Revision:
118:620d28e7a1ba
Child:
119:18684018b83e
Release 0.2.0

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



Highlights:

  Introducing standard services to simplify applications.

  Add support for over-the-air firmware updates.



Features

~~~~~~~~



- This release introduces 'templates' for common services such as heart-rate,

  battery-level, device-info, UART, device-firmware-update etc. These services

  take the shape of class declarations within header files aggregated under a

  new folder called 'services/'. These service-classes provide a high-level

  API hopefully easing the burden of developing BLE applications. The

  underlying APIs to work with characteristics and services are still

  available to allow greater control if needed. We expect to grow the

  supported services to include all SIG defined BLE profiles.



- WriteCallbackParams now includes the characteristic's value-attribute

  handle; this changes the signature of onDataWritten().



- BLEDevice::onDataWritten() now allows chaining of callbacks--this means that

  it is possible to chain together multiple onDataWritten callbacks

  (potentially from different modules of an application) to receive updates to

  characteristics. Many services, such as DFU and UART add their own

  onDataWritten callbacks behind the scenes to trap interesting events. It is

  also possible to chain callbacks to functions within objects.



- Added the following expectation for GattCharacteristic: If valuePtr ==

  NULL, initialLength == 0, and properties == READ for the value attribute of

  a characteristic, then that particular characteristic may be considered

  optional and dropped while instantiating the service with the underlying BLE

  stack.



- Introducing the typedef GattAttribute::Handle_t to capture Attribute handles.



Bugfixes

~~~~~~~~



None.



Compatibility

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



The signature of onDataWritten() has seen a change; so application programs

using this new version of the BLE API will need minor modifications. Please

refer to sample programs under BLE team page.
