Results

 

I attempted to use both VMware Fusion and VirtualBox, both running Windows 10, to see if I could connect via a VM to the Azure Sphere module. It's necessary for this device to communicate with devices through Virtual Machines. Many companies run virtual machines to control and run their systems. I first attempted to utilize VMware Fusion without any luck. I have VMware tools installed and was able to plug in other USB devices and it functioned. I decided to install VirtualBox to see if I would be able to use the module through VirtualBox.  I was able to set up and install AzureSphereSDK on my VirtualBox machine. I then followed the steps for setting up the sphere module to connect with my WiFi. Below are my results:

 

Figure 1: Logging into my Azure account and claiming the module.

Figure 2: Connecting the module to WiFi.

 

From here the user can take the module and hook whatever system or machine can accept a data cable or a USB cable. This would allow for remote control and monitoring via WiFi.

 

Conclusion

 

This module can be very helpful for companies that have equipment or systems that cannot communicate via traditional methods. This device basically makes any system or machine an IoT device, securely via the azure infrastructure. As stated above I had issues using VMware Fusion but was able to program the module using VirtualBox. I also needed to supply my own USB to micro USB cable to program the module. The module to lightweight and small which would be very easy to install on machinery or equipment.
