Who could tell me that is why??
Probably there is some part of your code which is executing when it

Hello,
I am using TelosB motes with Hamamatsu's PAR and TSR light sensors. I
am monitoring the readings of the PAR sensor and I have noticed the
following, using constant light intensity:

Hello all,
I have been creating a couple of scripts on bash to help me deal with
the connection and disconnection of motes to the computer
automatically.
I want to open N connections to N motes using N SerialForwarders. To
do this, I have a while loop which reads the USB addresses from a
lookup
Jose,
To connect to multiple motes you would write something along the lines of:

Thanks a lot for that. I had been trying to use these phoenix sources
a while ago but didn't get to make my program work.
This means that when I start a java program that wants to talk to
different motes

Sure -- I could see a solution where you use some method to
synchronize all motes to a common time base (perhaps using any of the
proposed radio time sync protocols) and then you use USB to transmit
messages of the form: at time X do Y,where time X
2006/8/24, Robert Szewczyk [EMAIL PROTECTED]:
But this would also mean that it is not possible to send a message to
_all_ motes simultaneously, right? This would be a big problem...
That's correct. Simultaneous transmission to all motes over usb would
be difficult over a point to point link
Well, the MoteIV RPM is indeed not installing properly. I am getting

Hi all...
I have come with an idea of the origin of the faulty behaviour of my
experiment...
To simplify I will illustrate it with two dimmers: they are connected to
the wall sockets and to the motes, and the motes are connected per USB
to a HUB which is also connected to a wall socket and to
Joe,
yeah, my configuration is as follows: I have 10 motes, five of them
are connected to the inverter/amplifier/dimmer group. This means I
need three hubs, each of them with four usb outputs. For this
experiment only these 5 motes are connected, and my hub configuration
is as follows:

Dear all,
I have been working on a time sync protocol between the pc and the

would like to improve things on the motes.
My test for the time-sync consists of running the sync protocol every

Janos,
thanks for your quick answer. I noticed, as you said, that a lot of my
problems might be related to the PC/motes interaction. However, I fail
to understand what you mean with tasks/interruptions. Are you suggesting
I should create interruptions (async command or event) which would be

Alternatively, I think you can use LocalTimeMicroC too to get the mote

Hi all,
Once again, I have a quick question regarding Java and message
management.
When classes which require receiving messages from the motes are
programmed, usually all those classes are based on MessageListener. In
this way, we have the following method when we receive a message:
