Product:iOS + SDK Product Version:iOS 11.0 (15A5278f)
Classification: Reproducible:yes
 
Area:
External Accessory Framework

Summary:
As of iOS 11, we never receive a EAAccessoryDidConnectNotification via the [NSNotificationCenter defaultCenter] (even after invoking [EAAccessoryManager.sharedAccessoryManager registerForLocalNotifications]). This was not the behavior as of iOS 10 and below. This prevents our application from connecting to our device.

Steps to Reproduce:
Pair our Bluetooth device via the Settings app and wait for callbacks via the EAAccessory notification methods.

Expected Results:
We expect to receive an EAAccessoryDidConnectNotification from the -[NSNotificationCenter defaultCenter] after invoking [EAAccessoryManager.sharedAccessoryManager registerForLocalNotifications].

This was the behavior as of iOS 10 and below. This prevents our application from connecting to our device.

Observed Results:
No EAAccessoryDidConnectNotification notifications are sent via the -[NSNotificationCenter defaultCenter].

The device is shown as "Connected" via the system "Bluetooth" settings when this occurs. We have tried unpairing and re-pairing the device, but still have yet to receive any callbacks or notifications.
