Matter is the name of the Internet of Things (IoT) protocol designed to integrate diverse IoT communication systems. This would enable a switch or sensor on one network to initiate an action on another network, such as unlocking a door or turning on a light. Matter is sponsored by the Connectivity Standards Alliance, previously known as the Zigbee Alliance. Matter does support Zigbee, but that's only one of many protocols working with it.

In this video, I talk with Rob Alexander from Silicon Labs about Matter and how it works, including the security structure.

He also discusses Silicon Labs' EFR32BG24 Series (see figure). The system-on-chip (SoC) is built around an Arm Cortex-M33 processor. This family of chips supports Bluetooth Low Energy and 802.15.4. Bluetooth is one way of adding a node to a Matter environment, such as an 802.15.4 mesh network like Thread or Zigbee.

The ERF32BG24 is a wireless SoC based on an Arm Cortex-M33 processor.

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.

I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
