Thank you sonnyyu for your replay. Your post was very helpful. I managed to get a flow data through the WiFi.
Nevertheless, I would have one more question connected with the the data transmission speed.
While Arduino gets : http://arduino.local/arduino/analog/1
it returns value of the analogs in the format : 1024,1024,1024,1024,1024 ( client.print(values) )
In my C# application I am downloading http text and breaking this up text for 5 peaces.
string value = client.DownloadString("http://arduino.local/arduino/analog/1");
The problem is that it takes too much time to get this data from the http. Wifi signal strength is 98%.
Estimated time to get the data from http is 300-500ms. In comparison with the USB data flow - which takes 1,3 ms - the Arduino YUN WiFi speed is very poor.
What would You recon to make it faster. Thank You for your help. :D :D :D :D
