Android functions providing empty responses about react-native-wifi-reborn HOT 16 CLOSED

Hey @jkaravakis. Even ACCESS_COARSE_LOCATION should do the trick. There is corrently a bug in the connect logic on line 213 and + of RNWifiModule.java

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { conf.SSID = ssid; } else { conf.SSID = "\"" + ssid + "\""; }

This is not correct. This is fixed in our fork https://github.com/inthepocket/react-native-wifi-reborn and there is a PR open. Waiting for @JuanSeBestia to publish it :-).

from react-native-wifi-reborn.

v2.2.2 seems to have addressed the original issue. Many thanks to @eliaslecomte for the excellent work!

from react-native-wifi-reborn.

The current code requires location permission. It can't scan for wifi networks or connect to one starting Android 6 without it.
I've openen a PR: #13 that makes it possible to connect without the permission but this should indeed be highlighted through the documentation better.

What could you see on the console ?, did I get an error?

from react-native-wifi-reborn.

WifiManager.getCurrentWifiSSID()
      .then(ssid => {
        console.log('Your current connected wifi SSID is ' + ssid);
      })
      .catch(err => {
        console.log('Cannot get current SSID!' + err);
      });

getCurrentWifiSSID logs Your current connected wifi SSID is <unknown ssid>

WifiManager.connectToProtectedSSID('wifiNetwork', 'password', true)
      .then(success => {
        console.log('success' + success);
      })
      .catch(err => {
        console.log(err);
      });

I am willing to look into making this more clear:

• update readme
• return an error telling location permission is required to scan when trying without

@JuanSeBestia can you assign me to this?

from react-native-wifi-reborn.

Thank you @eliaslecomte! I've implemented a permissions request with PermissionsAndroid for ACCESS_FINE_LOCATION and the loadWifiList and getCurrentWifiSSID functions are now working. However, I still can't get the connectToProtected SSID function to work. I'm getting the following error now:

Error: Can't connect to wifi!

I'm going to dig into this a bit more, but any thoughts are much appreciated.

from react-native-wifi-reborn.

@eliaslecomte you are awesome! I can confirm it works using your fork. Much appreciated!

FYI regarding coarse access, that did not seem to work for me.

from react-native-wifi-reborn.

I'm having same problems with @jkaravakis and even after defining ACCESS_FINE_LOCATION nothing worked for me.

my logs are same as well,
"Your current connected wifi SSID is "
and
"Error: Can't connect to wifi!"

also I don't know how to get @eliaslecomte 's fork 😞

Hi @mferhatkeles,

I had to use PermissionsAndroid.request to get location permission from the user. Documentation can be founder here: https://facebook.github.io/react-native/docs/permissionsandroid

Essentially you want to run the below function:

PermissionsAndroid.request(
        PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION,
      );

Hope this helps!

from react-native-wifi-reborn.

hello @jkaravakis

async function requestAccess() {
try {
const granted = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION,
//PermissionsAndroid.PERMISSIONS.ACCESS_NETWORK_STATE,
{
'title': 'Wifi networks',
'message': 'We need your permission in order to find wifi networks'
}
)
if (granted === PermissionsAndroid.RESULTS.GRANTED) {
console.log("Thank you for your permission! :)");
} else {
console.log("You will not able to retrieve wifi available networks list");
}
} catch (err) {
console.warn(err)
}
}

this is my function to get it and I can get granted every time. but wifi functions do not work. did you totally fix your problem? can you use connectToProtectedSSID ?

from react-native-wifi-reborn.

@mferhatkeles I don't see anything wrong with your code, have your tried nesting connecToProtectedSSID within if (granted === PermissionsAndroid.RESULTS.GRANTED)? This structure is working for me.

from react-native-wifi-reborn.

@jkaravakis ı just tried this and nothing happened 😞

from react-native-wifi-reborn.

@mferhatkeles there is a problem currently with the connecToProtectedSSID on some Android versions. Can you get the list wifi networks to work?
Did you add the location permission to your android manifest?

from react-native-wifi-reborn.

@eliaslecomte yes I added the permission to android manifest still does not work. Still I might have problem with permission tho. Where should ı call permission function?

from react-native-wifi-reborn.

v2.2.2 is Released!
But i'm ver taired today to check this issue, sorry :(
