[Zubersoft]

Each feature uses its own connection (otherwise you could get cross talk that could cause problems if they all shared a single connection). Your device probably has a limit on the number of simultaneous bluetooth connections (some devices have a limit as low as 3) which is why you encounter an error when trying to establish another one. That's just my guess based on your description. Synchronizing a library over bluetooth is generally a bad idea compared to WiFi, as the bluetooth protocol is abysmal for handling transfers of large amounts of data. I would recommend using WiFi for that. I have been considering just removing bluetooth as an option for library synchronization as it's quite problematic (and not entirely reliable).
