Im using the External Accessories framework to read accelerometer and gyroscope data from the bluetooth device. The frequency of the data stream is about 200 Hz. However when the iOS device receives a push notification (ex an iMessage) there is some data loss. Any ideas why this is happening and what is causing the data loss? An interesting observation that I made: With the Xcode debugger I put a breakpoint in my code while data is streaming from the bluetooth device to pause execution of my application. When I resume execution 5 seconds later, I still receive the data that was being streamed while the app was suspended! Is this because iOS buffers the data and waits for my app to come back to life before calling the stream handleEvent delegate? Here is how I am communicating with the bluetooth device: https://developer.apple.com/library/content/featuredarticles /ExternalAccessoryPT/Articles/Connecting.html _______________________________________________ Do not post admin requests to the list.
