Bluetooth System-Level Simulation

Entry point for all Bluetooth system-level simulation. All Bluetooth simulations use sim = wirelessNetworkSimulator.init and follow the workflow defined in matlab-simulate-wireless-network (simulator init, traffic, mobility, instrumentation, addNodes, run).

When to Use

BLE ACL point-to-point or star network connections
LE Audio unicast with CIS/CIG (stereo speakers, hearing aids)
BLE GAP connection establishment (advertising, scanning, connection timing)
Classic BR/EDR piconets with ACL data or SCO voice
BLE + BR/EDR coexistence with adaptive frequency hopping
Any simulation using bluetoothLENode, bluetoothNode

When Not to Use

Non-Bluetooth wireless simulations (use matlab-simulate-wireless-network instead)
PHY-layer or link level Bluetooth waveform generation, receiver analysis or BER analysis
Generic simulator setup, traffic models, or mobility (use matlab-simulate-wireless-network)

Scenario → Reference Routing

Scenario	Reference
BLE realistic connection setup (advertising, scanning, GAP)	`references/ble-gap-connection.md`
BLE point-to-point data, star network, ACL connections	`references/ble-connection.md`
LE Audio unicast (stereo speakers, hearing aids, CIS/CIG)	`references/ble-cis.md`

BLE + BR/EDR coexistence, adaptive frequency hopping	`references/bluetooth-coexistence.md`
Capture and visualization (PCAP, IQ, event tracing, traffic viewer)	See `matlab-simulate-wireless-network` skill

Node Roles

BLE (ACL, CIS): bluetoothLENode("central"), bluetoothLENode("peripheral")
BR/EDR: bluetoothNode("central"), bluetoothNode("peripheral") — max 7 peripherals per central

Traffic Attachment Rules

addTrafficSource(sourceNode, traffic, ...):

ACL/CIS/BR/EDR: DestinationNode=peer required. CIS also needs CISConfig=cfgCISOut.
BR/EDR SCO: No traffic call — implicit via SCOPacketType in connection config.

kpi() Availability

Topology	`"throughput"`	`"latency"`	`"PLR"` / `"PDR"`	Layer
BLE ACL	LL only	App only	Both LL and App	`"LL"` or `"App"`
BLE CIS	LL only	App only	Both LL and App	`"LL"` or `"App"`
BR/EDR	Baseband	—	Baseband	`"Baseband"`

Connection/Configuration Setup

Topology	Config Object	Function	Notes
BLE ACL	`bluetoothLEConnectionConfig`	`configureConnection(cfg, central, peripheral)`	Per-peripheral in loop; unique `AccessAddress` per connection
BLE CIS	`bluetoothLEConnectionConfig` + `bluetoothLECISConfig`	`[~, cfgCISOut] = configureConnection(cfg, central, peripheral, CISConfig=cfgCIS)`	Pass `cfgCISOut` to `addTrafficSource(..., CISConfig=cfgCISOut)`
BR/EDR	`bluetoothConnectionConfig`	`configureConnection(cfg, central, peripherals)`	Single call with vector of peripherals

Common Mistakes

bluetoothNode for BLE (or vice versa): BR/EDR = bluetoothNode, BLE = bluetoothLENode
Wrong kpi Layer: BLE throughput → "LL", BLE latency → "App", BR/EDR → "Baseband" only
Properties locked after run(): Node/connection properties cannot change mid-sim. Use updateChannelList for mid-sim channel updates.
configureConnection with peripheral vector for BLE: Must call per-peripheral in loop (BR/EDR accepts vector)
Unique AccessAddress per connection: Each BLE connection on same central needs different AccessAddress
DataRate in Kbps: DataRate=100 means 100 Kbps, not 100 bps
GeneratePacket=true is not valid: Not applicable for network-level simulation. Use OnTime=Inf for continuous traffic.

BLE CIS (Connected Isochronous Stream) Simulation

Simulate LE Audio using Connected Isochronous Streams. CIS provides time-bounded, reliable isochronous data delivery for use cases like stereo speakers, hearing aids, and multi-channel audio.

When to Use

Simulating LE Audio with multiple speakers (stereo, surround)
Configuring CIS timing for LC3 codec alignment
Testing latency requirements for audio (<20ms)
Multi-peripheral CIG (Connected Isochronous Group) scheduling

CIS End-to-End Flow (3 Steps)

% Step 1: Create CIS config
cfgCIS = bluetoothLECISConfig(ISOInterval=0.02, MaxPDU=120, NumSubevents=2, BurstNumber=[1 0]);

% Step 2: configureConnection returns UPDATED CIS config (capture 2nd output)
[~, cfgCISOut] = configureConnection(cfgConn, central, peripheral, CISConfig=cfgCIS);

% Step 3: Pass returned cfgCISOut to addTrafficSource
addTrafficSource(central, traffic, DestinationNode=peripheral, CISConfig=cfgCISOut);

If struggling with CIS setup, refer to openExample("bluetooth/BLEMultistreamAudioExample") for a working reference.

Quick-Start: Pick a Template

Select the template matching your use case. All values are pre-validated.

Use Case	NumPerip	PHY	MaxPDU	NSE	ISO (s)	CI (s)	AP (s)
Stereo TWS (2 earbuds)	2	LE2M	120	2	0.02	0.04	0.005
Hearing Aid (mono)	1	LE2M	100	2	0.02	0.02	0.005
Hearing Aid (bidir)	1	LE2M	[100 40]	2	0.02	0.02	0.005
4-Speaker Surround	4	LE2M	120	2	0.02	0.08	0.005
Stereo LE1M (fallback)	2	LE1M	120	1	0.02	0.04	0.005
Low-Latency Stereo	2	LE2M	120	1	0.01	0.02	0.005

Formulas (only needed for non-standard configurations):

ConnectionInterval = NumPeripherals × ISOInterval
ConnectionOffset(i) = (i-1) × ISOInterval
ISOInterval >= ActivePeriod + NumPeripherals × NSE × SubeventLength
ISOInterval must be a multiple of 1.25ms, range [5ms, 4s]

Complete Pattern: Stereo TWS

sim = wirelessNetworkSimulator.init;

central = bluetoothLENode("central", Position=[0 0 0]);
peripherals = [bluetoothLENode("peripheral", Position=[-1 1 0]), ...
               bluetoothLENode("peripheral", Position=[1 1 0])];

cfgCIS = bluetoothLECISConfig(ISOInterval=0.02, MaxPDU=120, ...
    NumSubevents=2, BurstNumber=[1 0], FlushTimeout=[2 1]);

for i = 1:2
    cfgConn = bluetoothLEConnectionConfig( ...
        ConnectionInterval=0.04, ...
        ActivePeriod=0.005, ...
        ConnectionOffset=(i-1)*0.02, ...
        AccessAddress=sprintf("5DA4427%d", i-1), ...
        PHYMode="LE2M", MaxPDU=120);

    [~, cfgCISOut] = configureConnection(cfgConn, central, peripherals(i), CISConfig=cfgCIS);

    traffic = networkTrafficOnOff(DataRate=48, PacketSize=120, OnTime=Inf);
    addTrafficSource(central, traffic, DestinationNode=peripherals(i), CISConfig=cfgCISOut);
end

addNodes(sim, [central; peripherals(:)]);
run(sim, 0.5);

Complete Pattern: Hearing Aid Bidirectional

sim = wirelessNetworkSimulator.init;

central = bluetoothLENode("central", Position=[0 0 0]);
peripheral = bluetoothLENode("peripheral", Position=[0.1 0 0]);

cfgCIS = bluetoothLECISConfig(ISOInterval=0.02, MaxPDU=[100 40], ...
    NumSubevents=2, BurstNumber=[1 1], FlushTimeout=[2 2]);

cfgConn = bluetoothLEConnectionConfig( ...
    ConnectionInterval=0.02, ActivePeriod=0.005, ...
    AccessAddress="5DA44270", PHYMode="LE2M", MaxPDU=[100 40]);

[~, cfgCISOut] = configureConnection(cfgConn, central, peripheral, CISConfig=cfgCIS);

trafficDL = networkTrafficOnOff(DataRate=40, PacketSize=100, OnTime=Inf);
addTrafficSource(central, trafficDL, DestinationNode=peripheral, CISConfig=cfgCISOut);

trafficUL = networkTrafficOnOff(DataRate=16, PacketSize=40, OnTime=Inf);
addTrafficSource(peripheral, trafficUL, DestinationNode=central, CISConfig=cfgCISOut);

addNodes(sim, [central, peripheral]);
run(sim, 0.5);

Key Rules

Rule 1: Use RETURNED CIS Config for Traffic

configureConnection returns an updated CIS config with computed read-only fields. You MUST use this returned config:

[~, cfgCISOut] = configureConnection(cfgConn, central, peripheral, CISConfig=cfgCIS);
addTrafficSource(central, traffic, DestinationNode=peripheral, CISConfig=cfgCISOut);

Rule 2: ISOInterval = ConnectionInterval / NumPeripherals (STRICT)

This is enforced at runtime. Use the template table or formula:

ConnectionInterval = NumPeripherals × ISOInterval
Standard choice: ISOInterval = 0.02 (20ms, matches LC3 frame interval)

Rule 3: ActivePeriod = 0.005 (safe default)

Use ActivePeriod = 0.005 for all CIS simulations. This satisfies the minimum for LE1M and LE2M with any MaxPDU ≤ 251.

Rule 4: ConnectionOffset Staggering

Each peripheral's offset = (i-1) × ISOInterval:

cfgConn.ConnectionOffset = (i-1) * cfgCIS.ISOInterval;

Rule 5: Parameter Name is `CISConfig`

Always use CISConfig=... (not CfgCIS, CISCfg, or ISOConfig).

Statistics / KPI

kpi(): Throughput at "LL", latency at "App", PLR/PDR at both layers.

statistics(node): App layer has ReceivedPackets/Bytes, AveragePacketLatency. LL layer CIS sub-struct: CISStatistics.CISID, TransmittedPackets, ReceivedPackets, RetransmittedPackets, AcknowledgedPackets.

CIS Config Properties

Property	Range	Default	Notes
ISOInterval	[5ms, 4s]	0.02	Multiple of 1.25ms
NumSubevents	[1, 31]	1	Retransmission opportunities
SubInterval	[0.4ms, 4s]	auto	Time between subevents
BurstNumber	[0, 15]	1	Scalar or [C→P, P→C]
MaxPDU	[0, 251]	251	Scalar or [C→P, P→C]
FlushTimeout	[1, 255]	1	Scalar or [C→P, P→C]
CISArrangement	seq/interl	"sequential"	Subevent layout

Read-only after configureConnection: AccessAddress, CISID, CISOffset.
