8.  In the web browser you should now be on the new IP address that the network 

assigned to the dock.  

9.  Navigate to the uC Console tab and set the baud rate from the drop down tab.  This 

must match the WiFi Baud of the measurement device.  Default WiFi Baud is 115200. 

 

Figure 7-5 - Microcontroller Console 

 

10. You can now communicate with the device over WiFi using serial commands. A 

TCP/IP connection is made using the assigned IP through Port 23.
