Re: [Tinyos-help] serial forwarder error

[roberto pagliari]

Apologies for the delay in my answer, I've been working on other projects
recently.

I can run the listener app now. Basestation is connected to ttyUSB0 in my
case. However I do not see the packet on my computer. Here is what I do


bob@bob-laptop:/opt/tinyos-2.1.1/apps/BaseStation$ export MOTECOM=serial@
/dev/ttyUSB0:micaz
bob@bob-laptop:/opt/tinyos-2.1.1/apps/BaseStation$ java
net.tinyos.tools.Listen
serial@/dev/ttyUSB0:57600: resynchronising


and then nothing shows up (the other mote has BlinkToRadio on it, from the
website).



Thanks

[Tinyos-help] Serial Forwarder died!

[Geo Gkolfin]

Hello everyone!
I am running the BlinkToRadio application (as described in the tinyos
tutorial) on an iris mote, connected to /dev/ttyUSB0. From /BlinkToRadio
directory I create a serial Forwarder:

*java net.tinyos.sf.SerialForwarder -comm serial@/dev/ttyUSB1:iris *

The first time I execute the command the window shown in the tutorial pops
up and counts packets normally, but the number of clients is set to zero
(shouldn't it be 1?). I quit and try to create a serial Forwarder again
using the exact same command, yet what I get to the serial forwarder window
is a periodically repeated message:

*Could not open /dev/ttyUSB1:TOSComm JNI Library Runtime error:open:No such
file or directory.*
*serial@/dev/ttyUSB1:57600 died - restarting*

I try to a different port:

*java net.tinyos.sf.SerialForwarder -port 9003 -comm serial@
/dev/ttyUSB1:iris*

and I get the exact same result (with the number of clients always set to
0).

Can you tell what the problem is?
Thank you all in advance,
Georgia

Re: [Tinyos-help] serial forwarder error

[Michael Schippling]

Check your CLASSPATH and the contents of the java tools or jar.
You are trying to run the "Listen" program -- which has nothing
to do with SerialForwarder or Oscilloscope -- and the main class
is not being found in your path.

Would be better to try the whole list: (you should put these at the end of
~/.bash_profile, beware the paths might be different in your case)

export TOSROOT="/opt/tinyos-2.x"
export TOSDIR="$TOSROOT/tos"
export CLASSPATH=".;C:/cygwin/opt/tinyos-2.x/support/sdk/java"
export
CLASSPATH="$CLASSPATH;C:\cygwin\opt\tinyos-2.x\support\sdk\java\tinyos.jar;."
export MAKERULES="$TOSROOT/support/make/Makerules"
export PATH="/opt/msp430/bin:/opt/jflashmm:$PATH"

Did you try this, it works for me

export CLASSPATH=$TOSROOT/support/sdk/java/tinyos.jar:.

also you should use USB1 not USB0 for listening. and ? think you forget : 
before micaz

 java net.tinyos.tools.Listen -comm serial@/dev/ttyUSB1:micaz

try this maybe it will work

Re: [Tinyos-help] Serial Forwarder help for a newbie

[Eric Decker]

Here is what I did to find the information you probably are looking for:

I went to TinyOS Docs Wiki .
Over on the left side is a search box.I searched for "serialforwarder".

The first 2 entries on the search page have what you are probably looking
for.  You most likely want to look at
the TOS 2.1.1 page because that is the current documentation for the latest
release.

[Tinyos-help] serial forwarder "bad packet" vs "bit CRC" in CC2420

[Correo de Wacka]

Hi all,

My last doubt is that, the "bad packet" that appears in the serial
forwarder has to match with the bit CRC (wrong) of the CC24020 (MicaZ)?I've
tested it, but I receive more wrongs CRC bits, that "bad packets"
appears in the serial forwarder window.

thanks for your time

David

You can try to copy getenv.dll and toscomm.dll from C:\cygwin\lib\tinyos to
your JRE's bin or lib directory, or to C:\Windows\System32.

[Tinyos-help] serial forwarder

[Yasser Zahedi]

Hi all,
I was using the serial forwarder to listen to the sensor and it was working
well, but suddenly when I write the command  : (java
net.tinyos.sf.SerialForwarder) the tinyos gives me the following error:

(The toscomm JNI library was not found.
Check that your tinyos-tools package is installed and try
rerunning tos-install-jni.
Aborting. )

So, can anyone help me with this... Also I think the other commands that
depend on java like (listen) give me errors.

Thank you

[Tinyos-help] Serial forwarder and tossim-serial

[Yusnaidi Md Yusof]

Hi All,

I got a problem to use the tossim-serial in the SerialForwarder tool. I
intend to view packets reception at Node 0 (root of the CTP) in the MViz
program. I confused how to use the SerialForwarder with the tossim-serial as
a source?, since I couldn't find any tutorial on it even in the 'Mote-PC
serial communication and serial forwarder'  and the 'TOSSIM' tutorials of
the TinyOS Tutorials.

I have issued several command such as:
$java net.tinyos.sf.SerialForwarder -comm tossim-serial
$java net.tinyos.sf.SerialForwarder -comm tossim-ra...@hostname
$java net.tinyos.sf.SerialForwarder -comm tossim-ser...@hostname
$java net.tinyos.sf.SerialForwarder -comm tossim-ser...@hostname:9002

but all seems failed with the following error messages:

Couldn't instantiate tossim packet source
Did you compile tossim?
Serial Forwarder Exited Normally


In addition, I tried this combination:
1st: Running the MViz application with commands: $make micaz sim, $python
mviz.py (A script of my own created with 1 seconds sim time)
2nd: While MViz simulation running, I ran the serial forwarder tool: $java
net.tinyos.sf.SerialForwarder -comm s...@localhost:9002
3rd: While both the MViz application is running and the SerialForwarder tool
also running (1st and 2nd steps above): I issue command: $ tos-mviz -comm
s...@localhost:9002 MVizMsg

What I got were an MViz window opened but with no packets reading, and the
sf window keep on listening the 9002 port but also with zero 'Pckts read'
and 'Pckts wrttn'...

I am so confused what port I need to open, or what is the proper steps to do
in order to view the data reception on Node 0 (root) in MViz?

Please help me...

thanks

Yusnaidi

[Tinyos-help] serial forwarder

[John Khalil]

 

Hi,

I am trying to use serial forwarder and I typed the command 

 

$ java net.tinyos.sf.SerialForwarder

And I got

 

The toscomm JNI library was not found.

Check that your tinyos-tools package is installed and try

rerunning tos-install-jni.

Aborting.

 

I tried 

 

$ tos-install-jni

 

 And I got it

Installing 32-bit Java JNI code in /cygdrive/c/Program
Files/Java/jdk1.6.0_17/jr

e/bin ...

install: cannot stat `/usr/lib/tinyos/*-32.dll': No such file or directory

 

Then I changed tosscom.dll file name to tosscom-32.dll and retry 

 

$ tos-install-jni

 

I got 

 

Installing 32-bit Java JNI code in /cygdrive/c/Program
Files/Java/jdk1.6.0_17/jr

e/bin ...

done.

 

However when I try

 

java net.tinyos.sf.SerialForwarder

 

I got the same error.

 

Any recommendation?

 

Thanks

John

Re: [Tinyos-help] Serial Forwarder

[Arik Sapojnik]

Nikos,

I don't entirely agree with you:

   1. "The BaseStation app will forward anything..." - but with what AM type
   to what destination address?
   2. I added printf in UartReceive.receive, and then sent the following:
   "0x01" - Nothing happened
   "0xFF" - the print worked
   I think that the reason is the first byte is the destination address
   (since the UART works with AM layer).
   3. I want to work with C and I couldn't find any examples working with
   MIG (only Java examples).

Re: [Tinyos-help] Serial Forwarder

[Nikos Batalas]

Hi Arik,

I don't think you need to worry about the message format on the level of 
either the BaseStation or the SerialForwarder.

The BaseStation app will forward anything it receives to serial 
forwarder, and so will the latter to whoever is connected with it.

It should be your own application's responsibility (using the java sdk 
and mig-generated classes, for example) to make sense of what the bytes 
in the payload mean.

Best Regards,
Nikos

Hi,

I'd like to use Serial Forwarder + Base Station application in order to
connect my PC with my motes' network.
What should be the format of the message I send to SF?
It seems that it supposes to be message_t, but if so, does it mean I have to
implement the whole Packet interface? It can't be true :)

Re: [Tinyos-help] serial forwarder and hyper terminal

[Michael Schippling]

...cc'ing back to the help list...

We just had a discussion of why you need to put a platform
name in your MOTECOM instead of a baudrate. W/o the name the
message format defaults to the original mica2 AM.h structure,
search back on this list a week or two.

ListenRaw is not so smart about ports so good luck with the -p thing.
Don't know why parity is false, although when I do it on Widows:
Opening port COM3
  baud rate: 57600
  data bits: 8
  stop bits: 1
  parity:0
I assume 0 is false, so I guess it's OK.

But the point was, do you get any data when you do ListenRaw?
If not there is something else strange going on.

Re: [Tinyos-help] serial forwarder and hyper terminal

[Michael Schippling]

Make sure you are using a MOTECOM setting that matches the
baudrate and AM message header format that your node uses.
Also try the ListenRaw program to see exactly what you are
getting. Hyperterminal probably tries to interpret everything
as ASCII whereas the message is binary.

[farooq_s]

hi,

when i connect my custom node with COM1, I can receive data in hyperterminal
but cannot do so in tinyos. I have tried both the java
net.tinyos.tools.Listen and the serialforwarder but both display
resynchronizing and then nothing happens. What can i do to enable
communication using the Listen command in tinyos?

I will be waiting for your replies!

Re: [Tinyos-help] Serial forwarder, C compilation => integration with external 9script) programs

I've used an open source C serial listener/writer. The code is in attachement.

 

Hope this helps out.

Subject: [Tinyos-help] Serial forwarder, C compilation => integration with 
external 9script) programs

Finally, I integrated the SerialForwarder option (C version, Debian OS, TinyOS 
2.1) with my base-station programs. For this, I only had to copy the T2 stuff 
to a directory and install a small JVM at the device for C compilation 
purposes. Now, I don't actually need the T2 stuff I copied to the device, 
except the C compiled codes related to the sf directory.  Also, I don't need to 
run the JVM anymore and my small device CPU capabilities thank for this 
resources savings.

I am using this solution to integrate multiple WSNs (MICA2, MICAz, TelosB, 
Iris, Imote2). I only tested for MICAz, but I think I will have no problems 
with the other platforms. I also need to have this solution for SunSPOT.

2 questions for the group:

1) Does anyone have any experience with a simple serial port listener software 
(C)? It is not for the TinyOS environment. Actually, I would like to use this 
capture program for the SunSPOT solution. Using the linux minicom software, I 
can also hear the messages from the SunSPOTs, but I need a C program to 
integrate it in my bash scripts.

2) Using the SF stuff (in my case, I am using sf and sflisten programs), the 
raw data is fine for me, because I can easily get my payload data from the T2 
messages. However, the integration of these programs with my linux scripts is 
not easy and I have 800-1100 ms of latency with the actual solution. Part of 
this latency is actually caused by the serial port speed bottleneck, but part 
is caused by the way I am solving the integration with the SF programs. Does 
anyone have any modified SF programs aiming integrating with external (script) 
programs?

Any suggestion is welcome !

MS: I did not understand your question about the radio reception. Actually, I 
developed my own T2 software to gather debugging/sensing data from each WSN. In 
a specific WSN, the nodes debugging/sensing data are transferred to their 
specific "WSN gateway", a mote that is USB-connected to the Linux-device I 
mentioned. This device has many "WSN gateways" attached to it. The software at 
this linux device transfers all messages, from all WSNs, to a PC-based server.

Re: [Tinyos-help] Serial Forwarder

[Patrick Brady]

Hi folks,

I'm a final year engineering student and for my project I'm trying to
develop a system using sensor networks.
I have 2 tmoteinvent sensors programmed with the oscilloscope application
and I'm trying to get the raw data from the sensors
into a Java program I'm writing in Eclipse.
I'm using the serial forwarder but when I try to connect I get the following
error message:


s...@localhost:9001 died - exiting (java.io.IOException: protocol error)

The code I'm using to connect is as follows:

PhoenixSource reader = BuildSource.makePhoenix( BuildSource.makeSF(
"localhost" , 9001 ), null );
reader.start( );
MoteIF moteif = new MoteIF( reader );
moteif.registerListener( new OscopeMsg( ) , new MessageListener( ) {
   public void messageReceived ( int dest , Message rawMsg ) {
  System.out.println( "Received." );
   }
} );

I'm pretty sure this code is right, but I don't understand the "protocol
error".
Any help is appreciated.

Thanks,
Pat.

  I'm trying to use serial forwarder in tinyos supported by C
the format is sf   
in Java we invoke the serial forwarder by java net.tinyos.sf.SerialForwarder
-comm [EMAIL PROTECTED]:2390

How dis can be done in C?der's no hardware..just simulating basemote in
avrora...
Kindly help..

with warm regards

[Tinyos-help] Serial Forwarder Application

[Rafael Aguilar Velez]

Hello to everybody,

 

I am using the application Serial Forwarder. In the main screen appear a box 
that says: "Control Panel". Does anyone know what is this and how to use it?

 

Thank you very much

 

Rafael

I don’t know how set up MOTECOM environment variable to IRIS motes, I don’t
find it on documentation. I’m using this command:

 

java net.tinyos.tools.Listen

 

And I get this error:

 

Error on [EMAIL PROTECTED]:9002: java.net.ConnectException: Connection refused

 

And:

 

java net.tinyos.sf.SerialForwarder -comm

And I get “Invalid source serial@/dev/ttyUSB0:iris”

 

Thanks,

Listen and SerialForwarder should work with an IRIS setup. Did you set up
the MOTECOM environment variable correctly? What command line parameters did
you use with these Java apps?

In particular, the ftdi driver seems to be really bad about

Re: [Tinyos-help] Serial forwarder suddenly corrupted then ... could not open port: (5, 'CreateFile', 'Access is denied.')

[Michael Schippling]

Probably something crashed but still has the serial port open,
it may be a zombie process or the kernel itself. First look through
your process list for possible culprits and then try a reboot
to clear things up.

Re: [Tinyos-help] Serial forwarder

[Michael Schippling]

I'm not very familiar with SF, but if you use the 'standard' MoteIF
code to send you should have no problem with handshake or CRC. To
create your own you'll probably have to reverse engineer the existing
code starting from Packetizer.java. I also don't know how you received
messages at a re-Mote without setting the CRC to start with...

Re: [Tinyos-help] Serial forwarder

[Michael Schippling]

How are you sending it? If you're using MoteIF or an equivalent
it should _just work_(TM). But I think there is a bit of extra
handshaking done on the net port interface if you are trying
to roll your own. Also it looks like your CRC hasn't been calculated.

Re: [Tinyos-help] Serial Forwarder

[Michael Schippling]

As far as I know moteIF is pretty much it in Java. You can use it
to connect directly to the serial port on the MIBs, etal. If you
want to slim things down, look at Packetizer.java where most of
the rubber meets the road. Also there are examples in C in the tools
tree, and C# seems to be possible if you search this list.

Hello,

I want to send a message to the MicaZ - I've my PC connected to Mote's serial

Serial Forwarder should I use?

RE: [Tinyos-help] Serial Forwarder and Listen

[Ben Buckner]

The short answer is no, there's no CR/LF. However, the packets do come with
a frame, and the frame has an escape rule that can result in escape
characters being inserted. That's probably why you unexpectedly get changing
packet lengths. The "right" way to pick packets out of the stream is to look
for the framing bytes, 0x7E, which come at the beginning and the end of the
packet.

RE: [Tinyos-help] Serial Forwarder Problem

[Darren Bishop]

I am currently developing a mote testbed management software.

Here are some hints:

1. Use udev to detect when motes are attached or detached.
2. Through udev you can set up an instance of serial forwarder to listen to
that mote - local address is taken to mean the serial/COM port.
3. For each instance of sf, use a different TCP port; devise some mapping
scheme for consistency - if you have multiple machines, perhaps use some
unique part of the machine/host name. In other words, use a global naming
scheme.

If you are not on Linux i.e. you are using Windows, Google for a udev
equivalent, or poke around 'Control Panel'.

Best regards,

For the case of using a single mote with TOSBase which forwards messages
it is clear. But, say we got two motes connected per USB to the computer.
We would need two instances of SerialForwarder, each associated to one of
the motes, and if a program on the computer wants to communicate with one
of the motes, it would have to know which SerialFowarder to connect to.

How would I have to do that?

And going a bit further. The ideal case would be to have a program which
automatically checks USB ports, gets the mote address of each mote
connected and creates a SerialForwarder association with each mote, so
that if a program wants to send a message to a mote, it only needs to know
its local address. I am sure something similar already exists. I would
like to know is it done.

Thanks,

- J.

Re: [Tinyos-help] Serial Forwarder Problem

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 is sufficiently far
in the future.

Mmmm... Perhaps a better solution would be to use both USB and
radio... I have used SerialForwarder Multiplexer but I am not getting
very good results and I am thinking that using multiple instances of
SerialForwarder and mapping might be more work but in the end the
computer-mote communication should be more reliable this way...

That's correct.  Simultaneous transmission to all motes over usb would
be difficult over a point to point link such as USB .  USB host
schedules transmissions to individual endpoints on a 1 ms granularity,
and depending on the precise timing of requests you may observe as
much as 2 ms between requests.   It sounds like if you want  motes to

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 through different SerialForwarders, it needs also
needs to read from a table for each mote id in which USB port it is
connected.

What's more, if I want to send a message to mote "100", for example, using

mote_if_of_mote100.send(100, message);

and

mote_if_of_mote100.send(TOS_BCAST_ADDRESS, message);

will give the same result.


Right.


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 such as USB .  USB host
schedules transmissions to individual endpoints on a 1 ms granularity,
and depending on the precise timing of requests you may observe as
much as 2 ms between requests.   It sounds like if you want  motes to
receive a message simultaneously, a radio broadcast channel may be
appropriate.

Well, I was thinking more along the lines of using USB if only one

 mote_if1 = new MoteIF(BuildSource.makePhoenix(sfString1, (Messenger) null);
 mote_if1.registerListener(new MsgType(), this);
 mote_if1.start();

  // connect to the other Tmote connected to the local machine, e.g.
[EMAIL PROTECTED]:tmote
 mote_if2 = new MoteIF(BuildSource.makePhoenix(sfString2, (Messenger) null);
 // need to register the listeners for every MoteIF started

Shane,

I think this approach is the logical and simpler solution to this issue.
However, my problem is that I am using USB: My motes are connected to a
number of USB Hubs which are connected to the computer (A Laptop). Every
time I connect the computer to this testbed, the USB port number of a
given mote is different.

Now that I think about it, I guess I could use the mote identifier that
appears when calling motelist and build a table according to that...

Any suggestions regarding a scripting language? (I haven't really made
many scripts, I just modify them :))

Second question: Suppose I have two motes and two instances of
SerialForwarder running, one for each mote. If I have a program which
wants to communicate with one of the motes, how does the program know
which of the SerialForwarders to use? For the case of a single
SerialForwarder, I have always done:

  mote_if = new MoteIF((Messenger)null);
  mote_if.registerListener(new MsgType(), this);

  mote_if.start();

  mote_if.send(mote_id, message);

But I'd guess that if I have multiple instances of SerialFowarder it
should be done in some other way.

Re: [Tinyos-help] Serial Forwarder Problem

[Shane B. Eisenman]

jose,

you certainly //could// modify a mote-side component in the UART stack to 
implement a control message that returns the TOS_LOCAL_ADDRESS of a mote 
connected to particular MIB600, and then modify serial forwarder to 
implement the PC-side of that same query mechanism.


however, the simpler approach (though less transparent) is to define a 
mapping of moteID to SF exported TCP port in a file on your PC, and use a 
script to scroll through that file and launch N sessions of SF. I've done 
this for a testbed of 35 mica2/MIBs i've used at Columbia and it is 
convenient for me. I've used an easy-to-remember mapping (e.g., moteID 1 
is mounted on the MIB600 whose associated SF instance exports port 9001, 
etc.) so that i don't have to ever look at that mapping file.


I even went the extra step of assigning IPs to the MIB600s in such a way 
that the subnet address matches the moteID (e.g., modeID 1 is mounted to 
the MIB having address x.x.x.1 whose associated SF instance exports port 
9001). This makes writing shell scripts for "one-click" reprogramming of 
all motes, "one-click" SF restart (after Java occassionally crashes), etc. 
really straightforward to write.


the MIST testbed at MIT has a 55+mica2/MIB setup. i think they use MoteLab 
to manage that testbed; one of them might chime in with details on that.

For the case of using a single mote with TOSBase which forwards messages
it is clear. But, say we got two motes connected per USB to the computer.
We would need two instances of SerialForwarder, each associated to one of
the motes, and if a program on the computer wants to communicate with one
of the motes, it would have to know which SerialFowarder to connect to.

How would I have to do that?

And going a bit further. The ideal case would be to have a program which
automatically checks USB ports, gets the mote address of each mote
connected and creates a SerialForwarder association with each mote, so
that if a program wants to send a message to a mote, it only needs to know
its local address. I am sure something similar already exists. I would
like to know is it done.

TOSMsg byte order is little-endian,
a byte stream like 11 22 33 44 is two short ints with values 0x2211 0x4433

[Tinyos-help] Serial Forwarder vs Listen

[Dattatraya Gokhale]

Hi..When we use TOSBase, the mote forwards the packet it hears on the radio interface over the UART to the USB port of the PC, where we use a ftdi driver to convert it to a serial packet. The Listen program listens for these packets and can output them to the screen or to another port using SerialForwarder.
Am I making a mistake in my understanding about the way things work? Can anyone point out if there is a problem ... So effectively can i also write a C program to listen on a port and receive all the packet that SerialForwarder is forwarding on a port???
ThanksRegards-- Dattatraya-Work fascinates me, I can stare at it for hours...!!

Re: [Tinyos-help] Serial Forwarder & Sky Motes

[Michael Schippling]

I don't think you need the SF on PC1. Clients should be able to connect
directly to SF on PC2 using the MOTECOM or command line "[EMAIL PROTECTED]:7000"
setting.

Have you tried running Deluge on PC2 directly to the USB port and then
connecting to the PC2 SF? That would eliminate at least one hop to get
started...

Hi all,

I'm posting this message because I couldn't run sf properly in my scenario.
The set up is as follows: PC1 <-> (ethernet) <-> PC2. I have a Sky Mote

Below there is what I've done:

- I run sf on PC1 as follows: $ java net/tinyos/sf/SerialForwarder -comm [EMAIL

- on PC1 I run Deluge ping: $java net/tinyos/tools/Deluge --ping

What I get is:
- on the PC1's sf GUI:
 Listening to [EMAIL PROTECTED]:7000
 Platform telos
 Listening for client connections on port 7000

- Deluge hangs:

Deluge doesn't go through.

Do you please have any suggestions? What am I missing?

It looks like I misspoke; David Gay has written the first parts of the
toolchain (sf, sflisten, etc). They're in

tinyos-2.x/support/sdk/

where there's  

java
python
c

as the three language options.

A full C toolchain (mig/ncg/sf) is one of the "to do" items for 2.x. The
WG has been talking about coming up with a list of things which the WG
believes 2.x needs (and so if written, would be incorporated). We've
been working through moving some TEPs out of draft, so haven't had a
chance to do this yet, but hopefully it will be appearing soon.

I checked out the CVS version of SerialForwarder but the problem remains. 
Should that be the latest version of SF?

Well xlisten's code to connect to a serial forwarder is buggy and
won't work with an old serial forwarder (pre 1.1.8 or so). That might
be the problem...

"[EMAIL PROTECTED]:9001") I can get a client connection. Why not with xlisten? I
