Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...

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 &…
We have produced a video tutorial in two parts about Bluetooth low energy. The purpose is to give you a developer’s introduction to BLE and the development tools offered by Nordic Semiconductor.
NB! Please…
Introduction
In a variety of use cases there is a need to share a common clock among multiple devices. Such a common clock can be used for many purposes, for example by having each node in a network perform…
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…
