I'm glad you're exploring how to send data from your Python-based LiveKit agent to a React Native mobile client! You can achieve this smoothly using LiveKit's real-time data communication features like Remote Procedure Calls (RPCs) or data messages. Let me walk you through it step-by-step. 1. Sending Data from the Agent (Python):

await ctx.room.local_participant.perform_rpc(
    destination_identity=client_participant.identity,
    method="nutrition.update",
    payload=json.dumps({
        'foods': foods,
        'totals': totals,
        'date': today_start.date().isoformat()
    })
)

This code sends a JSON payload to the client under the method name "nutrition.update". It’s a neat way to keep your client updated in real-time. 2. Receiving Data on the Client (React Native):

const { send } = useDataChannel((dataMessage: ReceivedDataMessage<string>) => {
  let decoder = new TextDecoder('utf-8');
  let message = decoder.decode(dataMessage.payload);
  let title = 'Received Message';
  if (dataMessage.from != null) {
    title = 'Received Message from ' + dataMessage.from?.identity;
  }
  Toast.show({
    type: 'success',
    text1: title,
    text2: message,
  });
});

Here, your client listens for incoming data messages and shows them in a toast notification—making sure you never miss an update. 3. Optional: Sending Data via Backend:

await roomService.sendData(roomName, new Uint8Array(data), kind, options);

This is another way to send data to all participants in the room, which might come in handy depending on your use case. To get you started, I recommend checking out these helpful starter projects: • Agent Starter (Python) • Mobile Starter (React Native) Just a quick tip—make sure both your agent and client are connected to the same LiveKit room and properly authenticated.
