The nRF9160 is an exciting addition to Nordic's lineup of processors and radios. Ever since the announcement of a Nordic cellular product, I was chomping at the bit to dive in. And boy, did I get that opportunity! In this post, I'll break down some ...

Introduction The pairing-based cryptography (PBC) differs considerably from the prior cryptosystems. It covers many novel cryptographic applications that are hard, if not impossible to construct with other known cryptographic primitives. The PBC...

Introduction Machine learning(ML) is a still growing field, and with the TensorFlow Lite port, there is now support for machine learning on microcontrollers. TensorFlow is an end-to-end ML-platform owned by Google. We want to use TensorFlow Lite to i...

For the longest time we’ve had this idea, of turning one of our most-used Swift Collection Types into a simple one-instruction comparison call, down at the assembly level, to check whether an element belongs to or not in a Set-like data structu...

Overview For these nRF9160 current measurements, the Qoitech Otii Arc and its accompanying software will be used. If you are familiar with the Nordic Power Profiler Kit (PPK), the operation of this device will look very simil...

We released a small update late last week. It’s a follow-up to our last release of 2019, and like its predecessor, this release, 2.1.2, aims to improve the general stability of nRF Connect for iOS as well as take care of some of those loopholes...

This blog post contains answers to questions asked during the "Embedded Antennas for IoT" webinar hosted by Nordic Semiconductor 17.10.2019. You can watch a recording of the webinar here. You can download the slides at the bottom of this po...

It has taken a lot longer than we previously thought, but we made it here, to our first big point release for nRF Connect 2.0. Throughout this “two-point-oh" journey, you’ve been an invaluable asset to us, both for your patience, your sup...

This page describes an easy workaround for the flashing error you get in Keil uVision when you are using nRF5 SDK v16 on nRF52833 chips.  The assumption is that you have installed the latest versions of nRF MDK and nRF-Command-Line-Too...

The nRF9160 SiP supports the use of both LTE-M and GPS. We want to show how these can be used in an application at the same time. In this project we demonstrate this by using the nRF9160 DK to send the GPS position of the DK to Google Cloud, which w...

This blog post contains answers to questions asked during the "Introduction to nRF Connect SDK" webinar hosted by Nordic Semiconductor 25.09.2019. You can watch a recording of the webinar here. You can download the slides at the b...

It's been a month since we last spoke, when we announced the release of nRF Connect for iOS 2.0. What a day that was, wasn’t it? In any case, we’re here because, since then, we’ve made three successive bug-fix releases. With&nb...

There are smart home applications that require an extended radio range. Is it possible to use Zigbee/BLE multiprotocol solution to increase the Zigbee mesh network coverage?

This blog post contains answers to questions asked during the "Introduction to Nordic Thingy:91" webinar hosted by Nordic Semiconductor 22.08.2019. You can watch a recording of the webinar here. You can download the slides at the bottom of this ...

Thingy:91 FAQ Should I update to the latest firmware? Yes, its recommended to update the firmware to get the latest and greatest functionality. See Update Thingy:91 firmware. What if I want to try it on NB-IoT? Due to restrictions in use of TC...

For the past ten months, we’ve been busy, hunkering down in front of our keyboards, keeping the blinds down, shooting mean looks at our bosses whenever they dared interrupt us. And of course, all the while, we were blasting some Linkin&nbs...

The production firmware version v1.0.0 is released for the nRF9160. - Release notes for the nRF Connect SDK v1.0.0 (NCS) - Release notes for the Modem Firmware v1.0.0 (MFW) Update NCS to v1.0.0: cd ncs/nrf git checkout master git pull ...

Google I/O was wrapped up last week. One session was particularly interesting: "Connect Thread Devices to the Cloud with IoT Core". In it Google explains how the Thread protocol and their Cloud IoT Core are the future of IoT connectivity. T...

This blog post complements the video with the same title, see this. Introduction There are many sources of information on the web trying to characterize the new low power cellular technologies LTE-M (Cat-M1) and NB-IoT (Cat-NB1). Unfortunately, ...

Recently, we've updated the SEGGER Embedded Studio Nordic edition (SES) to version 4.16 (SES Nordic Edition is special version of SES built specifically for nRF Connect SDK).  This updated version introduced some new features to support bui...

Range testing of any RF scheme is inherently limited by the RF environment, antenna design, tuning and many other factors. The usefulness of range testing is to provide a basis for comparison while keeping as many variables as possible constant. When...

This blog post describes how you can take advantage of the 4 MOSFET's on the Thingy:52. DISCLAIMER: Please verify all information that is used/retrieved from this blog post. Some of the information might be inaccurate as this blog post has not b...

The Power Profiler Kit (PPK) is a flexible tool for measuring the real-time current draw of nRF5x designs. When used as an add-on board to measure the nRF5x current of an attached development kit (DK), the process is straightforward. Connecting an ex...

This blog was last updated 17.01.2019. The Bluetooth Special Interest Group (SIG) recently announced the deprecation and withdrawal of Bluetooth Core specifications v4.0 and v4.1. For products that are already qualified, there is no impact. For produ...

This blog describes how you can setup a Segger Embedded Studio example for PCA10040E (emulating nRF52810) from nRF5 SDK 14.2 to use S132 v5.1.0, instead of S112. The procedure should be similar for the other toolchains. nRF5 SDK 14.2 officially ...
