'device/name' and 'device/random' and 'device/ip' does not work on Photon [Solved]

Cloud

Is anyone aware that this example from the documentation works on Core but not on Photon?

// Open a serial terminal and see the device name printed out
void handler(const char *topic, const char *data) {
    Serial.println("received " + String(topic) + ": " + String(data));
}

void setup() {
    Serial.begin(115200);
    for(int i=0;i<5;i++) {
        Serial.println("waiting... " + String(5 - i));
        delay(1000);
    }

    Spark.subscribe("spark/", handler);
    Spark.publish("spark/device/name");
    Spark.publish("spark/device/random");
    Spark.publish("spark/device/ip");
}

Is this a cloud or firmware issue?

Hi @steelydev

We have had problems in the past like this for which the work-around is adding a delay of say 2 seconds between each Spark.publish() to allow for the round-trip to the cloud and back.

Can you try that and report back?

Just tried that. No luck.

Also added in call to loop() just in case:

    Spark.subscribe("spark/", handler);
    delay(5000);
    Spark.publish("spark/device/name");
    delay(5000);
    Spark.publish("spark/device/random");
    delay(5000);
    Spark.publish("spark/device/ip");
    delay(5000);

}

void loop() {
  Serial.println("Done");
}

@steelydev, the issue has been identified and fixed but waiting for an update to the :cloud:

Thanks. I searched for spark/device/ and spark/device/name. But Iā€™m not sure I would have understood the description of the issue, anyway.

Thank you, Particle, device/name seems to work now!
