Towards Reliable BLE Communication in Industrial Applications

Bluetooth Low Energy (BLE) is becoming increasingly more popular to wirelessly connect devices to each other. This trend is not limited to consumer electronics, but can also be seen in harsh environments, such as automotive workshops and garages, where embedded devices need to communicate with a technician's laptop. AVL DiTEST ( is a Graz-based company creating such embedded measurement and diagnostic devices that are used in harsh environments.

In this project, we are working in cooperation with AVL DiTEST towards exchanging their current device-to-device communication with BLE.

To ensure a high user experience, it is essential that the BLE communication between embedded device and laptop works reliably and does not introduce significant communication delays. Furthermore, it is vital that the BLE communication between embedded device and laptop is compliant to the BLE specification to ensure interoperability .
