Dear All,

	How to detect buzzer tone (of frequency 4kHz) on mica sensor
	boards...

	I used Mic.readToneDetector() in a while loop, it is always
	returning '0'(tone detected) even though buzzer of the other node
	is silent.

	if I use same command in side the IF condition it is always it is
	returing non zero value...

	I also tried with Attr-rawtone.......

	please let me know how can i detect rawtones...

		I am using MTS 300CA sensor Board...

Thanking you,
Manjunath
