Let’s go ahead and set up the nRF52 USB dongle to include the Battery service and Battery Level characteristic, then connect and interact with it from a mobile app. To verify the device is advertising and working properly, you can use a BLE client emulator app on a mobile phone such as Nordic nRF Connect or LightBlue Explorer. Start by clicking the Start scan button.To perform a scan for advertising BLE devices:

Let’s cover each of these aspects and how to accomplish them using nRF Connect’s Bluetooth Low Energy application. Usually, following a connection, the central will also interact with the peripheral’s GATT server (and vice versa) via reads, writes, notifications, and indications on characteristics.

Connecting to an advertising device (that allows connections).

Discovering advertising devices in the surrounding area.

There are two main aspects of acting as a central device: This is especially useful during the early phases of a project when the mobile companion app is not ready yet and may require a lot of effort to get it working. It saves you from spending hours programming a custom application to perform your own testing. Whether you’re testing a new feature of your BLE device or want to interact with an existing one, using an application that acts as a BLE central ( aka central emulator apps) can help a lot. Now you’re ready to run interface with the dongle and use it as either a BLE central or as a BLE peripheral. you will be presented with the following screen:

Once you have the application installed, launch the application.

The application is available for Linux, macOS, and Windows.

Install the nRF Connect desktop application from this link.Make sure you have the nRF52840 USB dongle connected to your computer.Installing the nRF Connect and Bluetooth Low Energy Applications The GATT can be customized with SIG-adopted services and characteristics or your own custom services and characteristics. As a BLE peripheral that advertises, allows connections, and exposes a GATT server.As a BLE central device that can discover advertising devices (broadcasters and peripherals).The Bluetooth Low Energy supports two modes of operation:

The different applications that support the dongle will automatically prompt you to update the dongle with the appropriate firmware that allows the application to interface with the dongle.

Today we will be focusing on using the Bluetooth Low Energy application.

nRF Cloud Gateway application (experimental).

As of the writing of this tutorial, the applications included in the desktop nRF Connect app are: It started out as a simple application but is now becoming the single hub for all desktop-based nRF applications. The nRF Connect application on the desktop supports a few applications (with more being added continuously). NRF Connect Bluetooth Low Energy application

Prototyping BLE apps on the nRF52840 USB Dongle (Part A).

If you’re interested in buying it, check out this page. More info on the dongle can be found at the Nordic InfoCentral documentation website here: nRF52840 USB dongle. In an upcoming post, we will go over how to use the dongle to run your own custom BLE application. In today’s blog post, we will cover how to use the dongle for running the Bluetooth Low Energy nRF Connect application as a central or a peripheral. When this feature becomes available, this low-cost dongle will serve as a great sniffer especially for capturing Bluetooth 5 BLE traffic including long-range mode (Coded PHY), high-speed mode (2M PHY), and extended advertisements packets. Also, as of the time of this tutorial, the nRF Sniffer application does not support the nRF52840 dongle, but this is inevitable to change. Keep in mind that the dongle does not have debug capabilities, but rather only supports programming or communicating via the USB port. These include Bluetooth Low Energy, Bluetooth mesh, Thread, ZigBee, 802.15.4, ANT and 2.4GHz proprietary applications.

As a development kit that can run your own custom applications or the sample applications provided with the nRF52 SDK.

As a dongle that enables nRF Connect PC applications such as the Bluetooth Low Energy application (central and peripheral emulator), the nRF Cloud Gateway application, and the RSSI Viewer application.

The dongle can be used in two main use cases: The nRF52840 dongle is a compact USB dongle that’s based on the nRF52840 chipset from Nordic Semiconductor. The dongle costs only $10 and can serve as a great development kit with a few I/O peripherals including one button, two LEDs (one green, one RGB), and 15 GPIO pins. Take for example the new nRF52840 USB dongle. When it comes to Bluetooth Low Energy modules, chipsets and development kits, prices are only getting lower.
