Currently I am working on Zephyr Bluetooth APIs to build normal
Services-Characteristics based BLE device.

I've observed following things:
1) sometimes when app (for eg. nRF Connect) closes even after that device
doesn't get disconnected

2) sometimes even smartphone Bluetooth switched off then also device doesn't
go from connect state to disconnect state.

Success ratio is approx. 60-70%

Since device doesn't go in disconnected mode, it stop advertising & I have
to restart it for reconnection.

Is it because of App or smartphone OS not actually disconnecting at
background level ?
ATT/GATT is tied with the ACL connection which is maintained by the
controller, so there is very little the host stack can do about it but
perhaps if you are running with combined controller + host then we
need to check why the controller side cannot detect the ACL has been
