Release 0.4.0

=============



This is a major release which introduces the GATT Client functionality. It

also aligns BLE_API with builds using our new package manager: yotta

(https://github.com/armmbed/yotta).



Many APIs have seen some redesign. We encourage our users to pay attention to

the changes and migrate appropriately over time. We've also taken care to

ensure that existing code continues to work the same way. There's more

documentation in the form of comment headers for APIs to explain proper usage;

in many cases comment headers suggest alternative use of APIs.



Enhancements

~~~~~~~~~~~~



* Introduce GattClient. This includes functionality for service-discovery,

  connections, and attribute-reads and writes. You'll find a demo program for

  LEDBlinker on the mbed.org Bluetooth team page to use the new APIs. Some of

  the GATT client functionality hasn't been implemented yet, but the APIs have

  been added.



* Most APIs in the abstract base classes like Gap and GattServer return

  BLE_ERROR_NOT_IMPLEMENTED. Previously many APIs were pure-virtual, which did

  not permit partial ports to compile.



* We've added a new abstract base class for SecurityManager. All security

  related APIs have been moved into that.



* BLEDevice has been renamed as BLE. A deprecated alias for BLEDevice is

  available to support existing code.



* There has been a major cleanup of APIs under BLE. APIs have now been

  categorized as belonging to Gap, GattServer, GattClient, or SecurityManager.

  There are accessors to get references for Gap, GattServer, GattClient, and

  SecurityManager. A former call to ble.setAddress(...) is now expected to be

  achieved with ble.gap().setAddress(...).



* We've cleaned up our APIs, and this has resulted in dropping some APIs like

  BLE::reset().



* We've also dropped GattServer::initializeGattDatabase(). THis was added at

  some point to support controllers where a commit point was needed to

  indicate when the application had finished constructing the GATT database.

  This API would get called internally before Gap::startAdvertising(). We now

  expect the underlying port to do the equivalent of initializeGattDatabase()

  implicitly upon Gap::startAdvertising().



* The callback for BLE.onTimeout() now receives a TimeoutSource_t to indicate

  the cause of the timeout. This is perhaps the only breaking API change. We

  expect it to have very little disruptive effect.



* We've added a version of Gap::disconnect() which takes a connection handle.

  The previous API (which did not take a connection handle) has been

  deprecated; it will still work for situations where there's only a single

  active connection. We hold on to that API to allow existing code to migrate

  to the new API.



Bugfixes
