Hi Phil,
Sorry for not having replied before, I've been away a couple of weeks.
When there is a tone, thee LED toggles too, that's why I don't know what's
happening.
Thank you very much for your help.
Regards,
Jorge

I'd email the folks who wrote the drivers; I'm not sure they all
ready tinyos-help regularly. It looks like the driver is just
checking an interrupt line when it does this test. Looking at the
code, it seems like it just returns 1 when the line is high and 0
when it's low... which suggests that the documentation of the return
value is incorrect. Does the LED toggle when there is a tone, or does
it stop toggling?
Phil
