I’m using a Xenon (OS 1.5.2) with a Particle Ethernet FeatherWing. I’ve got the Xenon’s Ethernet capability turned on via the Particle mobile app, and the Xenon is recognized by [Particle.io](http://Particle.io) (logged on via my mesh network via an Argon). Ethernet is plugged in on the Particle Ethernet FeatherWing - getting blink light - and ready to test.

I’m using the sample application sketch provided by Particle here:

        auto ret = if_request(nullptr, IF_REQ_DRIVER_SPECIFIC, &remap, sizeof(remap), nullptr);
        if (ret != SYSTEM_ERROR_NONE) {

            delay(500);
            System.reset();
        }
    }

    Particle.connect();
}

void loop() {
    static system_tick_t lastPublish = millis();
    static int count = 0;
    static bool reconnect = false;

    if (Particle.connected()) {
        reconnect = false;
        if (millis() - lastPublish >= 10000UL) {
            Particle.publish("mytest", String(++count), PRIVATE, WITH_ACK);
            lastPublish = millis();
        }
    }

    // Detect a network dropout and reconnect quickly
    if (!reconnect && !Ethernet.ready()) {
        Log.info("Particle disconnect...");
        Particle.disconnect();
        waitFor(Particle.disconnected, 5000);
        Log.info("Network disconnect...");
        Network.disconnect();
        Particle.connect();
        reconnect = true;
    }
}

```

When I compile this, I get several errors:

Anyone have any thoughts on where to start with troubleshooting? Issues seem to be in the code provided. Just trying to get a positive test that the Particle Ethernet FeatherWing works.

That code will only work with Device OS 3.3.0 and later, which have `FEATURE_DISABLE_LISTENING_MODE` and pin remapping. Neither of those features are implemented in 1.5.x.

Since you’ve enabled Ethernet support, you shouldn’t need any of the extra code.

OK, thanks. Will look into this further.
