Thanks for reaching out, John. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
Hey there! To join another room using an access token and URL in LiveKit, the best way is to use the 
rtc.Room()
method. It’s designed to make real-time communication smooth and comes with handy features like adaptive streaming and automatic subscription. Here’s a quick guide on how to do it: 1. Generate an Access Token: You’ll want to create an access token with the right permissions using the LiveKit API. For example:
Copy code
token = (
    api.AccessToken()
    .with_identity("client-user")
    .with_name("Client User")
    .with_grants(
        api.VideoGrants(
            room_join=True,
            room="your-room-name",
        )
    )
    .to_jwt()
)
1. Connect to the Room: Then, use the 
rtc.Room()
class to connect with your URL and token like this:
Copy code
room = rtc.Room()
await room.connect(LIVEKIT_URL, token, options=rtc.RoomOptions(auto_subscribe=True))
This way is pretty straightforward and reliable—it takes care of connection management and event handling for you. Just a heads-up: the REST API is usually for server-side stuff like creating rooms or managing recordings, not for jumping into rooms in real-time. If you have any questions or want me to walk you through anything else, just give me a shout!
Hey there! That warning saying "The room connection was not established within 10 seconds after calling job_entry" usually pops up when the room connection takes longer than expected to get going. No worries though—here are some friendly steps to help you fix it: 1. Make sure 
job_ctx.connect()
is being called: Double-check that you’re calling 
job_ctx.connect()
right at the start of your job’s entrypoint to kick off the room connection:
Copy code
async def job_entry(job_ctx: JobContext) -> None:
    await job_ctx.connect()  # This sets up the room connection
    # Your job logic here
1. Handle shutdown properly: It’s important to call 
job_ctx.shutdown()
when cleaning up so disconnections happen smoothly:
Copy code
try:
    # Your job logic
finally:
    await job_ctx.shutdown("Completed")  # Make sure shutdown runs
1. Check your production setup: If you’re running this in production, make sure you have multiple servers per agent to avoid any single points of failure. Following LiveKit’s production deployment tips can really help here. 2. Keep an eye on connection state: You can monitor connection events to handle any disconnects or reconnects gracefully:
Copy code
room = job_ctx.room
room.on("disconnected", lambda: print("Room connection lost"))
1. Some troubleshooting tips: ◦ Take a look at your logs to see connection attempts and any errors. ◦ Make sure there aren’t any network hiccups or firewall blocks getting in the way. ◦ Check that your server has enough resources to handle the job. Hopefully, these tips get you back on track with a solid room connection. If you hit any snags or want to chat more about it, just let me know—I’m here to help!

Here's a handy code snippet to help you connect a client to a LiveKit room smoothly using `rtc.Room()`:
Here’s a handy code snippet to help you connect a client to a LiveKit room smoothly using `rtc.Room()`:
Let me walk you through how this process works in a bit more detail: 1. Generate an Access Token: Think of the access token as a secure pass that lets your client join a specific room. You create it using the LiveKit API, where you can set permissions and room details. Here’s a quick example:
Copy code
token = (
    api.AccessToken()
    .with_identity("client-user")  # Unique identifier for the client
    .with_name("Client User")      # Optional display name for the client
    .with_grants(
        api.VideoGrants(
            room_join=True,         # Permission to join the room
            room="your-room-name", # The specific room the client can join
        )
    )
    .to_jwt()                       # Converts the token to a JWT string
)
This token is created on the server side to keep things secure, and then you pass it along to the client so they can connect to the room. 1. Connect to the Room: Once you have that token, you’ll use the 
rtc.Room()
class to actually connect to the LiveKit server. Here’s how you do it:
Copy code
room = rtc.Room()
await room.connect(LIVEKIT_URL, token, options=rtc.RoomOptions(auto_subscribe=True))
Here’s what’s happening: • `rtc.Room()`: This creates a new room instance to manage your connection. • `room.connect()`: This connects you to the LiveKit server using your URL and token. • `options=rtc.RoomOptions(auto_subscribe=True)`: This makes sure you automatically subscribe to audio and video tracks as soon as you join. This approach is great because it takes care of managing the connection, retrying if something goes wrong, and handling events like new participants joining or track updates.

Hey there! I’ve put together some handy resources and examples to help you get started with generating access tokens and connecting to LiveKit rooms. Let’s dive in! Generating Access Tokens Access tokens are created using the LiveKit Server SDK. Here are some examples to guide you: Python Example:
Copy code
from livekit import api
import os

# Generate random room name and participant identity
room_name = f"my-room-{os.urandom(4).hex()}"
identity = "user1"

# Create an AccessToken with VideoGrants
token = api.AccessToken() \
    .with_identity(identity) \
    .with_name(identity) \
    .with_grants(api.VideoGrants(
        room_join=True,
        room=room_name,
    )).to_jwt()
Node.js Example:
Copy code
const { AccessToken } = require("livekit-server-sdk");

// Create an access token with VideoGrants
const at = new AccessToken(apiKey, apiSecret, {
  identity: username,
});
at.addGrant({
  roomJoin: true,
  room: roomName,
});
const token = await at.toJwt();
Connecting to a LiveKit Room Once you have your token, you can use the client SDK to connect. Here’s how: Python Example:
Copy code
from livekit import rtc

async def main():
    room = rtc.Room()
    @room.on("participant_connected")
    def on_participant_connected(participant: rtc.RemoteParticipant):
        print(f"Participant {participant.identity} connected")
        
    @room.on("track_subscribed")
    def on_track_subscribed(track: rtc.Track, 
                           publication: rtc.RemoteTrackPublication,
                           participant: rtc.RemoteParticipant):
        print(f"Subscribed to {track.kind} track from {participant.identity}")

    token = "yourGeneratedToken"  # From above
    ws_url = "<ws://localhost:7880>"
    await room.connect(ws_url, token)
    print("Connected to room")

asyncio.run(main())
Node.js Example:
Copy code
const room = new Room();
await room.connect("<ws://localhost:7880>", token);
