Small question. On the documentation i saw that:
If you implement a function called userFunction() in your embedded code, you can trigger it from the API by including the “message” key in your POST data. The value of the “message” key will be passed as the string argument to your function.
I was wondering if a Spark can call this userfunction to all spark devices in the group (or individual).
For instance: triggerUserFunction(“BEEP”,“Group1”); //All devices on group 1 have userFunction() called and they start to beep.
If not, is there any spark core communication based on wifi available?
