Multinode communication in Bluetooth piconet

Bluetooth® Toolbox enables you to perform multinode communication in a Bluetooth piconet by using the protocol data units (PDUs) according to Bluetooth 5.3.

Use the features and reference examples to:

  • Generate and decode Bluetooth low energy (LE) link layer (LL), the logical link control and adaptation protocol (L2CAP), the generic access profile (GAP), and the attribute protocol (ATT) layer PDUs.

  • Create a Bluetooth piconet and evaluate the performance of the Bluetooth scheduler by implementing multiple applications with different quality-of-service (QoS) requirements.

  • Model Bluetooth LE devices with the Heart Rate Profile using the Generic ATT client-server scenario.

  • Export Bluetooth LE LL packets to packet capture (PCAP) and packet capture next generation (PCAPNG) files for network analysis.
