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/ […]
Smart Sensor Devices was awarded the Nordic Growth Company award from UC for success in the financial year 2019/2020. The company is doing steady and robust development and growth. The award was given for efforts during the previous financial year. The company sees a continued positive development and sales have increased compared with the previous […]
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 […]
Smart Sensor Devices is announcing a firmware update v2.0.0 for Bleuio and Smart USB dongle 2.0. We invite all the users to apply the updated firmware. The new firmware will be available to download on 26th March 2021, at https://www.bleuio.com/getting_started/docs/firmware/ Improvments: You can now connect with up to 8 devices at the same time. And 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 […]
