Netduino Plus Network Problem

Hello,

I have got a problem with my netduino plus. I would like to communicate via Ethernet with a pc. In the netduino I configure a static IP Adress. After I powered up the netduino it sometimes doesn`t build up a connection to the pc. So I can`t ping the netduino plus. When I reconnect the board sometimes it works and sometimes it doesn`t work. So my first thought was that I have a problem in the programm. So I delete the program and I have the same problem again. Can anybody help me with this problem ?

Hi Bernd,

 

Which Netduino Plus do you have v1 or v2?

Which firmware is installed?

 

With the Netduino Plus v1 and the older firmware v4.1, the Ethernet only worked if the remote device was already active.

So the Netduino would have to be turned on after the other device, and after the Ethernet cable was connected.

Upgrading to v4.2 firmware fixed this for me.

Hello Paul, I have the Version 1. And I have install the Firmware Version 4.2.0.1 . I have also Problems with the WinUsb driver. Sometimes the NP1 is not detects by Win7. When I download the program and are in the debug mode Ethernet is going well. Otherwise I have to powered up the board again and sometines the Board is detect by the ping command and sometimes not.I have same problem with the WinUSB driver too.

I think I have found the problem. So  when I powered up the Wireless N-Adapter Netgaer WNCE2001 and the NP1 together the NP1 doesn't get a IP-Adress. Before I am looking for a hardware solution I have tested a software solution:

While True   Onboard_LED.Write(False)   Thread.Sleep(1000)   If (Eth0(0).IPAddress = "192.168.178.33") Then   Exit While   Else   Eth0(0).ReleaseDhcpLease()   Thread.Sleep(5000)   Eth0(0).RenewDhcpLease()   Onboard_LED.Write(True)   Thread.Sleep(10000)   End If   End While

But now I have the problem that when I would like to Renew the IP-Adress it doesn't work. The NP1 always get IP 0.0.0.0 . I don't know where the problem is. Does anybody have got a suggestion ?

I am not sure but I think there is a bug: 

Sub main()

While True

 If (Eth0(0).IPAddress = "192.168.178.33")) Then   Onboard_LED.Write(Not Onboard_LED.Read)   End If

  Thread.Sleep(1000)

End while

End Sub

When I debug the netduino the LED is blinking. When I stop Debugging and reboot the NP1, when the LED is not blinking but I can ping the Netduino with the IP Address 192.168.178.33. Thats strange I think or not ?

So I have make still some test. But I didn't get the right IP-Adress from the NetworkInterfaceClass, when didn't debug the netduino. Does anybody made a same experience with the this class ? Is the NP1 in the debug mode in the TinyCLR. Or is where a problem to get the right adress in the TinyCLR. Or does anybody have an another idea to the renew the address when DHCP failed during power up the system ?

hi, i have some problems with ethernet port. My device info are:

Have any of you figured this one out?  I seem to be running into the same issue.
