Hi again guys,
I was trying to do this patch on an Xubuntu 11.10 of one of my group
members and after I do the ant jar command it says that cannot find the
Listen class and so on for the other java programs.
I think is a nesC problem, but i can't find what.
The output of the ant jar command is
Hi Luís,
These are interesting findings. I don't think it is a problem related to
Java as a language. It appears to me that the microcontroller is reset
as soon as the serial port is opened. Maybe the Java programs that you
have tried set some handshaking lines that cause a reset.
If you look
Hi Urs,
Thanks for your aswer. So if Java programs work that way, there is nothing I
can do to make it work do I?
Well I could make some C/C++ program to do what I want.

Hi Urs,
You're right.
I mesaurd the voltage on the reset button: it's about 3.3V when it's
unpressed, and 0V if pressed. But after I connect to the mote with
Listen, the voltage is always 0V, which means, it's in reset state.
The mote only exit the reset state if I unplug/replug it, or reset it
Hi Luís,
Hi Andris,
As Andris pointed out, if you could control the RTS/DTS lines, you
should be able to solve this. Actually, this is not a Java problem, as
Java doesn't have support for the serial port. Java uses a JNI (Java
Native Interface) library written in C and provided by TinyOS to
Hi Guys,
Urs, it's not always working in c, I couldn't use it with cutecom.
But since I worked with the JNI libraries recently, I checked what
should be changed, and it was really easy, check the attached patch (I
did the change on the svn version). You can try it with:
cd $TOSROOT/sdk/java
Hi Urs,
I tried to create a serial forward using the cpp program that comes with
tinyos (I don't know how to compile the C program that comes with it too)
and I have the same problem. It turn off the mote and can't connect. After
study the code, I found out it get stuck in writteBuffer.dequeue().
Hi András,
I tried out your patch but it didn't work. I test a few combinations of the
RTS DTS state and none of them work. Did it work for you?
What do you mean with ant jar? I don't understand that line.
Thanks for your help

Yes, it worked for me (I also tried all the combinations, only this one worked).
ant jar: It regenerates the tinyos.jar file. Apache ant is similar to
GNU Make, but it's designed for java. You will need ant and javac to
regenerate the jar file (and mig and ncg, which are part of nesc and

Hi Luís,
The FTDI drivers actually only create one serial port (the others were
probably thinking of the X-Bow MIB520 programming boards for the
Mica-series of motes).
The telosa platform is distinct from the telosb / tmote platform. If you
really have a telosa platform, maybe you could try

No.
I'm not sure what the other guy is using and why he is saying that an FTDI
interface results in two USB devs in the /dev/ttyUSB* tree but that is
Hi Luís,
I just had a look. It appears that telosa, telosb and tmote all use the
same baud rate, and that the platform name for telosa on TinyOS is just
telos (not tmote).
TelosA and TelosB/Tmote are similar, but not identical. It is entirely
possible that if you compile your programs for the
Hi Urs,
I am already using the telos platform. I post a command with tmote because I
read in some other question to try that way, and it doesn't make any
difference. I am trying to communicate with the mote using the
apps/tests/TestLed/Multiled program and I got this outputs:
MAKE TELOS:
mkdir
Hi Luis,
I had similar problems with telosa motes, and I don't know what caused
the problem, or how to resolve it, but I found a workaround.
Unofrtunatly it only worked on windows (xp)+cygwin:
Before opening the serial port with the tinyos java apps, I opened it
with rxtx

Ok I will try to open the usb port with rxtx to see what happen..can you

Sorry, those codes are lost, but it's easy to simplify an rxtx
example. Acutally, you only need to list the available serial ports,
since it tries to open them. And again: it only worked on windows.

Hi guys,
Following that tip Bíró gave, i found a little program that uses rxtx to
find and open the usb port. When I run the program it find the door and my

I'm starting a project at my school using telosa. I'm trying to do the

resynchronizing message and

please show what command did you executed.

Hi Rafael,
well when I run motelist i have:
Reference Device Description
-- -
M4MWCK4F /dev/ttyUSB0 Moteiv Telos (Rev A 2004-04-27)
Then i run:
java net.tinyos.tools.Listen -comm serial@/dev/ttyUSB0:tmote
Try
java net.tinyos.tools.Listen -comm serial@/dev/ttyUSB1:tmote
instead.
FTDI creates 2 USB ports, one for reading and one for writing!

Sorry but here only ttyUSB0 exist. I have no USB1.
By the way i'm using archlinux but i don't think that is the problem.
