hi can you please tell me how to access iOS device ip address using xamarin. we are building iOS app in which we want to show device local ip address. I used many other solutions but they didnt work for me.
I found a post about it here: https://forums.xamarin.com/discussion/348/acquire-device-ip-addresses-monotouch-since-ios6-0
it goes as follow:
Try using System.Net.NetworkInformation.NetworkInterface:
foreach (var netInterface in NetworkInterface.GetAllNetworkInterfaces()) {
if (netInterface.NetworkInterfaceType == NetworkInterfaceType.Wireless80211 ||
netInterface.NetworkInterfaceType == NetworkInterfaceType.Ethernet) {
foreach (var addrInfo in netInterface.GetIPProperties().UnicastAddresses) {
if (addrInfo.Address.AddressFamily == AddressFamily.InterNetwork) {
var ipAddress = addrInfo.Address;
// use ipAddress as needed ...
}
}
}
}

GeoCoding GetLocationAsync method return 'KLCErrorDomain Code=8' error for specific address in Xamarin Forms IOS. same address is working in android but IOS only getting error. Here I have tried with below address. Here I have used Xamarin.Essentials Nuget is used for GeoCoding api.
Address: SAINT PETERSBURG, SPE, RU
Below code I have tried for getting position based on address
var locations = await Geocoding.GetLocationsAsync(address);
var location = locations?.FirstOrDefault();
if (location != null)
{
return new double[] { location.Latitude, location.Longitude };
}
I've been trying to connect to a specific wifi through code, but with no succcess.
This is what i've come up with:
public void ConnectToWifi(string ssid, string password)
{
WifiManager wifiManager = (WifiManager)Android.App.Application.Context.GetSystemService(Context.WifiService);
if (!wifiManager.IsWifiEnabled)
{
wifiManager.SetWifiEnabled(true);
}
string formattedSsid = $"\"{ssid}\"";
string formattedPassword = $"\"{password}\"";
WifiConfiguration wifiConfig = new WifiConfiguration
{
Ssid = formattedSsid,
PreSharedKey = formattedPassword
};
var addNetwork = wifiManager.AddNetwork(wifiConfig);
WifiConfiguration network = wifiManager.ConfiguredNetworks.FirstOrDefault(n => n.Ssid == ssid);
if (network == null)
{
Console.WriteLine($"Cannot connect to network: {ssid}");
return;
}
wifiManager.Disconnect();
bool enableNetwork = wifiManager.EnableNetwork(network.NetworkId, true);
}
I've added permissions.
When testing it does turn the wifi on atleast, so i know it works until that point. What seems not to be working is the AddNetwork part.
I appreciate any help i can get!
You are missing one key method - reconnect(). You can read more about it in the WifiManager's docs here
The important part of the documentation is:
Reconnect to the currently active access point, if we are currently disconnected.
So, what you need to do it after you have disconnected and enabled your new network, call in the end this and you will be good to go:
wifiManager.Disconnect();
wifiManager.EnableNetwork(network.NetworkId, true);
wifiManager.Reconnect(); // This is the missing method
NB: Keep in mind that most of the WifiManager's code that you are using is being obsolete starting Android 10. So, if you want to target Android 10, then you will need to write an additional code for the connectivity for devices with Android 10+.
I could get the ssid of the connected wifi to my iPhone. After Installing Xcode 10 and Updating Visual Studio for Mac and Visual Studio 2017, it returns me an empty ssid.
This is my piece of code for getting the ssid:
public override string GetCurrentWiFi()
{
String ssid = "";
try
{
string[] supportedInterfaces;
StatusCode status;
if ((status = CaptiveNetwork.TryGetSupportedInterfaces(out supportedInterfaces)) != StatusCode.OK)
{
}
else
{
foreach (var item in supportedInterfaces)
{
NSDictionary info;
status = CaptiveNetwork.TryCopyCurrentNetworkInfo(item, out info);
if (status != StatusCode.OK)
{
continue;
}
ssid = info[CaptiveNetwork.NetworkInfoKeySSID].ToString();
}
}
}
catch
{
}
return ssid;
}
I tried to add "Access WiFi Information" entitlement for iOS 12 app as it is mentioned here but the app still get an empty ssid:https://forums.xamarin.com/discussion/139476/adding-access-wifi-information-entitlement-for-ios-12-apps
I would be thankful if anyone could help.
RESOLVED: I applied Access WIFI Information for my Apple ID. Then I regenerated my Provisioning profile again and open it in my Xcode. Do not forget to add Entitlements.plist in the Custom Entertainments in the ios Bundle Signing. Now it works correctly.
Updated for iOS 13: Apple announced that iOS 13, the CNCopyCurrentNetworkInfo API will no longer return valid Wi-Fi SSID and BSSID information.
If your app requires valid Wi-Fi SSID and BSSID information to function, you can do the following:
· For accessory setup apps, use the NEHotSpotConfiguration API, which now has the option to pass a prefix of the SSID hotspot your app expects to connect to.
· For other types of apps, use the CoreLocation API to request the user’s consent to access location information.
So, I updated the above solution in the following way:
Add this key to your info.plist:
<key>NSLocationWhenInUseUsageDescription</key>
<string>Your Description</string>
Use the CoreLocation API to request the user’s consent to access location information.
private void GetLocationConsent()
{
var manager = new CLLocationManager();
manager.AuthorizationChanged += (sender, args) => {
Console.WriteLine("Authorization changed to: {0}", args.Status);
};
if (UIDevice.CurrentDevice.CheckSystemVersion(8, 0))
manager.RequestWhenInUseAuthorization();
}
Call the GetLocationConsent() function before calling the "CaptiveNetwork".
To use this function in iOS 12 and later, enable the Access WiFi Information capability for your app .
So you have to check Access WiFi Infomation in appid.
I'm trying to communicate with an Arduino over bluetooth using the Windows.Networking.Sockets namespace for Windows 8.1 Store apps. For some reason PeerFinder can't find the Arduino and the pairedDevices collection is empty. I manually paired the Arduino in the Settings App in Windows, so I know the problem isn't the Arduino code. If anyone can help me fix my code so I can find the Arduino it'd be much appreciated
PeerFinder.Start();
PeerFinder.AllowBluetooth = true;
PeerFinder.AlternateIdentities["Bluetooth:Paired"] = string.Empty;
var pairedDevices = await PeerFinder.FindAllPeersAsync();
int i = 0;
//Look for paired Arduino
while (i <= pairedDevices.Count)
{
if (pairedDevices[i].DisplayName == "HC-05")
{
break;
}
}
I am building a windows phone 7.1 app. I need to find out if the phone is connected to any Wifi and if so, what is its current IP in the local network (ie. 192.168.0.100 like this).
I've been trying to find out these information for some time now. Please help.
I've managed to get the local IP on my console app by using the following code
public void ScanIP()
{
IPHostEntry host = Dns.GetHostEntry(Dns.GetHostName());
foreach (IPAddress ip in host.AddressList)
{
if (ip.AddressFamily == AddressFamily.InterNetwork)
{
String localIP = ip.ToString();
Console.WriteLine(localIP);
}
}
Console.ReadKey();
}
However, I need similar thing done for windows mobile 7 app. Any idea ? Please share.
Do a multicast and listen for replies. Once you identify your multicast message, you can get the IP of the sender (which is yourself). You can use UdpAnySourceMulticastClient to do the multicasting. In case you're not in a wifi network, you will get a socket failure in the EndJoinGroup call. You should handle the exception and pass a specific value indicating you're not in a wifi network.
More info in this blog post by Andy Pennell.
it will provide you the ip address of the phone ...
public static IPAddress Find()
{
List<string> ipAddresses = new List<string>();
var hostnames = NetworkInformation.GetHostNames();
foreach (var hn in hostnames)
{
if (hn.IPInformation != null)
{
string ipAddress = hn.DisplayName;
ipAddresses.Add(ipAddress);
}
}
IPAddress address = IPAddress.Parse(ipAddresses[0]);
return address;
}
