Hi all,

 

I'm getting a NullReference exception in Netduino.IP.LinkLayers.CC3100 when I reference the MFWsStack assembly.  It always happens twice upon power up, and prevents the Wifi from connecting. When I remove the reference and dependent code, it powers up and connects to the WiFi just fine (even have a little web server running on it).  Also tried commenting out all of my code and just inserting Thread.Sleep(Timeout.Infinite) in he Main() method, and with MFWsStack referenced it still does it.

 

There are also some first-chance exceptions of type CC3100SimpleLinkException being thrown:

Exception thrown: 'Netduino.IP.LinkLayers.CC3100SimpleLinkException' in Netduino.IP.LinkLayers.CC3100
Exception thrown: 'Netduino.IP.LinkLayers.CC3100SimpleLinkException' in Netduino.IP.LinkLayers.CC3100
The thread '<No Name>' (0x2) has exited with code 0 (0x0).
The thread '<No Name>' (0x4) has exited with code 0 (0x0).
Exception thrown: 'Netduino.IP.LinkLayers.CC3100SimpleLinkException' in Netduino.IP.LinkLayers.CC3100
Exception thrown: 'System.NullReferenceException' in Netduino.IP.LinkLayers.CC3100
An unhandled exception of type 'System.NullReferenceException' occurred in Netduino.IP.LinkLayers.CC3100

Any help appreciated.
