Discovery not working with echo dot 3rd generation

[jormaechea]

Hi, after a lot of tests I decided to with the docs and try the basic example in the README. So this is my code:

void setup() {

    Serial.begin(115200);

    connectWifi(); // Wifi basic setup, with hardcoded SSID and password

    fauxmo.addDevice("light one");

    fauxmo.setPort(80); // required for gen3 devices

    fauxmo.enable(true);

    fauxmo.onSetState([](unsigned char device_id, const char * device_name, bool state, unsigned char value) {
        Serial.printf("[MAIN] Device #%d (%s) state: %s value: %d\n", device_id, device_name, state ? "ON" : "OFF", value);
    });
}

void loop() {
    fauxmo.handle();
}

But when I ask my echo dot to find new devices, it finds nothing. Is there a problem with this example? Let me know if there is a way to provide some debug logs or something that may be useful.

Update: I'm using a NodeMCU ESP8266 V3 and installed the latest library version of FauxmoESP (3.4.0)

I had the very same problem and it worked by simply rebooting my echo dot. ESP was powered on all day and was not even restarted after the alexa's reboot.

I have the same problem

I moved out to Arduino IOT Cloud, so I can't confirm @kgotsis solution..

From Readme : (2) Arduino Core for ESP8266 requires LwIP set to "v1.4 Higher Bandwidth".

Please make sure you've done this.
