Introduction The BleuIO is Bluetooth low energy USB dongle that can be used to create new BLE 5.0 applications in the fastest and easiest way. The BleuIO comes with a bootloader that allows you to update the firmware or flash your own application to the dongle. This guide will show you how to get started with […]
The BleuIO comes with a bootloader to allow you to update the firmware or flash your own application to the dongle. To flash the dongle, you will need an image file containing the new firmware or your own application and a host USB loader application. You can download the latest firmware, and host USB loader […]
Distance to a Bluetooth device can be measured using RSSI value. The following script will help you locate nearby unique BLE devices within a selected range. This script scans for nearby unique Bluetooth devices within the given range using a well-known RSSI to distance formula. Requirments You need to have a BLE USB dongle BleuIO https://www.bleuio.com/ […]
Distance between Bluetooth devices can be measured using RSSI value. Using the script presented in this article will help us to get device distance using BleuIO. This script scans for nearby Bluetooth devices and get an approximation of the distance by using well known RSSI to distance formula. Requirments Instructions git clone https://github.com/smart-sensor-devices-ab/ble_distance_measure.git Go inside […]
This tutorial will show how to transfer files wirelessly over the Bluetooth Low Energy protocol. We will use two BleuIO dongles for this project—one for sending and another one for receiving. The sender dongle will be in central mode, while the receiver dongle will be in peripheral mode. We have already created two python scripts […]
Bluetooth low energy technology offers a suitable way of connecting smart devices.However, despite the convenience, you can bear witness that the range offered can be a little limiting. Sometimes the connection tends to drop or lag when you move a little further away from the device. Fortunately, it’s easy to overcome this range limitation with […]
This project will demonstrate how to easily create a mobile app to connect to BleuIO dongle and share data between them. At first, we will connect BleuIO dongle to our pc. We already created a simple mobile app for this project. All you need to clone this project and run the app on your mobile […]
Recently, Bluetooth Low Energy (BLE) has become one of the most popular wireless standards for IoT devices. Most applications are now using this technology to transfer sensitive information between devices. Therefore, designers looking to integrate BLE into their products should be aware of the BLE security features and limitations. The main security issues with the […]
In this article, we will see how to send BLE data to the cloud. Together with the BleuIO javascript library and BleuIO USB dongle, we will get BLE data from HibouAir. After getting the advertised data, we will pass it to a simple function that will give us an object with meaningful air quality data […]
Protection of private information is essential for every wireless low energy device, from fitness band to payment systems. Privacy mechanisms prevent devices from being tracked by untrusted devices. Secure communications keep data safe while also preventing unauthorized devices from injecting data to trigger the system’s unintended operation. In Bluetooth Low Energy (BLE), devices connected to […]
