Convert IPAddress to String for use with Spark.publish()

[G65434_2]

Hi @cwade

I think this thread may help you out:

Network.localIP() to String (to get it via Spark.variable())

I am afraid that I don’t know much about the Arduino String class but redefining the name localIP from method to variable seems like a bad idea. Here is some code that worked fine for me. localAddr = WiFi.localIP(); byte oct1 = localAddr[0]; byte oct2 = localAddr[1]; byte oct3 = localAddr[2]; byte oct4 = localAddr[3]; char s[16]; sprintf(s, "%d.%d.%d.%d", oct1, oct2, oct3, oct4); Serial1.print(s); Hope this helps!
