Rigado Vesta IoT Gateway Runs Linux and Zephyr OS, Supports Bluetooth 5, 802.15.4, WiFi, Ethernet and Cellular Connectivity

I’ve recently read several open source software news related to Rigado IoT gateway, starting with Canonical announcement last month, that the gateway would ship with Ubuntu Core starting in summer 2018, and a few days ago it popped up again during Linaro CEO keynote at Linaro Connect HK 2018, as one of the first commercial devices to run the Zephyr OS, specifically its fully open source Bluetooth stack on a Nordic nRF52 chip. Rigado Vesta IoT gateway is not exactly new, as it was first announced in December 2016. The hardware relies on an NXP i.MX 6UL Cortex A7 processor, up to 256MB RAM, 4GB eMMC flash, and includes built-in support for dual band WiFi, Bluetooth Smart, Bluetooth 5/4.2, 802.15.4 (Thread), Fast Ethernet with PoE, as well as optional support for a cellular LTE Cat 1 modem. Rigado gateway hardware specifications: Processor – NXP i.MX6 UltraLite (G3) Arm Cortex A7 […]

FOSSASIA Summit 2018 Schedule – March 22-25

FOSDEM is the “Free & Open Source Software Developers’ European Meeting” takes place the first week-end of February every year in Brussels, Belgium. It turns out there’s an event in Asia called FOSSASIA Summit that’s about to take place in Singapore on March 22-25. There are some differences however, as while FOSDEM is entirely free to attend, FOSSASIA requires to pay an entry fee to attend talks, although there are free tickets to access the exhibition hall and career fair. There are also less sessions as in FOSDEM, but still twelve different tracks with: Artificial Intelligence Blockchain Cloud, Container, DevOps Cybersecurity Database Kernel & Platform Open Data, Internet Society, Community Open Design, IoT, Hardware, Imaging Open Event Solutions Open Source in Business Science Tech Web and Mobile Since the event is spread out over four days, it should be easier to attend the specific sessions you are interested in. I’ve […]

Particle Unveils Three nRF52840 Bluetooth 5 Boards: Argon (WiFi), Boron (LTE), and Xenon, as well as Particle Mesh Technology

In the last year or so, Bluetooth has gotten an upgrade with the release of Bluetooth 5. The new protocol works on several existing platforms, but if you want support for the full set of Bluetooth 5 features such as longer range and higher bandwidth, we’ve seen you need a recent chip such as Nordic Semi nRF52840. However so far, AFAIK you had to buy Nordic Semi own development kit for play with nRF52840, and now Particle has announced not one, but three low cost development boards powered by nRF52840 chip starting at just $9, and supporting their newly announced Particle Mesh technology. So for some reasons, it appears they did not go with Bluetooth Mesh. Particle Xenon – Bluetooth 5 + Mesh Xenon is the cheapest model with the following specifications: SoC – Nordic Semiconductor nRF52840 Arm Cortex-M4F 32-bit processor @ 64MHz with 1MB flash, 256KB RAM Storage – […]

Embedded Linux Conference & IoT Summit 2018 Schedule

The Embedded Linux Conference 2018 and the OpenIoT Summit 2018 will jointly take place next month, on March 12 – 14, 2018 in Portland, Oregon, USA. The former is a “vendor-neutral technical conference for companies and developers using Linux in embedded products”, while the latter is a “technical conference for the developers and architects working on industrial IoT”. The Linux Foundation has already published the schedule, and it’s always useful to learn what will be discussed about even for people who won’t attend. With that in mind, here’s my own virtual schedule with some of the talks I find interesting / relevant to this blog. Monday, March 12 10:50 – 11:40 – Progress in the Embedded GPU Ecosystem by Robert Foss, Collabora Ltd. Ten years ago no one would have expected the embedded GPU ecosystem in Linux to be what it is now. Today, a large number of GPUs have […]

CCC Air Stick 4K TV Stick Runs Android TV, Supports HDR10, aptX HD Bluetooth Audio (Japan)

It’s been a while since I have seen an Amlogic S912 TV stick, and so far none of them would run Android TV operating system. But CCC Air Stick 4K does, meaning it supports Google Cast like a ChromeCast, as well as Voice Commands through a remote control. The company also claims support for aptX and aptX HD Bluetooth audio, as well as online services such as Hulu, Netflix, Spotify, and some Japanese specific services, since the TV stick only targets the Japanese market. Air Stick 4K specifications: SoC – Amlogic S912J 64-bit octa core Arm Cortex A53 @ up to 1.5GHz with Arm Mali GPU System Memory – 2 GB Storage – 16 GB flash Video Output – HDMI 2.0a up to 4K @ 60 Hz with HDR10, CEC support Audio – HDMI audio output, aptX / aptX audio over Bluetooth Connectivity Dual band (2.4 GHz/5 GHz) 802.11b/g/n/ac WiFi […]
