[Tinyos-help] 'Times' returned by RadioTimeStamping.receivedSFD() and RadioTimeStamping.transmittedSFD()

[Ittipong Khemapech]

Hi,

I've been stuck with the 'times' returned by RadioTimeStamping.receivedSFD()
and RadioTimeStamping.transmittedSFD(). In my application, the base sends a
packet to its source. The source waits for 1 second (32,768 ticks) and then
sends a packet back to the base station.

The receivedSFD provides 'time' but the one from transmittedSFD is always 0
(zero).

I tried an Alarm to give current time that can be used by both event. It
still doesn't work.

I was wondering if anybody experienced this.

Any suggestions would be great.

Best Wishes,
Ittipong
