seems to be restrictive with the wifi information (hint from an apple forum).

@arsenal942 @andreareidel @digaus Call WifiWizard2.getConnectedSSID() will throw Not available error on device of iOS 14 Beta.

The following is the console log:

Then, I tried to switch the npm package to digaus

"cordova-plugin-wifiwizard2": "git+https://github.com/digaus/WifiWizard2.git"

Still throws this error.

I have checked the location authorization and I have connected a WiFi hotspot.

This may be fatal, because Apple will release the official version of its iOS 14 system in the near future.

If I still need to provide any information, I can provide it immediately.

[HusFNS]

there is already a fix available for this in the @digaus fork.

Still throws this error.

What should I do?

[HusFNS]

@angelofan

I am importing it like this.

"cordova-plugin-wifiwizard2": "git://github.com/digaus/WifiWizard2.git#master", "wifiwizard2": "git://github.com/digaus/WifiWizard2.git#master",

Then I deleted everything like node_modules, platforms, .. Just standard things. I also updated xcode to the latest version

Why nehelper sent invalid result code [1] for Wi-Fi information request ?

Did you enable the WiFi information access within your Apple account? You should see the capabilities in XCode as well if they are enabled.

[HusFNS]

@angelofan

I will test this on ios 14 I am using 13

[arsenal942]

Is there a PR containing the fixes from the fork another user did? If so, I will review and merge accordingly.

@arsenal942 @tripflex

The culprit is the "Precise Location" switch in the location authorization. If it is turned off, a Not available error will be returned.

This option is newly added in iOS 14.

Regarding location authorization, Apple has abandoned some APIs and added some Beta APIs. This is a document on Apple's official website: https://developer.apple.com/documentation/corelocation/cllocationmanager

In the cordova-diagnostic-plugin plugin, the same issue was opened: https://github.com/dpa99c/cordova-diagnostic-plugin/issues/402

On iOS 14 when a user grants location authorization to an app, the app is by default only given access to "reduced accuracy" location data. If your app requires "full accuracy" (high-accuracy GPS) location data, you need to request temporary access (you can't request it permanently) via the new requestTemporaryFullAccuracyAuthorization() method. This requires the user to authorise full accuracy each time you need it via a new authorisation prompt which displays the new NSLocationTemporaryUsageDescriptionDictionary plist key. The current accuracy level is indicated by the accuracyAuthorization property of CLLocationManager as CLAccuracyAuthorization constants.

We need to extend this plugin to expose these new methods and constants. This should be done conditionally in a backwardly-compatible way so as not to break builds which use an SDK version lower than iOS 14.

Note: iOS 14 public release date is due ~14 September

Maybe this part of our inspection location can be done using this library? Because checking whether the user authorized the location is not actually a task of our plug-in, it is only necessary to check the necessary process for our plug-in to work properly.

Edit: I removed some of my invalid comments to keep this issue clean.

[angelofan]

Has this issue been resolved?

[cf1991]

iPhone 13pro,IOS 15.4.1,use getCurrentPosition() return "Not available"，can you help solve this problem?
