Hello Devzone,
In our product we are working with a nRF52840 microcontroller and periodically transmitting large sums of data to a PC or a phone.
We noticed that over...
Introduce
WIZnet would like to introduce a BLE to TCP solution which enables bluetooth devices to access cloud services such as Google, IBM, and Amazon without a smartphone. WIZnet created a low power…
Introduction
There is a use case that I've seen several times recently that I find interesting due to the fact that its security requirements aren't directly addressed by the Bluetooth Low Energy (BLE…
The Zephyr Project RTOS
The Zephyr Project RTOS is a recent effort by the Linux Foundation to provide the embedded world with a free, secure and fully-featured Real Time Operating System. It is designed…
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…
Requirements
This document uses:
Segger Embedded Studio (SES)
nRF5 SDK v17.1.0
an nRF52 DK to emulate the nRF52810
a BLE-enabled mobile device

Requirements
This hands-on tutorial uses:
Segger Embedded Studio (SES)
nRF5 SDK v17.1.0
an nRF52840 DK
a BLE-enabled mobile device
You can use an nRF52 DK or nRF52833 DK instead of the nRF52840 DK,…
This is part 3 of the series Building a Bluetooth application on nRF Connect SDK
You can find other parts here:
Part 1 - Peripheral Role.
Part 2 - Central Role.
In Part 1 we covered the generic architecture…
Purpose
The purpose of this guide is to demonstrate the use of Bluetooth Shell. Bluetooth Shell (BT Shell) is a command-line shell application that runs over the UART. It allows one to manually type in…
Out of the box, the examples in the nRF Connect SDK are configured for ease of use, functionality, and debugging; they are not generally configured for optimal memory utilization. Some of the examples…
