I would like to develop my own central device to communicate with the RedBear Arduino shield. The RB device uses a from of UART communications to send data to/from Android...
I was wanting to use a nRF24L01 with a breadboard but its pin-out didn't allow it. A solution then occurred to me based on parts at hand. I wrote it up with instructions and...
Hello. Can I get a literature to the nRF51 series?
I need a full abstraction of the nRF51, like a book or other information, it's structure schematic of build-in modules...

Today I tried to find the better ways to debug program on nRF52840 PDK from CLI on linux.
The ways that I tried
[Failed] openocd (both stlink and jlink) & gdb
[Succeeded] JLink & JLinkGDBServer &…
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…
