Just like the groov EPIC firmware update 3 weeks ago, we have added WPA-2 Enterprise WiFi connectivity to the groov RIO MM1, MM2 and EMU (Energy Monitoring Unit).

Read about the features, enhancements, and various fixes you'll get in the groov EPIC 3.6 firmware release.

You'll see some really amazing updates this year. Meanwhile, while it's exciting to be working on new hardware and software, we also know that regular updates that address some "pebble in the shoe" discomfort are just as important. Our 3.6.0 firmware release adds a few new features and takes out a few pebbles for some nice quality-of-life improvements.

Let’s do a quick unpacking of this new EPIC firmware release.

New features and improved performance are available on groov I/O modules with the click of a button.

A well-known electric car company is somewhat famous for its ability to add features and fix bugs with over-the-air updates to millions of cars. Of course, they are not the only ones with this feature. Many companies have been updating their hardware with firmware updates for decades, but it really captures the imagination when the hardware is something you drive.

Closer to our hearts and minds, Opto 22 has been adding features and squishing bugs on our controllers for more years than most of us can recall (it's our 50th year in 2024!). There are a few SNAP I/O modules that can have their firmware updated via our PAC Manager program—the serial data ones for example—but now with groov EPIC and RIO, ALL our modules can have new features and refined performance added at the click of a button.

The latest groov RIO 3.5 firmware update offers a CODESYS programming option along with enhancements for performance and security.

groov RIO firmware 3.5 is here! And the big news is the CODESYS runtime engine has been added. That means now you can run a control program on groov RIO—one you build in CODESYS using any of the IEC 61131-3 compliant languages.

The engineers have kept their fingers on the keyboard here at Opto HQ and are beyond excited about the release of version 3.5 firmware for the groov RIO family. We can't wait to see what applications our awesome customers come up with, now that the CODESYS runtime engine has been added to the complete groov RIO Trio.

Get Sparkplug 3.0 compliance, updated Node-RED, and new options for your groov EPIC controller.

The engineers at Opto 22 have been busy working around chip shortages and supply chain delays, yet even with those additional efforts, we're announcing the release of a new groov EPIC firmware update, version 3.5.

If I had to sum things up, I’d say a lot of really nice quality-of-life improvements and solid bug fixes were the key takeaways here.

Let's take a high-level look at some of the new features in this release.

A quick fix update was just released for groov RIO, version 3.4.1.

As an OptoBlog subscriber, you're always the first to hear about product news or firmware updates. This time we have another recent release for groov RIO to tell you about.

Review some important bug fixes included in the latest groov EPIC firmware update 3.4.3.

Everyone here at Opto 22 knows that updating any controller's firmware is not a trivial task, and when in a production environment, it’s not something that can be done at the drop of a hat.

That said, sometimes we fix some bugs that require a minor point firmware update and the latest 3.4.3 release is just such a case. If you are using groov View or the new Data Services feature, then you should look closely at this release as you determine where updating your controller(s) should be prioritized in your jam-packed schedule.

Major release adds embedded OPC UA server, expanded MQTT/Sparkplug options, SNMP, Scratch Pad data access, and more

Everyone here at Opto is very excited to announce that the latest EPIC firmware update is now live.

Just as you update the OS on your phone to get the latest improvements in security, stability and performance, the OS on your groov EPIC is no different. It is after all, a quad core Linux computer, so updates are very important for the exact same reasons: security, stability, and performance.

And often these updates come with some cool new features. With this release, you'll find several.
