The Allocation Error is from your SDcard. When you read from or write to the card mostly the first time after power up.

With the Netduino Plus V2 is one problem solved, more memory. One to go the serial invert Rx.Tx. We want to beat the Arduino in every way. We are looking forward when the Netduino V2 is available in the Netherlands. Ellen.

Hi Ellen,

The best option is to use the new NETMF 4.3 release. You can use the beta SDK--but it won't change the firmware on your board. The first NETMF 4.3 beta firmware should be available this month.


Thank you Chris, we are waiting for the 4.3 beta this month. We hope the internet glitch is than solved.

@Travor, you did not install (correct) the Netduino driver, please read all the steps to install at the begin.

Hello Chris may I have your attention. We have notice that the Netduino Plus hangs when the socket.Connect is called when the internet connection is down after the N+ starts up. The only option was a reset. I have placed a full working example here: You can run the code and on the same time stop the internet connection in your router. Then you see the error. My question, can you confirm this "bug" and do you have a workaround for it because writing to the Internet is het core of my program. Sometimes the internet connection is down here for a few minutes. I did a attempt with 4.3 beta but deploying to the N+ was without any succes.

Now Baxter, I can exactly tell you what is wrong.!

The Netduino will hang when you have a internet connection but after a while the IP provider stops the connection for a reason.

Do While True

                Debug.Print("begin " & DateTime.Now.ToString)


                Dim IPEndPoint As New IPEndPoint(Dns.GetHostEntry("").AddressList(0), 80)

                Using Host As Socket = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp)

                    Host.SetSocketOption(SocketOptionLevel.Tcp, SocketOptionName.NoDelay, True)
                    Host.SendTimeout = 3000
                    Host.ReceiveTimeout = 1000

                    'WITH internet connection it wil run perfect, but now without internet (after you had a connection)'
                    '  and still on the local network then..........'

                    Debug.Print("WHEN INTERNET connection fails after a time, than the NETDUINO HANG!!!!")

                    Host.Connect(IPEndPoint)  'It will hang here.!'

                    Debug.Print("Oké, stil connection")

                End Using

            Catch ex As Exception
                Debug.Print("error " & ex.Message) 'no error will show here'
            End Try
