Droplit Logo1

Doing some further work with my trusty ARTIK-520 (hey, when you have a hammer, everything looks like a nail! Back up off me! ) I decided to try installing another IoT Gateway framework on it. (I’ve done that before.) Equal opportunity and all that. And I’ll be doing more of them as soon as I get more mini-SD Cards in-house. But I digress.

I originally just followed the basic install instructions for deploying a Droplit.io Edge server. But that didn’t work. No fault of Droplit.io, to be sure. And really no fault of the ARTIK-520. But here’s my new rule:

Do Not Compile/build On ARTIK-520

It just doesn’t ever end well. It may be a pain to set up a cross-compiler on your architecture, but you only have to do that once (and lucky me I already had the ARM compiler toolchain installed and working from working on MyNewt. But you won’t even need a compiler for Droplit.io edge. It’s all JavaScript, so it’s pretty easy.


Once you’ve got the Droplit.io-edge wad on your laptop (or whatever) and all the prerequisites, just build it according to the instructions. Don’t actually run it from your laptop though. Once I had it built, I just ran:

DSimmons-Pro:~ dsimmons$ tar czf droplit.tgz droplit.io-edge

  And then used sftp to copy the compressed tar file over to the ARTIK-520, un-compress/tar it and then:

I set the DEBUG property because I wanted to see what was actually going on behind the scenes (plus I was actually debugging a problem with the Droplit folks, who are awesome about helping out and super responsive!).

You’ll see that very quickly the Droplit-io edge server found the Wemo switches I have deployed in my house. Sweet! I then went to my Droplit.io developer portal and:


And there they are! And I have verified that I can indeed turn them on and off from here.

Now, if anyone wants to send me some Sonos gear, or some Philips HUE gear, that I can install here at home to test with this, I’d be happy to test that out.

I may see about creating some connectors to connect things like my MyNewt-based devices to the edge server, but that’s not going to happen today.


As usual, I have found the ARTIK-520 to be a fairly easy, and very versatile, IoT hub. This is my second gateway project with ARTIK-520 and, though I have run into some quirks each time, it’s basically pretty straight-forward to set up. Again, don’t try to build/compile on the ARTIK-520 unless you absolutely have to, and it’s a relatively small build. I’ve actually built Node.js from source on the ARTIK-520 a couple of times and it was slow, but relatively painless.

Droplit.io is a fairly straightforward deployment target for ARTIK-520. As small as the actual ARTIK module is (aside from all the development board stuff) it would be a pretty attractive target for a Droplit.io ‘appliance’, though I’m not sure the price-point would hit a reasonable target for them.

As I said, I’d like to try my hand at building some connectors for other IoT devices for Droplit, and I’m certainly looking at some other gateways to build/deploy on this ARTIK-520 board. Stay tuned!
