NTP server.
Hi Mike
We could use your piece of code to stream the serial data once streaming is
enabled through the GUI.
Is there any python script to start streaming (sending the command to begin
streaming to Shimmer)?
Thanks
Ram

I'm not really sure what you are looking for in (1). Are you talking about
streaming the data or logging it? It might be helpful to take a look at the
SimpleAccel application
(http://tinyos.cvs.sourceforge.net/viewvc/tinyos/tinyos-2.x-contrib/shimmer/apps/SimpleAccel/)
and the associated python script in the same folder.
There is an NTP implementation for the shimmer available in TinyOS version 1.
Take a look at TestNTP
(http://tinyos.cvs.sourceforge.net/viewvc/tinyos/tinyos-1.x/contrib/handhelds/swtest/TestNTP/).
However, I've never used this myself, so I'm not entirely sure how it works
other than it uses the microIP stack for communication (take a look at the
video here to see how to get this stack up and running:
http://www.shimmer-research.com/research-2/microip-example). Also, you should
know that version 1 of TinyOS is deprecated and shouldn't really be used for
new projects. So you could either port this implementation to tinyos version 2
or else run NTP on the basestation (laptop or PC probably) and send the time to
the shimmers any way you like.
