Hi Nicole,
In this case, forget about the thread thing and try this instead. I see
now the problem: you declare a class variable MoteIF, but you then
declare the same variable again in the init() method, thus hiding the
class variable. So in your message handler the variable moteIF is null.
To solve the problem, just remove the datatype declaration in the init
method. The code below also gets you rid of the infinite loop (just
replace the init() and the handlerType1() methods in your code with this
code).
Cheers,
Urs
public void init(String source) {
PhoenixSource phoenix;
if (source == null) {
phoenix = BuildSource.makePhoenix(PrintStreamMessenger.err);
} else {
phoenix = BuildSource.makePhoenix(source,
PrintStreamMessenger.err);
}
moteIF = new MoteIF(phoenix);
moteIF.registerListener(new UpflowResultMsg(), new MessageListener() {
public void messageReceived(int to, Message msg) {
handlerType1(to,msg);
}
});
moteIF.registerListener(new VerificationResultMsg(), new
MessageListener() {
public void messageReceived(int to, Message msg) {
handlerType2(to,msg);
}
});
}
private void handlerType1(int to, Message msg) {
if (msg instanceof UpflowResultMsg) {
UpflowResultMsg rmsg = (UpflowResultMsg)msg;
System.out.println("UpflowResultMessage received. Nonce = " +
rmsg.get_rndNonce() + " aggregated data " +
rmsg.get_aggregatedData() + " ");
moteIF.send(1, msg);
System.out.println("Sending UpflowResult starting 2.Phase");
}
}
