--------------------------------------------------------------

Hi guys, just wanted to report that we've tested the proposed fix for this issue (removing the call to ble_ll_ctrl_proc_start() in ble_ll_conn_created()) and our iOS dev is still seeing intermitting cases (that are hard to reproduce) where the iOS 11 is "totally stuck" and can never connect to the device again, unless BT is toggled on the phone. He's tested with iPhone 7 and iPhone X. Are there any further updates / proposed fixes to this that we can try and test?

> Master: iPhone running iOS 11
> Slave: NimBLE device
> The iPhone successfully establishes a connection to the NimBLE device, but the CoreBluetooth {{didConnect()}} callback does not get called.  A packet trace (see attached) shows that the iPhone never initiates service discovery.
> The problem seems to occur when the NimBLE controller initiates the Feature Exchange Procedure immediately after connection establishment. The {{LL_SLAVE_FEATURE_REQ}} PDU appears to cause a problem for the iOS device.  When I comment out the call to {{ble_ll_ctrl_proc_start()}} at the bottom of {{ble_ll_conn_created()}}, the iOS device is able to connect and perform service discovery, resulting in the CoreBluetooth callback being executed.
> In the attached pcap file, the CONNECT_REQ is at packet #6211.
