FX9500 LLRP User Application Connection Issue

1k Views Asked by At

I'm working with a Motorola (Zebra) FX9500 RFID reader and trying to get a user application running that integrates with the LLRP Toolkit. The FX9500 comes preloaded with JamVM that supports java 1.5. My test application is simple: connects to the reader, deletes any RO_SPECs, then disconnects. When I run the application from my dev machine I'm able to execute with no issue. When I upload and run the program as a User Application on the FX9500 I get the message below when trying to connect to the LLRP server on the reader:

org.llrp.ltk.net.LLRPConnectionAttemptFailedException: Connection request timed out after 10000 ms.
    at org.llrp.ltk.net.LLRPConnection.checkLLRPConnectionAttemptStatus(LLRPConnection.java:69)
    at org.llrp.ltk.net.LLRPConnector.connect(LLRPConnector.java:149)
    at LLRPReader.connect(LLRPReader.java:15)
    at LLRPMain.main(LLRPMain.java:26)

I get this message after about 4 seconds - not the full 10 seconds timeout specified. Below is my connect method:

public void connect(String ipAddress) {
    try {
        System.out.println("Connecting to reader " + ipAddress);
        reader = new LLRPConnector(this, ipAddress);
        ((LLRPConnector) reader).connect(TIMEOUT);
    } catch (Exception e) {
        e.printStackTrace();
        System.exit(1);
    }
}

Unsure if this is code related (my code or LLRP Toolkit), or something specific to JamVM/FX9500.
