You can set a timeout after

ctx.connect()

to detect if a user participant does not join within a certain period by combining

ctx.wait_for_participant()

with a timeout mechanism. For example, in Python using LiveKit Agents, you can use

asyncio.wait_for()

to wrap `ctx.wait_for_participant()`:

async def entrypoint(ctx: JobContext):
    await ctx.connect(auto_subscribe=agents.AutoSubscribe.AUDIO_ONLY)
    try:
        await asyncio.wait_for(ctx.wait_for_participant(), timeout=30.0)
        <http://logger.info|logger.info>("Participant connected successfully")
    except asyncio.TimeoutError:
        logger.warning("No participant joined within 30 seconds")
        await ctx.room.disconnect()
        return

This approach will raise a

TimeoutError

if no participant joins within the specified period (e.g., 30 seconds), allowing you to handle the timeout as needed. The same pattern can be applied in Node.js using

Promise.race()

with the equivalent

waitForParticipant()

method. Sources: examples/rpc.py | examples/rpc/index.ts | complex-agents/ivr-agent/agent.py | JobContext | LiveKit Agents
