Nordic Thingy:91 Cellular IoT Prototyping Platform Comes with 16 Sensors

Nordic Semiconductor launched the Nordic Thingy:52 back in mid-2017 in the hopes of bringing app and web developers into the hardware ecosystem as fast and easy as possible. The Nordic Thingy:52 was a Bluetooth 5 IoT sensor development kit based on the company’s nRF52832 WiSoC. Although the Nordic Thingy:52 kit is still very much available for purchase and support always available, Nordic Semiconductor has gone further launching a new development kit called the Nordic Thingy:91 targeting cellular IoT applications. The Nordic Thingy:91 is a cellular IoT prototyping platform with support for LTE-M, NB-IoT plus GPS option. Even though IoT connectivity standards like LoRaWAN, BLE, WiFi, ZigBee, and others are very much growing and expanding, Nordic Semi is fully backing cellular technology, something that has very much been available and most likely will still keep been available, and the adoption of 5G is another testimony to that. Cellular is here, and […]

$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 […]

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 […]

U-Blox announces NINA-B3 Bluetooth 5 Wireless MCU Modules

Bluetooth 5 promises to quadrupling the range and double the bandwidth of Bluetooth LE connection. However, we’ve seen not all Bluetooth 5 solutions will provide all features in a comparison between Nordic Semi nRF52840 vs nRF52832 vs nRF52810 Bluetooth 5 ready SoCs, as while all three platforms will handle the higher bandwidth just fine, only the nRF52840 will extend the range up to 4 times. That’s why you want want to make sure you get recent hardware capable of fully handling Bluetooth 5, and U-blox has just announced NINA-B3 Bluetooth 5 module series, based on nRF52840 SoC, that will both provide longer range and higher bandwidth. U-blox NINA-B3 module comes in two family flavors: NINA‑B31, comes pre‑flashed with u‑blox’s Connectivity Software, eliminating the need for embedded programming. Support for AT command set, and u-Blox low energy serial port service NINA‑B30 using nRF52840’s ARM Cortex-M4F as an “Open CPU” that allows […]

Nordic Semi nRF52840 vs nRF52832 vs nRF52810 Comparison for Bluetooth 5 Applications

Bluetooth 5 was formally introduced earlier this year with promises of four times the range, and twice the speed. Several companies offer chips that are compatible with the new standard, and among them Nordic Semi offers Bluetooth 5 ready solutions via nRF52840, nRF52832, nRF52810 Bluetooth SoCs. However, if you thought – like I did – that all three would provide the same Bluetooth 5 support with just some differences in memory, storage and performance, a comparison table put together by Raytac Corporation will show that among the three SoCs only nRF52840 will support the longer range, while the two older SoC only support the extra bandwidth offered by Bluetooth 5. I could find a blog post about a long range demo that confirms the above: Two nRF52840 Preview Development Kits (PDK) or nRF52832 Development Kits. A combination of the two different kits can also be used. Notice that if the […]
