Hello everyone, Sry for my english  I have my new spark since yesterday. I tried a few examples and all is working fine. I am completely new in this. I want to check if some devices of my home network are online or not. I have read the documentation and I found this part under the section firmw…

Hi triplea, here is a sample code that worked for me. I hope it helps. IPAddress remoteIP(192, 168, 1, 1); int numberOfReceivedPackage = 0; void setup() { Serial.begin(9600); // Now open your Serial Terminal, and hit any key to continue! while(!Serial.available()) SPARK_WLAN_Loop(…

HI @triplea WiFi is built-in but you do need to watch the capitalization “WiFi”. As @triuman says above you need an IP address to ping and away you go–the default is 5 tries but you can say WiFi.ping(remoteIP, 10); for 10 tries if you need to for some reason. Usually 5 is sufficient and if the …

hi, thx you all for your replys. I will try it immediatly :wink: Wish you a nice day.

Hi again :slight_smile: I tried to ping the device, but unfortunately, I don’t receive Packages, also if I can ping the device from Windows. I tried also to ping the IP-Address of Google. With Googles IP Address, the script is working fine. This is my code: // check IP and Publish IPAddress remot…

I have came to same result. Once WiFi.ping is called, Spark.publish will not work. [image] Time value error during cold boot Troubleshooting OK, I put together a test code to prove the Spark.connected() does not indicate that…

I found a similar thing, I could not get a ping reply from a server’s IP on my home LAN until I logged in to that device and tried to ping back to the IP of the spark. I didn’t get a reply (as spark unhelpfully doesn’t respond to pings) but I think it caused the spark to do an arp lookup and then it…

I know this is resurrecting any ancient thread for which I apologise but in a way it’s perhaps arguably neater than creating a whole new one? Can anyone clarify: do Cores and/or Photons reply to TCP/IP (not Cloud!) pings? I am trying to monitor their availability and I figured running Nagios Core m…

Hi @daneboomer The ping that you are talking about is really called ICMP Echo and happens at a level lower than TCP/IP but that is just technical detail. The answer is complicated: early version of the Core firmware did reply to ping requests but later versions did not. I believe Photon’s reply to…
