constructor

new LlrpManager(options?: LlrpManagerOptions): LlrpManager
Parameters
- options: LlrpManagerOptions = {}
Returns LlrpManager
Overrides LlrpEndpoint.constructor
- Defined in src/protocols/rdmnet/llrp-transport.ts:124

Methods

close

close(): void
Returns void
Inherited from LlrpEndpoint.close
- Defined in src/protocols/rdmnet/llrp-transport.ts:110

discoverTargets

discoverTargets(): Promise<LlrpDiscoveredTarget[]>
Runs full-range LLRP discovery: repeatedly probes (narrowing/advancing the UID range and excluding already-known UIDs) until three consecutive rounds yield nothing new across the whole 48-bit UID space. Resolves with every Target discovered.

Returns Promise<LlrpDiscoveredTarget[]>
- Defined in src/protocols/rdmnet/llrp-transport.ts:139

getCid

getCid(): Buffer
Returns this endpoint's CID.

Returns Buffer
Inherited from LlrpEndpoint.getCid
- Defined in src/protocols/rdmnet/llrp-transport.ts:106

probeOnce

probeOnce(
    lower: UID,
    upper: UID,
    knownUids?: UID[],
): Promise<LlrpDiscoveredTarget[]>
Sends one Probe Request for [lower, upper] (excluding knownUids) and collects replies for LLRP_TIMEOUT_MS.
Parameters
- lower: UID
- upper: UID
- knownUids: UID[] = []
Returns Promise<LlrpDiscoveredTarget[]>
- Defined in src/protocols/rdmnet/llrp-transport.ts:191

sendRdmCommand

sendRdmCommand(destinationCid: Buffer, rdmFrame: Buffer): Promise<number>
Sends a raw RDM command (frame starting with 0xCC) to one Target.
Parameters
- destinationCid: Buffer
- rdmFrame: Buffer
Returns Promise<number>
- Defined in src/protocols/rdmnet/llrp-transport.ts:233

start

start(): Promise<void>
Joins the response multicast group so probe replies can be received.

Returns Promise<void>
- Defined in src/protocols/rdmnet/llrp-transport.ts:129

waitForRdmResponse

waitForRdmResponse(
transactionNumber: number,
timeoutMs?: number,
): Promise<Buffer<ArrayBufferLike>>
Waits for one RDM response (frame starting with 0xCC) correlated by transaction number.
Parameters
- transactionNumber: number
- timeoutMs: number = LLRP_TIMEOUT_MS
Returns Promise<Buffer<ArrayBufferLike>>
- Defined in src/protocols/rdmnet/llrp-transport.ts:243
