Mostly people use Echo 10/20 Soil Moisture Sensors from Decagon
http://www.decagon.com/ag_research/soil/ec20.php
with Mica2 motes and MDA300 sensor boards because the code is
already available.
We just purchased Echo 20 and we could get the readings successfully from
telosb motes. But since there
I think you are talking about asymmetric link. Additional experiment on
swapping transmitter/receiver should be conducted to validate such
assumption (under particular circumstances).

Hello everyone,
We want to remove the battery casing on an Iris mote and supply 3V DC
power directly to the mote from other electronics. I can see a white
PCB mounted two pin connector on the mote with a trace leading to one
of the battery connections. I was wondering if someone can confirm
that

I would second what Aurelien has already said. Having source packages
would be definitely beneficial in supporting larger number of
distributions that generally rely on similar package management but
then also have quirks that make it difficult to install binary

I read the tinyos programming guide, but didn't understand exactly
this part of manual(page 41) :

not promise that the atomic block won't be preempted. Even with atomic

Hi Romain!
Here are details:
In Makefile I've commented:
#CFLAGS += -DCC2420_NO_ACKNOWLEDGEMENTS
Otherwise the things are much worse.
The application is derived from BaseStation, changed so that the once
sent message (received throw serial from PC) arrives the TARGET comes
back TO SOURCE and
Altering the default value 29 of the constant TOSH_DATA_LENGTH in AM.h file
(it is also possible, and recommended, to do this in the Makefile of the
application directory), I verified that it is possible to change the payload
data of our TOS message.
I made some tests and found the exact limits:
Can you just hook up the power to the pads where the battery holder attached?

If you want to check the channel *before* sending a packet, you can sample
the CCA pin directly. This GeneralIO is provided by HplCC2420PinsC.
The code you're looking at here actually sends a packet, if the channel is
immediately found to be clear. If you're not doing so already, you must

I want to change the default IEEE 802.15.4 symbol-to-chip mapping (as
described on page 24 of the datasheet of 2.4 GHz IEEE 802.15.4 /

that?

Clear channel assessments are performed automatically by the CC2420 radio

In the CC2420 radio, a CSMA strategy is implemented where initial and

transmissions
Hi Poonam,
If you are just starting, I would suggest you go for MultiHop Protocols in
TinyOS 2,
which are CTP(Collection Tree Protocol) and LQI(improved version of
MultiHopLQI in tinyos 1). These are made better by the developers based on
their experience with problems in
