Acrylic have a new Windows-based Bluetooth LE Analyzer that can be used to check for and test Bluetooth devices. The application has a scanner showing the Bluetooth signal strength range (RSSI):
It also provides analysis using dynamic and customizable graphs showing RSSI (signal strength), signal distribution over time and approximate device distance. A BLE beacon viewer shows detailed information on Low Energy Bluetooth devices. The BLE Packet Analyzer explores Bluetooth packet contents:
There’s also an inventory system to keep track of your devices. The free version scans, detects iBeacons and visualises signal strength. The licensed version has the packet analyzer, inventory and advanced filtering.
MIT App Inventor is a cloud-based tool that allows you to build apps in the web browser. It provides a visual programming block-based environment allowing anyone, even children, to build fully functional apps for smartphones and tablets.
The first 50 registrants are being entered into a raffle to win 10 PIC-IoT boards and vouchers worth €10 and €25 for the Elektor Store.
Beacons provide a significant improvement in the sign in process, reducing administration and providing for a quicker and easier sign in using the Ostara app. 1300 Bluetooth Beacons have been installed that are used by over 10,000 engineers.
The system consists of two solar powered belisha pedestrian crossing beacons installed by John Sisk and Son Ltd as part of traffic management plan measures.
Each belisha beacon has a Bluetooth transmitter advertising iBeacon. This allows parameters such as the battery voltage, discharge current and the beacon’s unique ID (UID) to be obtained and controlled remotely using an app.
As real, physical events come back after the pandemic, systems like Aventri will become useful once again. Aventri is an app-based event and conference guide that increases engagement and provides real-time event performance insights.
iBeacons can be used to trigger an automated message when a user is in range of a booth or other conference location. They can also be used to implicitly measure foot traffic at particular points. It’s also possible to generate lists of who visited each booth.
The system involves a smart helmet worn by walking workers that picks up Bluetooth beacons attached to heavy equipment, vehicles or placed in dangerous zones. The aim is to prevent collisions between equipment and pedestrians in mines.
The bidirectional proximity warnings provide visual proximity alerts that reduce worker mental effort and stress and help to free the hands of workers to maintain work efficiency.
The system uses an Arduino Uno board with Bluetooth BLE module within the helmet. Visual warnings are provided using LED straps.
The use of Bluetooth for proximity safety warnings isn’t new. We have come across similar concepts in power stations and factories where fixed smart lights and/or apps, rather than smart-helmets, are used to improve proximity safety, particularly near blind corners or hazardous areas. We also have clients re-purposing social distancing beacons to provide for simpler systems that warn workers of proximity to vehicles.
