Multinode Communication

Bluetooth^® Toolbox system-level simulation capabilities enable you to configure, simulate, and visualize multinode communication in Bluetooth basic rate/enhanced data rate (BR/EDR) and low energy (LE) piconets, LE Audio, and mesh networks. You can model communication links involving multiple nodes. The simulations function across a protocol stack that includes the physical layer (PHY), baseband layer or link layer (LL), network layer, transport layer, and application layer (APP). You can measure key performance indicators (KPIs) such as throughput, latency, packet delivery ratio (PDR), and packet loss ratio (PLR) at both the node and network levels to analyze the network or the effect of interference.

The toolbox provides you with these capabilities.

• Full PHY simulation with waveform generation and receiver decoding

• Interference modeling

• Custom channel model integration

• Application traffic pattern modeling using an On-Off network traffic model

• Node mobility support using random waypoint mobility model

• Running multiple independent simulations in parallel

• Multinode communication capabilities in Bluetooth BR/EDR and LE, which include:

  • Bluetooth LE piconet supporting asynchronous connection-oriented (ACL) connections with ACK/NACK, AFH, and the channel map update procedure

  • Bluetooth LE in 6 GHz supporting channel access mechanisms such as listen before talk (LBT), spectrum sensing based deferral (SSBD), and detect and avoid (DAA)

  • Bluetooth LE Auracast™ broadcast audio network with the broadcast isochronous group (BIG) and multistream audio with the connected isochronous group (CIG)

  • Bluetooth BR/EDR piconet supporting ACL (with ACK/NACK), synchronous connection-oriented (SCO) logical transports, adaptive frequency hopping (AFH), channel classification, the channel map update procedure, and scheduling

  • Interframe space (IFS) configuration in a connected isochronous stream (CIS) subevent and an ACL connection event

  • Bluetooth mesh network over an advertising bearer, consisting of relay, low power, and friend nodes

  • Periodic and legacy advertising within a Bluetooth LE network involving multiple broadcasters and observers

  • Generation and decoding of protocol data units (PDUs)

  • Logging and analysis capabilities such as node- and network-level statistics, visualization of node state transitions and channel occupancy, logging of packets into packet capture (PCAP) or PCAP next generation (PCAPNG) files, and logging received Bluetooth waveforms as in-phase and quadrature (IQ) samples
