Adding interference to Bluetooth LE Audio stream
coreBT2LE-IMP is an extension software for the call quality measurement frontend labCORE. It can interfere with the audio packets of Bluetooth LE Audio streams, enabling testing of concealment errors in devices equipped with Bluetooth LE Audio. It allows for the evaluation of the robustness of Bluetooth LE Audio devices such as headsets, headphones, and speakers. It is available for unicast point-to-point streams and Auracast broadcast audio streams.

Applications/Examples of results
Performance and Robustness Evaluation of Bluetooth LE Audio Devices Users can set the probability and temporal correlation of packet failures in ACQUA, causing disruptions in the transmission quality of Bluetooth LE Audio streams. The occurrence of failures is initiated by the labCORE Bluetooth encoder sending packets containing invalid data. When the affected packets are received, the decoder of the device under test activates packet loss concealment (PLC) to achieve a stable, uninterrupted audio stream.
