        On my iPhone 6S Plus (A1634) on iOS 13.3 my peripheral scan is getting interrupted and the CBCentralManager resets every few minutes with the following message in the Xcode console:

         

        [CoreBluetooth] XPC connection interrupted, resetting

         

        I dug around in the device console logs and found the following bluetoothd error messages that correspond with the times of the resets:

         

        error 08:20:41.483385-0500 bluetoothd HCI expected event 14 with opcode OI_DHCI_VENDOR_OPCODE (0x0000FD4D) timedout, reason is  STATUS 621

        error 08:20:41.483670-0500 bluetoothd status 621, hlCb 0x00FE2B6C

         

        The same code running on an iPhone X with 13.3 and an iPad with iOS 12 doesn't show the issue.

         

        I'm wondering how broad this issue is likely to be as it is definitely hampering the performance of our app on this device. But I'm not sure if it's specific to my phone, all iPhone 6Ss on iOS 13, all older iPhones on iOS 13, etc.

         

        Any thoughts?

         

        Thanks!
