To use it, you need to enable the Hotspot capability in your App Capabilities (Adding Capabilities). Quick working example : NEHotspotConfiguration *configuration = [[NEHotspotConfiguration alloc] initWithSSID:@“SSID-Name”]; … Read more
The world has changed since this question was asked, and the answer is now the Android Open Accessory Development Kit. It won’t solve the problem for existing USB devices, but it makes it possible to create new devices that can use an Android device’s USB connection.
Actually you’re checking for whether Wi-Fi is enabled, that doesn’t necessarily mean that it’s connected. It just means that Wi-Fi mode on the phone is enabled and able to connect to Wi-Fi networks. This is how I’m listening for actual Wi-Fi connections in my Broadcast Receiver: public class WifiReceiver extends BroadcastReceiver { @Override public void … Read more
WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE); if (wifiManager.isWifiEnabled()) { // wifi is enabled } For details check here
android.net.wifi.WifiInfo.getSSID? WifiManager wifiMgr = (WifiManager) getActivity().getSystemService(Context.WIFI_SERVICE); WifiInfo wifiInfo = wifiMgr.getConnectionInfo(); String name = wifiInfo.getSSID();
You are correct that this is currently not natively supported in Android, although Google has been saying it will be coming ever since Android was officially launched.

Look at android.provider.Settings for a series of Intent actions you can use to launch various settings screens (e.g., ACTION_WIFI_SETTINGS). EDIT: Add the coding line. startActivity(new Intent(Settings.ACTION_WIFI_SETTINGS));
I listen for WifiManager.NETWORK_STATE_CHANGED_ACTION in a broadcast receiver if (WifiManager.NETWORK_STATE_CHANGED_ACTION.equals(action)) { NetworkInfo netInfo = intent.getParcelableExtra (WifiManager.EXTRA_NETWORK_INFO); if (ConnectivityManager.TYPE_WIFI == netInfo.getType ()) { … } } I check for netInfo.isConnected(). Then I am able to use WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE); WifiInfo info = wifiManager.getConnectionInfo(); String ssid = info.getSSID(); UPDATE From android 8.0 onwards we wont … Read more
FSPL depends on two parameters: First is the frequency of radio signals；Second is the wireless transmission distance. The following formula can reflect the relationship between them. FSPL (dB) = 20log10(d) + 20log10(f) + K d = distance f = frequency K= constant that depends on the units used for d and f If d is … Read more
