async with AioWebSocket(uri) as aws:
converse = aws.manipulator
message = b'AioWebSocket - Async WebSocket Client'
while True:
await converse.send(message)
print('{time}-Client send: {message}'
.format(time=datetime.now().strftime('%Y-%m-%d %H:%M:%S'), message=message))
The above code can not see an error when the socket is closed. need to call below code:
awati converse.writer.drain()

I think this code can add to send method
