Publish Example Using Spark.publish()

Getting Started
1

It looks like the Publish example is using spark.publish, which isn’t working. As soon as I changed the lines to Particle.Publish, it started working again.

Where do you see Spark.publish()?
Providing a link helps.

The docs do show Particle.publish().

If you start in the Web IDE, Click Code, Then Click under Example Apps. #4 is Publish. Which is the URL of https://build.particle.io/examples/56214d636666d9ece3000004

 if (beamBroken==true) {
        // If the beam was broken before, then this is a new status.
        // We will send a publish to the cloud and turn the LED on.

        // Send a publish to your devices...
        Spark.publish("beamStatus","intact",60,PRIVATE);
        // And flash the on-board LED on and off.
        digitalWrite(boardLed,HIGH);
        delay(500);
        digitalWrite(boardLed,LOW);

        // Finally, set the flag to reflect the current status of the beam.
        beamBroken=false;
    }
    else {
        // Otherwise, this isn't a new status, and we don't have to do anything.
    }
  }

  else {
      // If you are below the threshold, the beam is probably broken.
      if (beamBroken==false) {

        // Send a publish...
        Spark.publish("beamStatus","broken",60,PRIVATE);
        // And flash the on-board LED on and off.
        digitalWrite(boardLed,HIGH);
        delay(500);
        digitalWrite(boardLed,LOW);

        // Finally, set the flag to reflect the current status of the beam.
        beamBroken=true;
      }

I see.
But when I build that sample it still builds without error for me (on Core 0.5.3, Photon 0.6.0-rc.2).

Still, thanks for pointing that out. I’ll open an issue on the repo for an update.

Thanks! It builds without error. But none of the events show up in the Console. :slight_smile: I am also on 5.3 of the firmware. It isn’t a big issue, but its the little things in life that make me lose my hair.

That’s odd!
@suda, any idea about that?
If Spark.xxxx() was deprecated already, the build should fail :confused:

7

Thanks for catching this! It seems we forgot to update the examples after we deprecated Spark namespace. It should be fixed now (you might need to clear the Build cache).

8

@suda, will the build now fail when using Spark.xxxx() functions?
If they don’t work anymore, a compile time message would be expected.

I just updated the examples to use Particle instead of Spark. An error should appear if someone is using Spark.

10

No it does not!
I just tried that (against 0.6.0-rc.2 and 0.5.3) immediately before posting above comment, and there was no error, only a warning and these are not displayed when there is no breaking error.

Oh you’re right! We’ll need to add some UI to warn users about deprecation even if compilation succeeds.
