Acceleration and Gyroscope events don't appear

Dear Niklas,

Sorry, I've completely rewritten my question here. Previously it was different, but formulated in a wrong way. Hopefully it didn't bother you)

I successfully run your example files, but I face an issue during the use of Listener class in my application. I'm making a PyQt app that visualizes the EMG and IMU data in real time. I've written my own listener, based on your example, that puts all the data into a Queue shared between the listener and parent widget. The problem is that I don't receive orientation events at all. Let's take this code for example:
def on_event(self, kind, event): print(kind)
When a listener with this code is created in main(), like in your example, it prints this:
...
EventType: emg
EventType: emg
EventType: emg
EventType: emg
EventType: orientation
...
in a repetitive way and I find it completely correct.

But when I create the same listener in my widget, it gives only :
...
EventType: emg
...

The listener class I use in both examples is the same. The difference is whether I create it in main() function or in my app's widget. Do you have some idea about this issue?
I do it on OSX El Capitan, armbands are up to date.

Thank you very much!

Update:
Briefly, orientation events don't appear when the hub object is run from a PyQt widget object. I followed the problem until wrapper() function in run() method of Hub class in ctyping.py. It doesn't receive events of type orientation at all. It does receive emg events if emg is enabled. If emg is disabled it receives no data events.
Seems to be a problem of SDK, but I haven't seen any issues on the developers forum. Still thanks if you have some information, but I understand that it's an SDK's problem.

Hi @ahkmadeus,

unfortunately I can't reproduce the issue here. I couldn't test it in a
PyQt environment yet, though.
It does sound really strange though. Sorry but I have no idea where this
could be coming from. :(

Hi @NiklasRosenstein

I fully understand this situation, never mind. If I find the way I'll tell you here.
Otherwise if you want I can help you to reproduce the problem. If you have OSX and anaconda installed, that will take 10 minutes. if you haven't, never mind, again.

Thanks!
