Hello
I think if it is logical to use LPL and PacketLink interface at the same time.
As far as I know right now, using only LPL the message will be sent several
times during the set time in the command setRxSleepInterval. In execution, what
is the difference using the following two code
I am sorry, I forgot to put the code:
1)
call PacketLink.setRetries(PaqueteDatos, 10);
call PacketLink.setRetryDelay(PaqueteDatos, 100);

Hi,
I'm working on an application that implements a localization algorithm that
uses RSSI values to determine the distance.
I did a little experiment to see the average value of RSSI for different
distances, and the resolution of the average values that I got isn't good
enough for me.
Is there a
In my opinion, the RSSI readings are quite susceptible to various
environmental conditions. Conducting more runs may help.
How many runs per distance have you done?
I think you may compute the median and compared it to the average.

You mean the RSSI values will vary if the environment varies? In that case,
conducting experiments in a typical indoor environment where not too many
people are walking around will show consistent RSSI values?

I can't 100% say that. An indoor environment may have several sources
affecting signal propagation and attenuation behaviours.

Hi,
Please I whould like to know if I had truly undestand :
basically CC2420radio stack uses CSMA to acces to the channel but if we active
Low Power Listening then it uses TDMA .
Is it true?
Best regards,
Fun

Could you point out any study/paper that describes these effects?

As I'm quite busy with my research, you should google by yourself.

Hi All:
I installed TinyOS 2.0 to cygwin. When I tried to check the
environment with tos-check-env. I got error message as following:
-- WARNING: No flex in current path.
-- WARNING: No bison in current path.
And I tried to ignore it and compile Blink by make micaz sim. I got
error message as
Hi,
I am using oscilloscope but I changed it because I only want to show one
channel (temperature). In the oscope graph the scale is not in Celsius, so I
want to introduce this formulae:
temperature = -39.60 + 0.01 * SOt
where SOt is the raw output of the sensor
so my question is in what file of

Hi,
I am a college student and I am new to TinyOS. I am current using version 2.x
of TinyOS. I wrote a program which sends radio packets from one telosb mote to
another. However, the second part of my project is to forward the received
packet to another microcontroller through UART.
I read

I have several motes collecting data and communicating through the provided
collection and dissemination protocol implementations in the net library.
However, the battery life on these motes is quite poor; they only last for
around a week and half. I attempted to implement low power
there really is no point in changing anything but the scale on the
'scope. I have never read through the code enough to know where that
is.

Also if I recall correctly nesC 1.3 and TOSSIM are known to not play well
together at the moment. So probably this is not the time to upgrade that
