wifi

I am trying to send some data between 2 raspberry pi's over wifi without them being connected to a network. I want it to work similar to the way beacons and probe requests work, where a broadcast can be sent out the wireless interface. the data I want to send will be the hostname of the device and the time the packet was sent. I've been trying to figure this out for the last few days but I cannot get anything to work without them being on the same network. Is anybody able to point me in the right direction? I'm not too fussed about what language I use. I have been trying python and C with

I have an application which connects to a web service. I can connect to the web service any number of times without any problem using WIFI or 3G provided that I stay loyal to my connection type during the life cycle of my application. That is if I don't switch from WIFI to 3G. If I switches from WIFI to 3G, I can't get a response anymore. My connection just keeps on waiting for response. I tried 4 scenarios below. I'm only having problem with the 3rd scenario. What could be the problem? 1st Scenario: Connection is always on WIFI (Ok) Application connects to a web service using WIFI. Response

I was running some FireBase tests and suddenly I realized Firebase was not working anymore when using mobile data from Chile. At the beginning I thought the problem was my app so I tried to open a Firebase official example but I had no luck (office-mover-demo example). This is what I tried: I connected the phone to my home wifi connection and FireBase works :) I shared the phone’s internet connection to my computer and it did not work :( . This is the error y receive. I emailed Firebase support and they sill don´t have an answer to this strange situation. I asked people from The Netherlands

I have a windows form application in C# and I'm trying to get the host name of all the clients that I have in a list. Given below is a code example by ra00l from this link: GetHostEntry is very slow (I have a similar code made but this one is cleaner) private delegate IPHostEntry GetHostEntryHandler(string ip); public string GetReverseDNS(string ip, int timeout) { try { GetHostEntryHandler callback = new GetHostEntryHandler(Dns.GetHostEntry); IAsyncResult result = callback.BeginInvoke(ip,null,null); if (result.AsyncWaitHandle.WaitOne(timeout, false)) { return callback.EndInvoke(result)

I am making a program to list all the devices who are connected to my Wi-Fi network so that I can see if anyone else is connected. I have found a code for CMD - net view but it lists only the computers connected to my Wi-Fi but not the mobile devices. Is there any other command to list mobile devices connected to my Wi-Fi using CMD. You need an external tool called : Wireless Network Watcher Description : Wireless Network Watcher is a small utility that scans your wireless network and displays the list of all computers and devices that are currently connected to your network. For every

I need to create a wifi hotspot and a DHCP server in Windows 7-8 with Java. I'm developing a software that could be for the user less intrusive and simple that i could. For the first part of my work, I thought to use netsh to create the hosted network and to set static the ip. my current code is this: String[] command = { "cmd", }; Process p = Runtime.getRuntime().exec(command); new Thread(new SyncPipe(p.getErrorStream(), System.err)).start(); new Thread(new SyncPipe(p.getInputStream(), System.out)).start(); PrintWriter stdin = new PrintWriter(p.getOutputStream()); //now I use the stdin
