Sending data over TCP from arduino to python -

-

I am struggling with this for a few hours and in reality it is not known where to go from here . I've got an Ardino Uno with a WiFi shield attached to the network, and the Ubuntu laptop connected to the same network. I am using arduino to connect to the network.

I can send data from my laptop to arduino and print it successfully using: sudo nc -l 25565

I Also trying to do the same thing with nc using the following Python code which is also being run as sudo : P> 

  #! / Usr / bin / env python import socket TCP_IP = '127.0.0.1' TCP_PORT = 25565 BUFFER_SIZE = 1024 s = socket.socket (socket.AF_INET, socket.SOCK_STREAM) s.bind ((TCP_IP, TCP_PORT)) s.listen ( Data Conn.recv (BUFFER_SIZE) data: Brake print 'Data received:', data conn.send ('1) (conn, addr) = s.accept () print' connection address: ', while corrected: ECHO ') conn.close () s.close ()   
 but it just hangs on  (conn, addr) = s ()  . Using the client python script on the same laptop, I can connect to the above server and I can send the data that the server then prints.  
 I just do not know why  nc  will be printed by arduino but the Python server will not script, even if it will print from a python client what ardino library fails to follow some standard Which might be the dragon's hope? thank you in advanced.   
 
 
 No, the arduino library is not " failed to adhere to some standards  ".  
 Your program is bound to the  localhost  interface, IP address  127.0.0.1 . This means that the programs running on only one PC will be able to connect to your Python server.  
 Try it:  
  s.bind (('', TCP_PORT))   
 Reference:  
:  
 
 For IPv4 addresses, two special forms are accepted instead of a host address: The empty string represents  INADDR_ANY , and the string  '& Lt; Broadcast & gt; Displays   INADDR_BROADCAST . Behavior is not available for backward compatibility for IPv6, therefore, if you want to support IPv6 with your Python programs, you want to avoid these.   
 
 To notice some things: We have used socket.gethostname () so that the socket can be visible in the outside world. If we used s.bind (('localhost', 80)) or s.bind (('127.0.0.1', 80)), then we would still be a "server" socket, but the same machine Was visible within. S.bind (('', 80)) Specifies that the socket is accessible from the machine to any address.

I am trying to learn PDO, now I have written this small code, but it gives me a serious error: < P> Fatal error: Call a member function at a non-object dot () ... $ con = new mysqli ("127.0.0.1", "root", "", "csvdangercheck"); $ Query = $ con- & gt; ("Id,` var1`, `var2`) values ​​(" id,: var1,: var2) ";); $ query- & gt; bypass pattern (': id', $ id); $ query- & gt; BindParam (': var1', $ VAL1); $ Query- & gt; bindParam (': var2', $ val2); $ Query-> Executed (); I Trying to use print_r ($ con-> errorInfo ()) but Fatal error: Undefined method mysqli :: errorInfo ( ) ... can someone tell me what am I missing?

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
