Bluetooth 5 Advertisements (Extended and Periodic Advertisements)

We’ve all seen the hype on 2x Speed, 4x Range, and 8x Advertising data increase capabilities in Bluetooth 5.

But what does this all mean?? How does it achieve all these improvements? Is it really possible to achieve all these simultaneously?? What about power consumption?

In this blog post (first in a series of posts on Bluetooth 5), I go through each of the new Bluetooth 5 features. Other topics covered include:

  • Overview of Bluetooth 5 and its major improvements
  • How Bluetooth 5 achieves higher speed and longer range
  • General overview of Bluetooth advertising
  • Types of Bluetooth 5 advertising...

Unique Thread/Bluetooth multiprotocol solution with nRF5 SDK for Thread and nRF52840 SoC by Nordic

With the nRF52840, we released our first System-on-Chip (SoC) with a radio that is capable of running the IEEE 802.15.4 PHY, additionally to Bluetooth 5 (Bluetooth Low Energy), ANT+, and proprietary 2.4 GHz protocols. In March 2017, we released our first software solution running on top of the IEEE 802.15.4 PHY - nRF5 SDK for Thread in version 0.8.0, supporting the OpenThread stack.

Multiprotocol with nRF5 SDK for Thread

Since nRF52840 supports multiple radio protocols, applications running on this SoC can use several radio protocols. With the release of nRF5 SDK for Thread in...

What mom didn't tell you about ble_app_att_mtu_throughput on the nRF52840 evaluation board

Introduction:

This is a guide for the uninitiated, which I am most qualified to write. These tips cover the items I wish I had understood when I got my evaluation kits. Nordic support covered these items but I thought it might be helpful as one newby to another to publish my notes on how I got these kits up and running.

Hardware Setup:

You will need two of the nRF52840 Preview DK boards and download and install both the nRF5-SDK-zip and the nRF-Connect-Windows. This will give you the basic tools to load this evaluation onto the boards. You may also...

The complete tutorial for developing and debugging nRF52 applications on a Mac

I realize that there are already multiple tutorials on how to configure GCC along with Eclipse or SEGGER Embedded Studio (for use on a Mac), but this tutorial goes over setting up a different IDE. The more choices the better, right? ;)

The IDE of choice for me is NetBeans. NetBeans is well known for Java development but not as much for C/C++ or embedded. However, I personally have been using it for embedded development for about 10 years now (both embedded Linux and MCU-level development). In this tutorial, I'll be going over how to set up and configure...

Bluetooth 5 2Mbps Demo with nRF52 Series and Samsung Galaxy S8

Bluetooth 5 - now arriving in smartphones

As we know, Bluetooth 5 was launched last December by the Bluetooth SIG. The nRF52 Series from Nordic have always had Bluetooth 5 and its arrival in the mix for the nRF52 Series and this family of SoCs was designed early on to be able to meet the exciting new features of Bluetooth 5. Smartphones play such a key role in most Bluetooth products that their adoption of new Bluetooth features is always eagerly anticipated, as this is fundamental to the use of new Bluetooth features.

The Big News: Samsung Galaxy S8 supports Bluetooth...

Throughput and long range demo

The new Bluetooth 5 specification promises twice the speed and 4 times the range. Doubling the speed is achieved by increasing the on-air datarate to 2Mbps, while quadrupling the range is achieved by lowering the bitrate to increase the sensitivity of the receiver. We at Nordic have made a demo showing these features with our newest SoftDevice(s) and specifically our newest chip, the nRF52840. It was showcased at CES 2017 in January.

Here is a more in depth description of the demo.

The demo is based on the ATT_MTU throughput example in SDK 13.0.0-1.alpha, which allows...

nRF52840 long range demo

In December we published a video showing a long range test with the newly released nRF52840 chip. The video showed that the nRF52840 had excellent range, and is fully compatible with the new Long Range feature of the just released Bluetooth 5 specification. This blogpost will go into more details about how this test was done. Below is the video for those that have not seen it yet.

The setup consisted of two nRF52840 Preview Development kits, one transmitter (TX) and one receiver (RX). Both kits were connected to a GPS module using serial communication (UART). The DK on the...
