Two parameters are expected by the template:
- TPalSecurityManager a template class of the security manager of the form TPalSecurityManager<EventHandler>. The GenericSecurityManager is the event handler.
- SigningMonitor a template in the form SigningMonitor<Handler>.
GenericGattClient is parametized by two types:
- The template of the PalGattClient
- The SigningMonitorEventHandler
Note that the PalGattClient template must be of the form PalGattClient<EventHandler>. The event handler being the GenericGattClient.
Expected types are similar to the type expected by the constructor:
- PalGap
- PalSecurityManager
- ConnectionEventMonitorEventHandler
Note that for the PalGap we expect a **template** of the form PalGap<EventHandler>
The interface now lives in ::ble::interface::SecurityManager. The implementation type is expectected to exported as ble ::ble::impl::SecurityManager by the implementation.
The GenericSecurityManager tracks the most recent OOB data generated
by the PAL and the PAL function to generate OOB data is expected to
be asynchronous such that the OOB data is returned via a callback.
There was a race condition on the security manager's oob data variable
because it was cleared (set to all zeros) after calling PAL generate.
The expectation was that the clear operation would occur before the
callback executed, but this is proving to not be the case. Instead,
the callback is being executed as if it were syncronous with PAL
generate, then PAL generate returns and the oob data is cleared,
thereby losing the generated oob data that was set in the callback.
To fix the issue, clear the oob data variables before calling into
the PAL.

Unlike the public address, the RANDOM address is guaranteed to exist.
If privacy is enabled, it means the controller will generates random resolvable addresses or non resolvable addresses depending on the config.
If privacy is not enabled then the device will use the device's random static address that doesn't change between radio processes.
