BasicReadAndWrite Example got Nullreference exception when reading Analog input

[leoyjw]

Hi, Im using the simple read-and-write example for reading an analog input from my BACNET device through mstp. But I keep getting null reference exceptions when reading the analog input. And I can detect the BACNET device in StartActivity(). And YABE was able to do the reading for the device.
