Silicon Labs FG28 Sub-GHz wireless and 2.4 GHz BLE SoC supports Amazon Sidewalk, Wi-SUN, etc…

Silicon Labs dual-band FG28 Cortex-M33 SoC comes with sub-Gigahertz and 2.4 GHz Bluetooth LE radios that support long-range networks and protocols like Amazon Sidewalk, Wi-SUN, and other proprietary protocols, as well as a built-in AI/ML accelerator for machine learning inference and SiLabs Secure Vault technology. The chip looks to be an update to the sub-GHz FG25 Cortex-M33 microcontroller with an additional 2.4 GHz BLE radio, but somehow less program memory (up to 256KB) and storage (up to 1024 KB). The peripherals implemented in the chip are almost the same, as the microcontroller gains support for predictive maintenance with a small matrix vector processor for AI/ML acceleration. Silicon Labs FG28 (EFR32FG28) specifications: MCU core – Arm Cortex-M33 @ 78 MHz with DSP instructions and FPU On-chip memory – Up to 256 kB RAM data memory On-chip storage – Up to 1024 kB flash program memory AI accelerator – Matrix Vector Processor […]

Reolink E1 Outdoor Pro 4K smart security camera supports WiFi 6 connectivity

Reolink E1 Outdoor Pro is a 4K smart security camera with PTZ and auto-tracking like the Reolink TrackMix, but instead of relying on PoE or WiFi 4/5, the camera comes with WiFi 6 connectivity for a faster and more stable network connection with less latency. Most of the WiFi security cameras I’ve been using come with 2.4GHz WiFi 4, and I’ve found connectivity to the solar-powered Reolink security cameras I’ve been using to be somewhat unreliable with difficulty connecting to them through the mobile app, although uploads to the cloud don’t suffer from those issues. So I typically prefer PoE or 4G LTE security cameras since the connectivity is more stable, but Reolink E1 Outdoor Pro security camera’s WiFi 6 support could help depending on the environment. Reolink E1 Outdoor Pro specifications: Camera – 4K Ultra HD resolution with 3x optimal zoom Color night vision with spotlight PTZ – 355º […]

Linux 6.3 release – Notable changes, Arm, RISC-V and MIPS architectures

Linux Torvalds has just announced the release of Linux 6.3 on the Linux Kernel Mailing List (LKML): It’s been a calm release this time around, and the last week was really no different. So here we are, right on schedule, with the 6.3 release out and ready for your enjoyment. That doesn’t mean that something nasty couldn’t have been lurking all these weeks, of course, but let’s just take things at face value and hope it all means that everything is fine, and it really was a nice controlled release cycle. It happens. This also obviously means the merge window for 6.4 will open tomorrow. I already have two dozen pull requests waiting for me to start doing my pulls, and I appreciate it. I expect I’ll have even more when I wake up tomorrow. But in the meantime, let’s enjoy (and test) the 6.3 release. As always, the shortlog […]

How to setup a WireGuard server on Ubuntu for remote login

In this article, we will show you how to set up a WireGuard server on Ubuntu in order to use it for remote login. Introduction to WireGuard First of all, let’s first understand, what is WireGuard? WireGuard is a very simple and fast VPN tool with state-of-the-art encryption. Its goal is to be faster, simpler, more streamlined, and easy to use than IPsec, while avoiding the hassle of large-scale configuration. WireGuard is designed as a general-purpose VPN to run on embedded interfaces and supercomputers in many different environments. Originally released for the Linux kernel, WireGuard is now widely deployed and supported across platforms (Windows, macOS, BSD, iOS, Android). WireGuard is growing rapidly and is already considered the most secure, easiest-to-use, and simplest VPN solution in the industry. Basic Concepts of WireGuard Several basic concepts are involved in WireGuard: Peer: A node in WireGuard. Private key: Each node has its own […]

Embedded Open Source Summit 2023 schedule – Zephyr OS, Security, IoT, Embedded Linux, and more

The Linux Foundation has just announced the full schedule for the Embedded Open Source Summit, which will take place on June 27-30, 2023 in Prague, Czech Republic, as well as virtually starting on June 26. Over 175 sessions, birds of a feather (BoF) tracks, and workshops related to embedded and open-source innovation will be presented at the event itself comprised of six micro conferences: Automotive Linux Summit Europe, Embedded IoT Summit, Embedded Linux Conference, LF Energy Embedded Summit, Safety-Critical Software Summit, and Zephyr Project Developer Summit. Even though I’m not going to attend personally, I’ve gone through the schedule to create my own little virtual schedule with some sessions relevant that should be interesting to me and hopefully to CNX Software readers. Monday, June 26 (Virtual sessions) The first day of the event will have a Yocto Dev training in the morning, and a bunch of virtual sessions that are […]
