Connection closes instantly with tvOS 18.4 (companion protocol) #2656
Description
Describe the bug
I have 2 AppleTV boxes : one on tvOS 18.3 and another with 18.4 beta.
The one with 18.4 beta raises a connection lost exception right after the connection (the other one works fine).
I paired the device with 2 protocols : companion and airplay. The disconnection is raised when using the companion protocol, (airplay is fine).
Edit : tested with python 3.12 and 3.13, on windows and a Ubuntu docker instance.
See the sample code below to reproduce it with the following steps
- Pair the Apple TV device with companion protocol using tvOS 18.4
- Connect to it with pyatv
- Subscribe to connection lost/closed events by implementing the
DeviceListenerinterface - The client will receive a lost connection event a few milliseconds later
class AppleTvClient(DeviceListener):
async def start_client():
self._atv = AppleTv(device=config, loop=_LOOP)
await self._atv.connect()
self._atv.listener = self
def connection_lost(self, _exception) -> None:
_LOG.exception("[%s] Lost connection %s", self.log_id, _exception)
def connection_closed(self) -> None:
_LOG.debug("[%s] Connection closed!", self.log_id)
