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 ...

A common thing to do is to use the Nordic UART Service for quick prototyping. Often the example itself is used as a starting point (ble_app_uart). But sometimes we use other starting points, and want to include parts of another example in our ap...

Did you know you can use two-factor authentication to enhance the security of your DevZone account? In this little blog, I’ll show you how to enable Two-Factor Authentication (2FA) with your DevZone account. What is it? In general, Mu...

The SDK software architecture has been hugely changed since SDK v13.0. With adding SDH to SDK, it provides SDH API to  Enabling the SoftDevice and its event interrupt. Disabling the SoftDevice. Receiving stack events from the SoftDevice and for...

The Bluetooth SIG released an errata for the 4.2 and 5.0 versions of Bluetooth specification on July 23rd relating to a potential vulnerability with the pairing procedures. For Bluetooth low energy; this only impacts the low energy secure connections...

The Thingy:52 IoT Sensor Kit is a fancy development board that combines the nRF52832 SoC, a handful of sensors and user interface components, and a rechargeable battery. Although the Thingy is available for sale in the usual places, Nordic has also g...

nRF Mesh are open source libraries for building your own Android and iOS Bluetooth mesh apps. It is also the name of the apps demonstrating a subset of the capabilities of the libraries. Use them in test and verification during development, and to bu...
