问题 As far as I know, essentially WIFI direct is enabled by a soft AP. My question: can the underlying WIFI module work as a WIFI station and as a WIFI direct endpoint simultaneously? That means, we hope that the WIFI module can communicate with a mobile phone using WIFI direct, and at the same time connect to a router as a WIFI station. Is it possible? and how widely and strongly is this case supported in technology? 回答1: You can if your wifi driver supports multi-role . This feature, available

问题 I have a small program that trying to connect to a wifi network. It enables the wifi on the device then if it's the first time that is connect to the certain networkss It loads the device wifi in order to select and add the password for connection.

问题 Does anyone know how to determine the active network type at the specific moment: 2G , 3G or WiFi . For example, at a specific moment there could be enabled 3G , but the used network type could be 2G . 回答1: The SCNetworkReachability interface can help you with that. Basically, you create a so-called reachability reference and then call SCNetworkReachabilityGetFlags on it to get information about the connection. The returned flags include kSCNetworkReachabilityFlagsIsWWAN , which tells you

问题 I have to connect my app with server using either wifi (if it is available), or gprs (if wifi is not available). Here is my code to check the connection availability public static final boolean isConnectionAvailable(Activity a) { ConnectivityManager cm = (ConnectivityManager)a.getSystemService(Context.CONNECTIVITY_SERVICE); State mobile = cm.getNetworkInfo(0).getState(); State wifi = cm.getNetworkInfo(1).getState(); if (wifi == NetworkInfo.State.CONNECTED || wifi == NetworkInfo.State

问题 I want to write an application that it can record the wifi hotspot's location we are accessing and display them in map. But the problem is - how do I get wifi hotspot's location? I think I can use the wifi signal to get the wifi hotspot's location, but it may not be very accuracy at first time. And if there is no other solution, I could record the location of GPS when access wifi hotspot at the first time. 回答1: You'll not be able to find the hotspots location and you'll not be able to

问题 I am writing an android app which will connect to a specific WPA access point, when connected, it will issue a http call. It will not save the network config. I have read almost every post on stack overflow on connecting to wifi network but can't find the answer which works for me. Here is the code I am using to connect.. WifiConfiguration wc = new WifiConfiguration(); wc.allowedAuthAlgorithms.clear(); wc.allowedGroupCiphers.clear(); wc.allowedPairwiseCiphers.clear(); wc.allowedProtocols

问题 I am trying to find out how I can list all of the available wireless networks in Python. I am using Windows 8.1. Is there a built-in function I can call, or through a library? Please kindly show me the code which prints the list. 回答1: You'll want the subprocess module and a windows command: import subprocess results = subprocess.check_output(["netsh", "wlan", "show", "network"]) A little extra to just get SSID's. results = results.decode("ascii") # needed in python 3 results = results.replace

问题 I am building an application reading the signal strength of each available Wifi access point. I've written code like: wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE); // Get WiFi status WifiInfo info = wifi.getConnectionInfo(); textStatus.append("\n\nWiFi Status: " + info.toString()); // List available networks List<WifiConfiguration> configs = wifi.getConfiguredNetworks(); However, I have two problems: In debugging, configs only contains one connection. However, I can see that
