with AVR Studio and just execute Build/Rebuild All item from the main menu.
The WSNDemoApp.hex and WSNDemoApp.srec image files will be then generated.
Low-Power, Peer-to-peer and Ping-Pong applications are described in details in [4].
In case of any operational problem with your system please check the power first, and
make sure that all of your equipment is properly connected.
Check if your PC conforms to the minimum system requirements (see Section 4.2).
Check if the PC interfaces (COM, USB) are present and drivers are installed.
Check on LED indication of a node if it is not responding or behaving unusually. Make
sure the DIP switches are set according to the application running on the board.
You can retest the particular node as described in Section 4.7, if needed.
You may be required to reset the node.
Table represents some typical problems that you may encounter while working with
the Development Kit and possible solutions.
Table 14. Typical problems and solutions
Problem
The board does not
indicate its activity with
LEDs.
The board does not
respond to outer
commands (in case of
external antenna)
In effort to connect
several boards to the
same PC their detection
fails due to ID
recognition conflict.
WSN Monitor fails to
start.
No node is shown on
the Topology Pane in
the WSN Monitor
Solution
Make sure that either WSNDemo image or Hardware
Test image is loaded. For SerialNet, the LED status is
controlled by AT-commands.
Make sure the external antenna is not broken and it is
properly connected to the board.
Detect ID for any single connected board using the
USBView.exe utility from Silicon Laboratories.
It can be downloaded from http://www.silabs.com/

Microcontrollers/USB/en/USBXpress.htm
You can use the CP210xSetIDs.exe utility from Silicon
Laboratories which is included in AN144SW. It is
described at http://www.silabs.com/public/documents/
tpub_doc/anote/Microcontrollers/Interface/en/an144.pdf
and it can be downloaded from
http://www.silabs.com/public/documents/software_doc/
othersoftware/Microcontrollers/Interface/en/an144sw.zip.
Make sure Java machine is properly installed on your
PC. Java Runtime Environment installation program can
be found in ./Third Party Software/ directory as
jre-6u6-windows-i586-p.exe file (see Appendix
Section 10.7)
Check if the WSN Monitor uses proper COM port and if
not, change it and restart the program.
