android-wifi

I am developing an Android Application that employs WiFi (Direct) for service discovery and P2P peer discovery/connection. My development enviromment is as follows:- Android Studio 3.0 Beta 4 Build #AI-171.4304935, built on August 29, 2017 JRE: 1.8.0_152-release-915-b01 x86_64 JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o Mac OS X 10.11.6 My Gradle build:- apply plugin: 'com.android.application' apply plugin: 'realm-android' android { compileSdkVersion 26 buildToolsVersion "26.0.1" defaultConfig { applicationId "com.research.wifi_direct" minSdkVersion 19 targetSdkVersion 26 versionCode 1

I am doing my Master thesis at the moment on WiFi positioning and in order to test my algorithms I needed to collect some data. To do this I have written a short and very simple program for Android which simply collects the RSSI for all availible access points found by each scan and saves them to file. I have set up a BroadcastReceiver that listens on the event WifiManager.SCAN_RESULTS_AVAILABLE_ACTION and I use a Timer , here called tim, to initiate scans with a WifiManager , called wifi as follows: tim.schedule(new TimerTask(){ @Override public void run(){ wifi.startScan(); } }, 0, 1000);

Do any of you Android gurus out there know of any open source code to create a WifiConfiguration from a given ScanResult ? It would be helpful. Indeed, line 483 (/624) of my capture (mid April 2012) of the Android source of WifiConfiguration.java is a commented-out constructor intended to do exactly this, with a big TODO wondering whether it's worth implementing (see quote below). I motion yes, can I hear a second? The main challenge I see (which is actually the brunt of this question) is how to interpret the ScanResult.configuration String. can I expect just a simple list of things like [WPA2

What is the difference between mWifiManager.startScanActive() and mWifiManager.startScan() . What is the difference between active scan and passive scan ? Passive scanning listens to beacons sent by the access points. That means waiting for the beacon to be sent (usually a few seconds). An active scanning will emit probes to those APs immediately. please note that an active scan will consume more energy and as "ordinary" wifi access points broadcast their beacons several times per second, an active scan is rarely needed. e.g. requesting a list of wifi networks in reach takes approx 0.7 seconds

I have a ESP8266 chip which is connected to the microcircuit. When chip gets value "200" the light is starting to blink 4 times and than it returns "100" value. I need to make an Android app using Java which will connect to the ESP8266 chip, send data to it and will get value "100". I don't know what library I should use to deal with it. Please, help me, how can I do that? I think it is not the most hard question here. For your Controller you dont need any Libary. You just can use the serial AT Commands: http://www.electrodragon.com/w/ESP8266 After setting up your ESP like this: In your App

In my Application I want to send files through WiFi to multiple users if they are using the same WiFi connection Without TCP. how to get the list of the users who are connected to a specified wify. I have tried with Samples But I didn't get anything . Wi-Fi peer-to-peer (P2P) allows Android 4.0 (API level 14) or later devices with the appropriate hardware to connect directly to each other via Wi-Fi without an intermediate access point (Android's Wi-Fi P2P framework complies with the Wi-Fi Alliance's Wi-Fi Direct™ certification program). Using these APIs, you can discover and connect to other
