Parent:
source/nordic-sdk/components/libraries/bootloader_dfu/experimental/dfu_app_handler.c@381:c997e9717fb7 
Synchronized with git rev 928a5e63

Author: Rohit Grover

Release 0.4.1

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



This is a minor release.



Enhancements

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



* Hide duplicate symbol definitions in ble_types.h. These have already been

  brought into ble/blecommon.h.



* Replace DiscoveredCharacteristic::setupOnDataRead() with

  GattClient::onDataRead().



* Implement new API GattServer::areUpdatesEnabled() to determine notification

  status for a characteristic.



Bugfixes

~~~~~~~~



* fix for #20: GattServer::addService() incorrectly initialized value

  attribute-handles. These were getting confused with characteristicIndex.

  Event handlers also return attribute handles correctly now; they were also

  previously returning characteristic indices.
