Add an onShutdown() function to Gap, GattClient, GattServer and
SecurityManager. The callbacks are added to a private callback chain in each of
the instances. The callbacks will be executed inside each object's reset()
function BEFORE the state of the instance is cleared. The developers of the
platform-specific implementation must call the parent class' reset() function
for the callbacks to be executed.
Finally, an onShutdown() function that returns the shutdown callchain is added
to allow detaching callbacks.
Modify the shutdown API to remove the static shutdown function in Gap,
SecurityManager, GattClient and GattServer. Futhermore, remove the static
references to Gap, SecurityManager, GattClient and GattServer objects inside
their own classes. The cleanup method is renamed to `reset()` and made public.
Finally, additional functionality is added to the reset implementation in
The BLE API exposes a shutdown() function in BLE.h. This function is meant to
be overwridden by platform-specific sub-classes to clear all GAP and GATT
state. However, from the platform-specific implementation it is dificult to
achieve this because the Gap, GattClient, GattServer and SecurityManager
components of the API do not expose any functionality to shutdown.
This commit introduces the following changes:
* Add a static member pointer to Gap, GattClient, GattServer and
SecurityManager that is used to keep track of the initialized objects.
* Add a function member cleanup() to Gap, GattClient, GattServer and
SecurityManager to allow easy reset of the instance's state. This function
is meant to be overriden and called from the derived classes to fully clear the
state of the BLE API and the platform-specific implementation.
* Add a static member function shutdown() to Gap, GattClient, GattServer and
SecurityManager. This function shall be called from the shutdown()
overriding BLE::shutdown() for Gap, GattClient, GattServer and SecurityManager
that will in-turn clear the state of each of the components.
**NOTE:** Platform-specific implementations of this API must be modified to
this changes into account.
Introduce abality to explicitly perform a notify/indicate opertion on a characteristic.
This brings benefits of a reduce RAM footprint for storing GattCharacterisitics.
n.b. temporary measure until ARM mbed integrate more generic optimisations.
* Added byte ordering parameter to UUID construction for long UUIDs. The
default remains as Big-Endian.
* Add a doxyfile that warns for undocumented elements.
* Minor fixes for some documentation.
