[Tinyos-help] Time-delay between Matlab and Mica2dot

[Daniel Widyanto]

Hi,

I'm not sure whether TinyOS really suitable for your application. 
The WSN in TinyOS is used to monitoring vast area, long period 
(1min - 1day/sampling), and long term (6 months until years 
without replacing the battery). 200 ms probably is very fast (though 
it's not the fastest one).

Anyway, I think you can reduce the delay, by reducing the Matlab's 
serial buffer. 

Regards,
