Arduino Wifly

Hi guys,my project is very simple. I would like khổng lồ use the channeljc.com yun lớn sover data from a sensor to lớn a PC via wifi. However, I don"t have a router và I want lớn use a the ad-hoc connection. I didn"t find much information about it, I only found where I can set the ad-hoc configuration on the advance setting...ok.. & then.... I miss the next step.

Can you help me?? Thanks!!

woodstock:Thank you Jesse for your answer.I read the different documentation but apart from the information about the setting configuration in LUCI interface… unfortunally I have not solved the problem

woodstochồng,are you aware that the default settings for the Yun is to act as an APhường (wireless Access Point)?So, I’m puzzled as to lớn your real problem. Do you want wifi as your primary network medium?Or are you looking for a dependable network. Can you please give us more details.

ThanksJesse


woodstock:I have sầu a doubt: with the Console commvà I need a ssh connection, in your opinion the C# code doesn’t change?

Oh… that would be a problem. This is a straight TCPhường. stream socket. SSH adds an encrypted protocol layer on top of that. This was tested using the straight YunClient, but not tested with Console. I’m sure it won’t work, & I’ve sầu never looked into lớn what it would take to lớn make an SSH connection from C#. I’m afraid I can’t be any help there.

Hi guys… I finally completed my project. THANKS very much for your tư vấn. Now I want khổng lồ mô tả with you the code that I used.

Sketch code: I didn’t use the Console command but the TCPhường. approach with YunClient. (Thanks to ShapeShifter)

#include #include #include #define PORT 255YunServer server(PORT);YunClient client;static boolean clientActive sầu = false;void setup() // Bridge startup Bridge.begin(); hệ thống.noListenOnLocalhost(); hệ thống.begin(); client = VPS.accept();void loop() if (client.connected()) if (!clientActive) //Serial.println("New client connection."); clientActive sầu = true; // Have sầu a connection. Read và emang đến any input lớn the serial port if (client.available()) //Serial.print("From client: ""); //while (client.available()) //Serial.print((char)client.read()); //Serial.println("""); // Skết thúc lớn the client 350 349 348.... 301 350 349..... int x; for (x=350; x>300; x--) client.println(x); delay(100); else // No connection, try to accept one. if (clientActive) Serial.println("Client disconnected."); clientActive sầu = false; client = hệ thống.accept(); C# code: it was not very easy to create a socket and to lớn control the sending data. However in with this code you will not have any problem
