$10 Nordic Semi nRF52840 USB Dongle Supports Bluetooth 5, Thread, ZigBee, 802.15.4, ANT and 2.4GHz Proprietary

Several weeks ago, as I noticed the lack of Bluetooth 5 USB dongles, I found MakerSpot CC2640 Bluetooth 5 USB stick based on Texas Instrument CC2640R2F Arm Cortex-M3 WiSoC. It’s not exactly a consumer products, and instead it’s more like a development kit, but it can still be inserted into the USB port of your computer or development board. Today, I found out Nordic Semi also made their own Bluetooth 5 – or is it Bluetooth 5.0 now, I’m really confused at this point – USB dongle for evaluation & development based on nRF52840 WiSoC. It’s not only for Bluetooth 5 though, as the multi-protocol SoC also supports Bluetooth Low Energy, Bluetooth Mesh, Thread, Zigbee, 802.15.4, ANT(+), and 2.4 GHz proprietary solutions. nRF52840 USB dongle (PCA10059) key features: Wireless Connectivity – Bluetooth 5, Bluetooth Low Energy, Thread, Zigbee, 802.15.4, ANT/ANT+, and 2.4GHz USB – USB 2.0 ports Expansion – 15x […]

Two Interesting Projects on Github: Zigbee to MQTT bridge & “Deep Painterly Harmonization”

Hey Karl here. I thought I would try and showcase some GitHub projects that I run into that seem interesting or fun. This week I will start out with 2 projects. Zigbee to MQTT bridge The first one today is a Zigbee to MQTT bridge. Previously we did a couple articles with 433MHz bridges for home automation, a diy RF bridge and one by Sonoff. This bridge is similar but with Zigbee. Unfortunately 433MHz typically have one way communications, and when a message is sent there is no response and the system has to assume the message is received. Zigbee is a 2 way protocol and an acknowledgement can be sent back. The code is moving fast right now and blowing up my GitHub notices. It is a little bit of a mystery on how this works right now with the parts list, but seems to be working for some […]

hIoTron Modular & Enterprise IoT Development Kit is Designed for Fast Prototyping

hIoTron modular & enterprise IoT development kit is described by the company has a “fully pre-programmed prototyping kit for quickly building and testing your IoT concept” with plug-n-play module allowing for flexible prototyping. Beside the hardware comprises of a gateway and nodes, the kit also integrates with the company’s enterprise IoT Platform enabling easy design of custom mobile application & GUI dashboard. The company offers standard, advanced, and custom kits, but to keep things simple, let’s focus on the content of their standard kit first: Hi-Gate IoT gateway: WiSoC – Texas Instruments CC3200 Arm Cortex-M4 @ 80 MHz with 1MB flash, 256KB RAM Storage – 1MB serial flash, 512KB EEPROM Connectivity 802.11 n/g/n Wi-Fi, 2G GSM/GPRS (optional 3G/4G), ZigBee, BLE 4.0, sub-1GHz RF/NON RF to REST/MQTT gateway Expansion – 2x GPIO port pins, 2x analog port pins Power Supply – 9-12V DC 3x modular Hi-Nodes (up to 25 supported per […]

Nordic Semiconductor nRF52840 Multiprotocol SoC Adds Support for Zigbee 3.0

Nordic Semiconductor nRF52840 was introduced in late 2016 as one of the first Bluetooth 5 ready SoC, and it’s the only part from Nordic that fully supports Bluetooth 5 longer range. But the chip is actually a multiprotocol SoC and beside Bluetooth, 802.15.4, Ant, Thread and 2.4 GHz proprietary are also supported. The company has now announced one more wireless protocol working on nRF52840: Zigbee 3.0. The company has released the first engineering release for Zigbee on nRF52840, but the production grade Zigbee 3.0 certified release is planed for H2 2018. The new protocol will be enabled in the S410 v6.0 SoftDevice release. Bluetooth and Zigbee can run concurrently meaning for example you could create an nRF52840 gateway to control Zigbee smart lights from a smartphone connected over Bluetooth 5. The SDK includes examples for concurrent operation of Zigbee and Bluetooth 5 for a smart light bulb and switch. The […]

RushUp KITRA Board Family is based on Samsung Artik 020, Artik 520/530, or Artik 710 Modules

Samsung first announced their Artik IoT modules almost three years ago, and until recently most Artik related products or development kits came from Samsung themselves, with no third party involved. But this has started to change recently with announcements such a Seeed Studio Eagleye 530s low cost development board based on Artik 530 module, and Resin.io Project Fin combining RPI CM3L module with an Artik 020 module for low power Bluetooth connectivity. But as I flicked through Resin.io supported hardware, I discovered they also supported Linux powered Artik 520 and Artik1020 module, as well as some new “KITRA” boards I had never heard of, and if we visit RushUp company website, we can see they have a bunch of Kutra boards and one IoT gateway based on Artik modules: KITRA 520 – Samsung ARTIK 520 product accelerator for advanced IoT KITRA 710 – Samsung ARTIK 710 product accelerator for advanced multimedia […]

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 […]
