New Features That’ll Make Your Circuits Tingle

User-inserted image


New Control Command: GetAddress for Connection Skill

Need to know exactly where your EZB is hiding on the network? Introducing GetAddress - the ControlCommand that gives you the IP address portion of the connection string for a specific EZB index.
Now your robot can whisper its coordinates back to you like a digital secret agent. Check out the Connection skill cheatsheet for syntax, usage, and how this might just save your butt when you’re managing fleets of EZBs like a boss.

Example: Connect the EZB v4 WiFi Camera with the IP Address of the EZB.


New Control Command: GetStatus for Connection Skill

Is it alive? Is it connected? Is it ghosting you?
Use the GetStatus command to return the connection status of a specified EZB. No more guessing, no more elaborate retry loops - just ask and it shall reveal its fate.

Tip: Combine this with GetAddress and suddenly you're running the Mission Control of your own robot army.


The Cognitive Face Cloud Service Is Back, Baby

We found it. We dusted it off. We plugged it in. And now - the Cognitive Face cloud service is restored and better than ever.
Give your robot the gift of facial recognition again, so it can tell the difference between you and your evil twin. Or maybe just remember who keeps unplugging it.

Bonus: You’ll get confidence scores, emotion detection, and the occasional robo-side-eye when it recognizes your mother-in-law.


New Timeout Support for ADC, Digital, and servo Wait Commands (Python + JavaScript)

No more getting stuck in infinite waits because your sensor’s feeling moody.
We’ve added timeout support (in milliseconds!) to the WAIT script commands in Python and JavaScripts. The details have been updated in their appropriate documentation pages in the support section of the website.

Now your robot can give up politely and move on with its life.


Bug Fix: String Concatenation with EZ-Script & Global Variables

We fixed a sneaky little bug where concatenating strings with EZ-Script or global variables wasn’t playing nice.
Now everything behaves as expected - "Hello " + "World" finally equals "Hello World" again.

Robots of the world, unite - your strings are finally whole.


What’s Next?

We're brewing more updates in our silicon cauldron. But for now, go ahead and explore these new commands, bug fixes, and restored features. Your robot's never been this ready for action.
