Occasional motion update problems with MetaWear

We are experiencing occasional problems where an individual sensor will stop being able to subscribe to motion updates with our iOS app.  Once the data gets into this state, we have to completely uninstall and reinstall our app in order for it to work again.   We do get an error message back when we try to start motion notifications:   Error Operation requires a client callback to have been registered. requesting playback queue.   Uninstalling the app does solve the problem, but we don't want to have to ask our users to have to uninstall and reinstall our app.


  • Unfortunately that is not an error message produced by the MetaWear SDK.  Do you have addition details (any surrounding information) about that error message?  You might try to reproduce it without using the MetaWear SDK to try and isolate that specific error.
