First of all, thanks for pointing me out to those classes, they
clarified my problem a lot
So what you are saying is, I can create PhoenixSources and use them to
create a new MoteIF object which I should be able to use as usual to
send/receive packets, so, for example, if I want to open three USB
connections I can do that creating 3 PhoenixSources and 3 MoteIFs, and I
wouldn't need to use SerialForwarder.
My initial idea was to have a program which would create the
PhoenixSource objects and keep them open, a la SerialForwarder, and have
other programs create MoteIF objects to send and receive messages as
necessary. I couldn't find a way to make this work, though; usually,
MoteIF objects always connect to the serial forwarder using the default
MOTECOM setting, and so they are always created with
MoteIF((Messenger)null), and I can't create it with MoteIF(source5) if
source5 is a variable from another program which is already running
independently...
Anyway, to simplify things a bit, I tried to make it all in the same
program and use just one connection to simplify things, to see how it'd
work without using SerialForwarder. To do this, I made a little program
which should send a message to a Mote and get an answer from it. To
establish the connection, I have tried with:
try {
source = BuildSource.makePhoenix( "serial@/dev/ttyUSB3:telos",
PrintStreamMessenger.err );
m = new MoteIF(source);
m.registerListener(new DimmerControlMSG(), this);
}
But it fails to work. It apparently gets stalled on m = new MoteIF(source); the
message I get on the console is:
getenv JNI library not found. Env.getenv will not work
(please consult installation directions in
tinyos-1.x/tools/java/net/tinyos/util/Env.INSTALL)
Experimental: JNI_OnLoad called.
Devel Library
=========================================
Native lib Version = RXTX-2.1-7pre20
Java lib Version = RXTX-2.1-7pre20
RXTX Warning: Removing stale lock file. /var/lock/LCK..ttyUSB2
I have no idea why this could be happening since I think I am doing it the
"proper" way, and I don't think it's related to JNI.
Any suggestions would be greatly appreciated.
Thank you,
- Jose.
