The wait is over! You can now publish data from the Spark Core through the Cloud. Here’s the blog post: http://blog.spark.io/2014/03/11/spark-publish/ Here’s the Particle Docs reference: https://docs.particle.io/reference/firmware/electron/#particle-publish- Don’t want to go to the blog? Well s…

Dave is there an ETA for the “webhook” support?

My hope was to release it this sprint, but there are implications with regards to making sure we’re not spamming services, and wanting to be sure it’s robust. I would estimate it’ll be ready this next sprint. Thanks, David

Ahh… the 80/20 rule. The devil is in the details. I wrote a Node.JS service a couple of weeks ago to post back to “webhooks” for our product at work that has similar throttling capability. Granted, it helps that the webhook destination is maybe 2 rows over in the data center, so it only takes a w…

@zach it would be great to hear what is the best and recommended (and working) way to consume sse events from non-browser clients. In my case that is node.js - I’ve tried to use eventsource but it seems to not work. I have code up and running in the browser, but due to the access token being publicl…

[image] Publish & subscribe semantics & documentation I want to write a publish-subscribe app involving several cores. There isn’t enough documentation (yet?) to know how much work the application programmer must do. Is publish-subscribe reliable? If the publish call does not return an …

Hi guys, Two newbie questions here! In the opening post, where exactly is this printing stuff to? Serial.println(“Motion detected!”); What does the “*” before the text in the syntax examples below mean? SYNTAX Spark.publish(const char *eventName, const char *data); Spark.publish(String ev…

This will output to Serial or COM port on your machine * in programming refers to the pointer of the location of eventName :slight_smile:

What is not immediately obvious to newcomers to the Spark and to the Arduino is that the Wiring programming language is C (or C++) with a few things bolted on to supposedly make things easier. A good C primer will help you no end. To answer your question try http://www.cs.bu.edu/teaching/c/string/…

Thanks! 2 questions from that link: So, PrintLabel() could have been written in two ways: void PrintLabel(char the_label[]) { printf("Label: %s\n", the_label); } OR void PrintLabel(char *the_label) { printf("Label: %s\n", the_label); } In the second case above, there was no need to def…

At the underlying machine code level the usual way to refer to an array is to give the memory address of the first element in the array. C works at a level not far removed from machine code. But whatever language you use, underlying it all, you are right: to change an array you do it one element at …

Perhaps I should have asked here instead?
