Dependents:   idd_hw5_bleFanProto

Fork of nRF51822 by Nordic Semiconductor

nRF51GattServer.cpp@66:b3680699d9a4, 2014-09-22 (annotated)

Committer:
Rohit Grover
Date:
Mon Sep 22 11:19:51 2014 +0100
Revision:
66:b3680699d9a4
Parent:
57:2aa01a5008ac 
Release 0.2.0

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



Highlights:

  Add support for over-the-air firmware updates.



Features

~~~~~~~~



- Add files to support DFU bootloader.



- charHandle is now a part of GattCharacteristicWriteCBParams.



- nRF51GattServer::addService(): Skip any incompletely defined, read-only

  characteristics. For instance, the DeviceInformationService may have many

  optional, read-only characteristics which may be safely dropped if the

  application hasn't defined them.



Bugfixes

~~~~~~~~



None.



Compatibility

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



Works with 0.2.0 of BLE_API.
