SW will queue all the requests and move things into the hardware as slots are available, but at best there are ~100 available hardware slots. You will need to scan to know which devices are around before attempting to connect. - Craig

Hi All,

I'm wondering if there's a limit to how many devices Core Bluetooth can be registered to connect to. Note that these aren't simultaneous connections; there will only be 1-2 max connected at a time. We plan on having a whitelist of 20k BLE devices we manufacturer that our app can connect to and need to have an iOS device able to connect to any one of them. Is there any limitations of problems with doing this? This would be similar to Tile's "lost mode" where anyone's phone can find your Tile.
