how reliable is SendDataRequest if i set kind=DataPacketKind.KIND_RELIABLE? WHat percentage of the time does it fail

Thanks for reaching out, Drew. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

Is there an easy way for one agent to send an ack to another telling it that it received the data sent to the troom

Hey there! If you want to send an acknowledgment from one agent to another in LiveKit after receiving data in a room, you can use the Remote Procedure Call (RPC) mechanism. Let me walk you through how it works: 1. Initiate an RPC Call: You can use the

performRpc

method on the

LocalParticipant

to send a request to another participant. Here’s a Swift example:

let response = try await localParticipant.performRpc(
    destinationIdentity: anotherAgentIdentity,
    method: "confirmReceipt",
    payload: "Data received",
    responseTimeout: 10
)

1. Send an Acknowledgment: The person receiving the request can send back an acknowledgment using the

publishRpcAck

method. Here’s how you’d do it in Android:

localParticipant.publishRpcAck(
    destinationIdentity = senderIdentity,
    requestId = requestId
)

1. Handle the Acknowledgment: Don’t forget to set up handlers to process incoming acknowledgments. Here’s an example in Flutter:

void handleIncomingRpcAck(String requestId) {
    // Handle the acknowledgment
}

Using this approach helps keep communication smooth and reliable between agents in LiveKit. If you have any questions or need a hand with this, just let me know!

Do the two agents have to be in the same room? Can I do this across two different rooms?

LiveKit's RPC feature is built to work within a single room, so everyone in that room can chat and send acknowledgments to each other. However, RPC calls and acknowledgments don’t work across different rooms. If you want to connect participants in different rooms, you’ll need to set up a solution at the application level, outside of what LiveKit’s RPC offers. I’m here if you want to chat more about how to make that happen! Sources: Realtime data | LiveKit Docs | Sources/LiveKit/Core/Room+EngineDelegate.swift
