hciStatus_t HCI_EXT_DeclareNvUsageCmd ( uint8 mode)
This command informs the controller whether the host uses NV memory during
Bluetooth Low Energy operations. The default system value for this feature is NV
In Use. When the NV is unused during Bluetooth Low Energy operations, the
controller can bypass internal checks that reduce overhead processing. This
capability reduces average power consumption.

NOTE: This command is allowed only when the Bluetooth Low Energy controller
is idle.
If you use NV when declaring it is not in use, a hung Bluetooth Low
Energy connection may occur.
NOTE: Only the application should use this command. Incoming encrypted
Bluetooth Low Energy data is automatically decrypted by the stack and
operates free of this API.
