    Every BLE examples in the SDK 4.2 have the behaviour you expect. The device switch in system_off mode after the adertising timeout.

    Therefore, you cannot be disconnected until a voluntary disconnection from the connected device.

    Just before switch off, a GPIO pin is defined to be able to wake up the chip. By wake up. I mean do a reset : the main function will be executed.

    Have a look in the BLE examples for more information.
