Hello,
We want to measure time between two events using timestamps in
microseconds.(micaz motes)
1) receiving time of a radio packet
2) beep listening,by calling Mic.readToneDetector() command.
how can i get the timestamps.
thankyou for your assistance
warm regards
Umesh
I forget the exact number - it's somewhere around 241 bytes payload for the
mica2/mica2dot. The micaz has about a 110 to 113 byte payload max.
In noisy (real world) environments, it's best to keep the packet size lower
to avoid major packet/data loss, or having to retransmit.

Hi,
Thanks to all who replied earlier to my question about modifying the
CC2420 MAC. After reading the relevant parts of the data sheet, most of
my questions have been answered. I am still concerned about one thing. I
was interested in sending short impulses about one CC2420_SYMBOL_UNIT

Hi, what's the upper limit for MSG_SIZE, say for mica2? Thanks,

Moteiv also has documentation on the items we changed and updated
schematics in our datasheet, all freely available.

What about the design files for the tmote? Any chance of getting them?

The design is based off the Mica design, but was done by Crossbow in
collaboration with UCB. When the design was finalized, Crossbow
started to produce it, but UCB never got the source files to the
design (unfortunately). Someone from Xbow should chime in, but I
believe that this is part of their
The default baud rate is exactly the same, 57600.
In fact, you can increase the baud rate on tmote much higher than on
the micaz. Please see the following document:

Hi Brett,
You might want to take a look at the following paper and similar
study:
A. Mohan, W. Hong, D. Gay, P. Buonadonna, T. Doeppner, and
A. Mainwaring. End-to-End Performance Characterization of Sensornet
Multihop Routing. In IEEE ICPS, 2005.
If you want to discuss more, send me an email.
Title: Message
It seems that the
uart baud rate on the micaz's (57600) is much faster than the tmotes - I'm
not sure what the tmote's baud rate is. But I do notice a
significant different between the UART speeds on the two motes. Is there a
way to jack up the baud rate on these tmote's?
Try to check the .nc code of the Pong application (just search in the
archive), you might find it helpful.
hope this helps
Costa

As for the compiler errors, I don't know. Are you sure your MAKERULES
