Unfortunately prototype device I have prepared is not flawless. During tests I have

noticed specific situations when WCS hangs up and needs reset.

The main case is connected with power supply. When power is insufficient even for

a brief of time communication between computer software and control system becomes

impossible.

Another possibility of hanging up is caused, in my opinion, by errors in WCS surce

code. Despite my very best efforts, mistakes are human thing.

Yet to implement

As we can see in the overview of the WiFly shield there are many possibilities of

expanding our Control system. In my opinion, the most valuable is the power management.

When using this device as a portable power consumption becomes an issue. Thanks to

sleep mode, wake on UART and other available functions, we can significantly extend

work time on battery.

Another not fully implemented feature is the HTTP server. As an example, simple

website is stored inside of the Control System. It gives us opportunity to create separate

interface to manage certain settings or just show status data. Real time clock within WiFly

allows us to use time stamping. Thanks to this login/session algorithms can be

implemented to rise security level of data over HTTP.

To allow being up-to-date with firmware, there is a possibility to implement over-

the-air upgrade with use of the ftp. When thinking about final product this is a worthwhile

solution.

Of course there are plenty not implemented setting from the level of WCC

software. We can connect to the Adhoc networks, manage time or UART parameters or

use UDP protocol instead of TPC/IP. With all of these possibilities really advanced

projects are at out fingertips. The only border is our imagination.
