tvOS Refuses to Connect Devices Over BLE

Summary:
To work around the tvOS Bluetooth limitation of 2 simultaneous connections we've adopted a Restful model where devices advertise services for data that they need, then the Apple TV connects to them and sends this data, and finally it disconnects and the iOS device stops advertising that service. The Apple TV is acting as a central and the iOS devices are acting as peripherals.
After a number of these short connections (between ~30 and 1200) the Apple TV continues to discover the iOS devices but always fails to connect to them, giving error code 0 ("Unknown error"). Fixing this requires a Bluetooth power cycle, which we are unable to do since the Apple TV does not allow you to turnoff bluetooth, so we are forced to perform a device restart. When bluetooth gets into this state, direct pairing with new accessories still appears to work, but any connections we attempt though CoreBluetooth within our app result in that error 0. If we see BTServer crash and respawn, bluetooth works for a larger number of connections (BTServer crashed 4 times when we reached 1200 connections without freezing up BLE).
To fix this issue we've tried:
-limiting the central to 1 connection at a time
-stopping scanning for peripherals when the maximum number of concurrent connections is reached (or when connecting a device will cause it to be reached)
-Adding a long delay between the disconnection of the last device (from didDisconnectPeripheral) and when the next device is allowed to connect [attempted with both a 1 device and 2 simultaneous device connection limit]
-Adding a timeout on device connections to close open connections with devices that have been connected for longer than 20 seconds
Steps to Reproduce:
Create a central (Apple TV) /peripheral (iOS) setup where the central searches for devices advertising certain services & characteristics, connects to them, discovers services on them, then as services are found discovers characteristics, then as characteristics are found the central subscribes to any that are readable, then upon learning of this subscription the peripheral writes data to that characteristic, and the central writes back a response to another characteristic. After this cancelPeripheralConnection is called with the peripheral as a parameter and the device is disconnected. Upon getting the response from the server the peripheral should stop advertising the service and characteristic. Repeating this advertisement from the peripheral and going through the connection -> send data -> disconnection phases will eventually lead to a reproduction of this problem.
Expected Results:
Peripheral connects to central
Actual Results:
Peripheral fails to connect to central with error 0, "unknown error"
Version:
tvOS 9.1.1 (13U717) - Apple TV; iOS 9.1-9.2.1 - Various iPhones and 4th gen iPod Touches; XCode Version 7.2 (7C68)
Notes:
When BTServer crashes (which helps us avoid this issue for a few more connections) we see a log that looks like the one in the attached file.
Configuration:
iPhone 6, 6s, 6+, iPad Air 2, iPod Touch 4th Gen, Apple TV 4
