gevent-socketio send message from thread
From this section of the documentation:
Sometimes the server needs to be the originator of a message. This can be useful to send a notification to clients of an event that originated in the server. The socketio.send() and socketio.emit() methods can be used to broadcast to all connected clients:
def some_function(): socketio.emit('some event', {'data': 42})This emit is not from from flask.ext.socketio import SocketIO, send, but instead called on your socketio variable from socketio = SocketIO(app). Had you done socketio_connection = SocketIO(app), then you'd be calling socketio_connection.emit() to broadcast your data.
