Runner

Hello all! please just forget about this post. I have checked the IP´s am MAC address with MFdeploy. In the startup of my main function I was setting the new IP address for the Netduinos. unfortunately I have not recognized a function call to one of the classes I have written at the beginning. In the "lost" class I have had a function which was setting the MAC address. Really thanks for your help and from now on I will improve my code documentation! btw: UDP is working fine. Connection to both of the Netduinos is working! You guys are really great! Thanks

MAC, IP and networkport of all devices are different! I have checked this several times... Trying to switch my code to TCP protocol. This will cost data transfer rate (UDP is faster cause there is no handshake), but i hope it will fix the communication problem

Hey!

Sorry was ill the last days.
Here some code:

System.Net.Sockets.Socket LVSocket = null;
System.Net.IPEndPoint LVEndpoint = null;
System.Net.Sockets.Socket uCSocket = null;
System.Net.IPEndPoint uCEndpoint = null;

// Path of the init File at the Sd Card
System.String Path = @"\SD\Config_INIT.txt";
// DEFAULT values if SD Card is not found or not inserted

// SETTINGS for Netduino #1
System.String LabViewIP = "192.168.1.20";                 
System.Int32 NetworkPort = 49001;                 
System.String NetduinoIP = "192.168.001.21";

// SETTINGS for Netduino #2
// System.String LabViewIP = "192.168.1.20";                 
// System.Int32 NetworkPort = 49002;                 
// System.String NetduinoIP = "192.168.001.22";

The program checks for an config file at the SD Card (works fine)
If no SD Card detected it will continue with:

System.Net.IPAddress IPLabview = System.Net.IPAddress.Parse(LabViewIP);
System.Net.IPAddress IPNetduino = System.Net.IPAddress.Parse(NetduinoIP);

Microsoft.SPOT.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces()[0].EnableStaticIP(NetduinoIP, "255.255.255.0", "192.168.0.0");

if (uCEndpoint == null)

{
  uCSocket = UDPConnector.RecieveSocket(uCSocket);
  uCEndpoint = UDPConnector.RecievePoint(uCSocket, uCEndpoint, IPNetduino, NetworkPort);
}

if (LVSocket == null)
{
  LVSocket = UDPConnector.SendSocket(LVSocket);
  LVEndpoint = UDPConnector.SendPoint(LVSocket, LVEndpoint, IPLabview, NetworkPort);
}

byte[] Recieved = UDPConnector.getMessage(uCSocket);

BTW I´m using CAT5 cables

Hey Markus, I´m sorry but the solution i mentioned above isn´t working.. But it sounded like a good reason for the failure... Have to leave to the university but a small update to the Network config: Netduino #1 IP: 192.168.1.21 Port: 49001 Netduino #2 IP: 192.168.1.22 Port: 49002 Laptop: IP: 192.168.1.20 Port: 49001 and 49002 The Laptop is running a Lab View program which opens 2 UDP protocol ports (both same IP but different ports) same result as before... everything is connected to a switch hard- and software works fine with just one Netduino connected.

ok one device per port....found it.. thanks
