Publish local ip to the cloud

General

How can I modify this code to publish my Photon’s ip once every ten seconds?
void setup() {
Serial.begin(9600);
while(!Serial.available()) Particle.process();

// Prints out the local IP over Serial.
Serial.println(WiFi.localIP());
}

how about trying something like this:

IPaddress myLocalIP = WiFi.localIP();
char message[64] = ""
sprintf(message, "My Local IP= %d:%d:%d:%d", myLocalIP[0],, myLocalIP[1], myLocalIP[2], myLocalIP[3]);
Particle.publish("myLocalIP", message);

I got some errors

test.cpp:1:1: error: ‘IPaddress’ does not name a type

^

test.cpp:3:1: error: expected ‘,’ or ‘;’ before ‘sprintf’

^

test.cpp:4:1: error: ‘Particle’ does not name a type
#line 1
^

make[1]: *** […/build/target/user/platform-6test.o] Error 1
make: *** [user] Error 2
Flash unsuccessful.

a few typos…

  IPAddress myLocalIP = WiFi.localIP();
  char message[64] = "";
  sprintf(message, "My Local IP= %d:%d:%d:%d", myLocalIP[0], myLocalIP[1], myLocalIP[2], myLocalIP[3]);
  Particle.publish("myLocalIP", message);

There are a still some more

test.cpp:3:10: error: expected constructor, destructor, or type conversion before ‘(’ token

      ^

test.cpp:4:3: error: ‘Particle’ does not name a type
#line 1
^

make[1]: *** […/build/target/user/platform-6test.o] Error 1
make: *** [user] Error 2

compiled fine for me:

int lastUpdate = 0;

void setup() 
{
  
}

void loop()
{
    if(millis() - lastUpdate > 10000UL)  // 10 seconds
    {
        IPAddress myLocalIP = WiFi.localIP();
        char message[64] = "";
        sprintf(message, "My Local IP= %d:%d:%d:%d", myLocalIP[0], myLocalIP[1], myLocalIP[2], myLocalIP[3]);
        Particle.publish("myLocalIP", message);
        lastUpdate = millis();
    }

}

It worked for me now. Thanks you are awesome!
