wifi

问题 I need to turn on or off the wifi in the iphone. Any ways of doing it? Or is it forbidden (private framework) 回答1: All applications written with the public SDK are sandboxed. They only have access to the properties and data which Apple deems feasible to use within that sandbox. I am afraid Wi-fi doesn't come in the list Pls take a look at this SO question iPhone Wi-Fi Manager SDK and this discussion 来源： https://stackoverflow.com/questions/5963880/turn-wifi-on-off-for-iphone-from-an

问题 I have some binaries running on ubuntu that control various devices like onboard/usb wifi/bluetooth chips. Some chips will require additional drivers. My guess is that merely installing the drivers to the docker image is not enough, and the host OS must have the drivers. Is this correct? If yes, why does the docker image need any drivers at all if the host already does? How can docker image correctly delegates to host? Do these need to be hardcoded for each driver on each host OS? Also from

问题 The Withings iOS app has the ability to obtain your wifi settings and pass it to the body scale via Classic Bluetooth (see screenshot below). From what I learnt it's a feature only available through the MFi program, which the Withings Scale is. I'm building an app that talks to external BLE devices. Since MFi is not required for BLE devices, I'm wondering if there's a way to do the same thing with CoreBluetooth or other frameworks? From Apple's MFi FAQ page: "Accessories which connect to an

问题 I want to transfer messages/file from desktop application to the Android device. My question is that can I connect desktop Wifi device with the Android WiFi device without any use of internet connection. I want to use it just like Bluetooth. Is this possible/feasible or not? If it is possible then how can I implement it? And what is the message limit to transfer message/file? Note : I wanted to use it as real time application. Kindly suggest me any good approach and if possible then how to do

问题 I am making an App and I need to get the internet speed!I can find the wifi speed with WifiInfo clasd but I couldn't find any code or library to get the mobile data speed! Should I use libraries or there is classes in Android available? 回答1: It is hard to determine the mobile speed precisely, but you can estimate the speed based on the connectivity type (EDGE, HSPA): public static boolean isConnectedFast(final Context context) { final NetworkInfo info = getNetworkInfo(context); return (info !

问题 So I am working on this app that will get the location of a wifi hotspot by just detecting it using the sensor wifi of the phone (The phone is not actually connecting to the hotspot wifi, it just detect). I was doing some preliminary research before start developing the app, and it seems that the Google Geolocation API will do the work for me. However, it is not free (at least what I understood after reading through the API). I had checked other apps that detects wifi hotspot, and I am just

问题 I am building an Android app and I use the code below to detect whether there is a network connection. It works well and detects both mobile and WIFI networks. My problem is how to detect an actual internet connection. The code below returns true when connected to WIFI however the WIFI might not necessarily be connected to the Internet. The code protected boolean checkInternetConnection() { ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); // test

问题 Building a desktop version of my mobile app and providing the user syncing over wifi. Everything works great in the simulator - no problems resolving net services (which are published by the desktop app) or noticing when services become unavailable. The problem is when I run the app on the phone services are discovered and resolved (sometiems) but the NSNetServiceBrowser never notices when a service becomes unavailable. When this happens the net service browser constantly finds a net service

问题 Using: selenium webdriver, rubygems, appium, android and ios devices The app I am testing has a button which becomes enabled only when connected to a specific wireless network. I'd like to create a script which will check if the button is active or not vKioskStatus = element.enabled? puts(vKioskStatus) If it is not active, then I'd like to change wifi networks. Is that possible to automate changing networks on a mobile device? UPDATE I'm receiving the following error when trying to use

问题 In my app i have some NSURLConnection.sendAsynchronousRequest but because of that if the user has wifi disabled the app crashes. Is there a way to detect if the wifi is disabled so i can do something like that: if(wifi is enabled) { NSURLConnection.sendAsynchronousRequest } 回答1: Found the answer in this blog post: Step 1: Add "SystemConfiguration" framework to your project Step 2: Add this function to your project: func isConnectionAvailble()->Bool{ var rechability =
