@millions-hair-24956 Hi I am using Flutter for app development. My agent is successfuly working and agent is deployed on server using python but my prompt like how sgent will behave is set on python.......in flutter I am connecting through a unique room can I sent prompt like how my user is bahaving to room so I can get Agent answer accordingly
g
To send a prompt from your Flutter app to the agent, you can use the
publishData
method to send custom data packets to the room. This allows you to send user-specific information or prompts that the agent can use to adjust its behavior. According to the LiveKit documentation, you can publish data messages to other participants in the same room using
LocalParticipant.publishData
. Here's a basic example of how you might implement this in Flutter:
Copy code
import 'package:livekit_client/livekit_client.dart';

final room = await LiveKitClient.connect(url, token);
final data = {
  'type': 'user_prompt',
  'prompt': 'User is behaving in a specific way',
};

await room.localParticipant.publishData(
  Uint8List.fromList(utf8.encode(json.encode(data))),
  reliable: true,
  topic: 'user_behavior',
);
This code sends a JSON-encoded message to the room, which the agent can then interpret and respond to accordingly. Would you like more detailed guidance on this process?

After connection I am doing this but its not resposnding me HI
Copy code
static setNewContext() {
  print("sent prompt");
  final data = {
    'type': 'user_prompt',
    'prompt': 'Say Hi, and start the user onboarding',
  };

  activeRoom!.localParticipant?.publishData(
    Uint8List.fromList(utf8.encode(json.encode(data))),
    reliable: true,
    topic: 'user_behavior',
  );
}

It seems likely that the issue might be related to how the agent is set up to handle the data messages. The agent needs to be listening for data messages with the specified topic and then act upon receiving them. Based on the LiveKit documentation, ensure that your agent is correctly set up to handle incoming data messages. Here’s a general approach to ensure the agent processes the data: 1. Agent Setup: Ensure your agent is listening for data messages with the topic 'user_behavior'. The agent should have an event handler for data messages that checks the topic and processes the message accordingly. 2. Data Handling: In your agent's code, you should have something like this:
Copy code
@ctx.room.on("data_received")
async def on_data_received(data_packet):
    message = json.loads(data_packet.data.decode('utf-8'))
    if message['type'] == 'user_prompt':
        prompt = message['prompt']
        # Process the prompt, e.g., make the agent say "Hi"
        await agent.say(prompt)
3. Debugging: Ensure that the data is being sent correctly from the Flutter app and that the agent is connected to the room and ready to receive messages. Would you like more detailed guidance on setting up the agent to handle these messages?

To ensure your agent responds to the data message sent from your Flutter app, you need to set up the agent to listen for data messages and process them accordingly. Here's how you can implement this in Python: 1. Ensure the Agent Listens for Data Messages: Your agent should have an event handler to listen for data messages with the specified topic. 2. Process the Data Message: Once the message is received, the agent should process the prompt and respond accordingly. Here's an example of how you might set this up in Python:
Copy code
import asyncio
import json
from livekit import rtc

async def handle_data_received(data_packet, ctx, agent):
    try:
        # Decode the data from the DataPacket
        message = json.loads(data_packet.data.decode('utf-8'))
        if message['type'] == 'user_prompt':
            prompt = message['prompt']
            # Make the agent say the prompt
            await agent.say(prompt)
    except Exception as e:
        print(f"Error handling data received: {str(e)}")

async def entrypoint(ctx):
    await ctx.connect(auto_subscribe=rtc.AutoSubscribe.AUDIO_ONLY)
    participant = await ctx.wait_for_participant()

    # Initialize your agent here
    agent = YourAgentClass()

    # Register data received handler
    ctx.room.on("data_received", lambda dp: asyncio.create_task(handle_data_received(dp, ctx, agent)))

    # Keep the connection alive
    while True:
        await asyncio.sleep(1)

# Run the agent
if __name__ == "__main__":
    from livekit.agents import cli, WorkerOptions
    cli.run_app(WorkerOptions(entrypoint_fnc=entrypoint))
Key Points: - Data Handling: The
handle_data_received
function decodes the incoming data packet and checks if it contains a
user_prompt
. If it does, it makes the agent say the prompt. - Agent Initialization: Ensure your agent is properly initialized and capable of responding to the
say
method. - Event Registration: The
ctx.room.on("data_received", ...)
line registers the handler to listen for data messages. Make sure your agent is connected to the same room and is ready to receive messages. If you need more detailed guidance, feel free to ask!
