Now that a couple folks have verified the workaround, here it is:
sudo defaults write /Library/Preferences/com.apple.airport.bt.plist bluetoothCoexMgmt Hybrid
Then you need to reboot. I've tried and thus far failed to find a way to make this take effect without a reboot.
Background: after a lot of snooping and head scratching, here's what I found: the issue here seems to be that the system isn't using the same Bluetooth/Airport coexistance mode for BLE as it uses for BT Classic. One tell tale sign: if you have any BT Classic devices connected and active, the bug won't repro (neither for the Classic device nor any connected BLE device). The moment the Classic device disconnects, the bug repros (ie all the BLE connections are also dropped).
Further, I was able to find reference in the symbol table of an airport configd agent to an override setting for the coexistance mode. If you set the mode manually as above to 'hybrid' (the same mode that is usually invoked when a classic device is connected), the bug no longer repros.
Hope this is helpful. Best,
Will Henderson

If anyone is still hitting issues with 2.4ghz, please contact me off the list. I think I have a fix, would like to test it with a few others before I email the list and update the bug =).

As the developer of a Mac BLE app, I can verify this statement =). Also, only 2.4Ghz networks cause interference, so if you can connect to a 5Ghz network instead you will be OK.
I've got a bug on this (#13785322), but please file another! Always helps Apple to know more symptoms, more ways to repro and that more folks are hitting it.
