Network modeling of Bluetooth LE Auracast™ broadcast, multistream, and unicast audio

Bluetooth® Toolbox features and reference examples enable network modeling of the next generation of Bluetooth audio called low energy (LE) Audio.

Use the Bluetooth LE Audio modeling capabilities of the toolbox to:

  • Configure broadcast isochronous group (BIG) and connected isochronous group (CIG) parameters at Bluetooth LE audio transmitter and receiver nodes.

  • Simulate and visualize Auracast broadcast audio by using low complexity communication codec (LC3) encoded data bytes of an audio file.

  • Simulate and analyze how WLAN interference impacts an audio network using the BIG and multistream audio with the CIG.

  • Create, configure, and simulate a residential scenario and estimate the PDR of Bluetooth LE Auracast broadcast audio streams.

  • Simulate Bluetooth audio in a basic rate/enhanced data rate (BR/EDR) piconet by using synchronous connection-oriented (SCO) logical transport and asynchronous connection-oriented (ACL) logical transport.

Figure showing a Bluetooth LE Auracast broadcast audio sharing scenario. The scenario consists of an Auracast transmitter communicating with four Auracast receivers in the presence of WLAN signal interference.
