GetMyWifiIP error

[Rusty]

The below code has been working for a while and now it fails with:

GetMyIP error: (ErrnoException) libcore.io.ErrnoException: bind failed: EACCES (Permission denied)

The code is as follows:

Sub GetMyIP As String
    Dim IP As String = ""
    Try
        Dim Server As ServerSocket
        Server.Initialize(TCP.Port, "MyIP")
        IP = Server.GetMyWifiIP
        'IP = Server.GetMyIP 
        Server.Close
    Catch
        Log("GetMyIP error: " & LastException)
    End Try
    Return IP
End Sub

I recently upgraded to 2.71. I don't know if this is part of the issue, but would appreciate any advice.
Thanks,
Rusty

Can you remove the Try / Catch and post the full error message from the logs? Have you set the manifest to be read-only?

Thanks Erel.
No, I haven't set the Manifest to read only...should I?

No, I haven't set the Manifest to read only...should I?

No.

The problem is that you are initializing ServerSocket with a restricted port number. I guess that you only use ServerSocket to call GetMyWifiIP. If this is correct then you should not initialize ServerSocket at all. You can add an 'ignore comment to ignore that warning.

Yes, I only want to acquire the IP address.
I use it in my UDP broadcast data gram to establish a connection with a host. It is embedded within my UDP message.
Is there another/better way to merely acquire the IP Address of the tablet?
Thanks,
Rusty
BTW, removing the initialization does cause it to get the IP address successfully.
Thanks again, Erel
