Hi,
Sorry to be posting a lot about my LIS2DH12 on custom hardware lately. I do believe my different inquiries are to be treated as separate.
My (modified) hardware now...
Hello,
we run an application on a custom board with nRF52840 powered by an external power supply and buffered by a supercap. The supercap then provides the energy for the...
EDIT: Sorry to be posting a lot about my LIS2DH12 problems lately, as I'm advancing somewhat while I have open support threads. Newest thread is here: In preparation of this...

Code derived from UDP sample works on DK board but fails on custom device.
Device is using DK board configuration, but no...
I am getting an fs_close() -5 error (-EIO) when I write to an SD card using fatfs. I determined this error was associated with FR_DISK_ERR in fat_fs.c.

We recently announced that we now support “extended industrial temperature range” (-40 – 105C) on our nRF51822.
The devices supporting -40 - 105C are the QFAA (QFN with 256kB flash and 16kB RAM) and the…
Introduction
Using proprietary protocols can be an effective way of addressing shortcomings in BLE. When communicating between two nRF chips, one can for example use a different packet format or different…
Hello everybody,
I have just published the sourcecode of FruityMesh on GitHub. It is a meshing algorithm that uses standard BLE connections. Plug in as many nodes as you like and they will automatically…
When designing a PCB with a high-frequency radio onboard certain rules should be followed for optimal radio frequency (RF) performance. This guide will provide some general PCB guidelines that can be used…
Periodic Advertising with Responses (PAWR) is a new feature in Bluetooth 5.4. It extends the periodic advertising protocol from Bluetooth 5.0. Periodic advertising, where a device sends broadcast data with…

nRF Cloud is a major element of Nordic Semiconductor's long-term and committed plans for cellular IoT solutions. It can be accessed by users or devices through different methods for different purposes…
Introduction
The intention of this guide is to clarify and describe the main aspects relevant to the GNSS receiver functionality on the nRF9160 as well as build configurations, tool recommendations and…
Background
There is a need to enable Nordic hardware with the Direct Test Mode (DTM) firmware. This is so the physical layer and RF characteristics may be ascertained as set in the Bluetooth Sig Specification…
