I am running a Flask application on a Raspberry Pi running on a uWSGI server. I am trying to implement a WebSocket protocol with Flask-socketIo combined with gevent & gevent-websocket as specified in the doc.
When I start the app with this line I got no issue, the data is sent to the client thru websocket as expected:
socketio.run(app, host='0.0.0.0', port=80, debug=True)
However if debug is set to False, the emit function is no longer working.
def updateSensorsState(sensor):
print "update"
socketio.emit('state', json.dumps(sensor))
In this case when I press a button updateSensorState(sensor) is called from a GPIO callback. I get update printed in the console and the emit function seems to hang there. If I press the button many time, once in a while the client will receive a queue of message many time later...
Any advice to help me what is going on with my code would be much apreciated.
Thank you.

Are you also using GPIO when you run in debug mode? I doubt gevent is compatible with that, whatever you do with hardware is likely blocking.

Yes I run the exact same code with the GPIO. It works in debug and hang when debug is set to False... I also tried with evenlet and same thing happend.

@Miguel If I runsocketio = SocketIO(app, async_mode='threading')and debug=False it also works with long polling.
