Hi eskimo, thanks for looking at this. I've also been having this crash for a year now. I've tested multiple things but as soon as I use registerForLocalNotifications, even if I don't subscribe to EAAccessoryDidConnect when my bluetooth accessory get disconnected when the app is running i'm getting this crash 80% of the time. I've attached a crash report, i've just redacted the bundle and app name. crasahreport.txt

I don't know why i didn't initially thought of sending a bug report .. Here's the bug number FB12831700 To clarify, that is exactly right. However i should specify that the apps while connected to the accessory is not listening for local notifications the whole time. For a specific flow we start the local notification registration, and then stop it when its done. During a normal use of the app (thus not in the specific flow) we are not seeing this crash.

Following on that, I too am interested in using the new Framework for my UI. I'm currently using an MFi EAAccessoryBrowser setup, is there no way to use the ExternalAccessory framework with AccessorySetupKit in a "streamlined" way ?
