Andres Amaya Garcia 0bcc2e96c9 Modify shutdown due to BLE API change
The module is updated to comply with the changes to BLE API regarding correct
shutdown functionality. The following changes are introduced to ble-nrf51822:

* Calls to the old static function shutdown in Gap, GattClient, GattServer and
SecurityManager are removed.
* The cleanup function in Gap, GattClient, GattServer and SecurityManager is
renamed to `reset()` and made public.
* The static references inside nRF5xGap, nRF5xGattClient, nRF5xGattServer and
nRF5xSecurityManager to objects of their own class are moved to nRF5xn.
* The static getInstance accessors in nRF5xGap, nRF5xGattClient,
nRF5xGattServer and nRF5xSecurityManager are removed and their functionality is
moved to the implemented virtual accessors in nRF5xn i.e. getGap(),
getGattClient, etc.
* A static function Instance is added to nRF5xn class to make the transport
object accessible across the module.

Andres Amaya Garcia 7bf81e7edb Improve shutdown to clear BLE API and not just SD
Improve the shutdown functionality, such that a call to ble.shutdown() from
the user application clears the API and nRF5x state and NOT only the
SoftDevice. To achieve this the following changes are introduced:

* Add a protected member cleanup() to nRF5xGap, nRF5xGattClient,
nRF5xGattServer, nRF5xSecurityManager and nRF5xServiceDiscovery.
* Modify the shutdown() implementation in nRF5xn such that it also calls the
static member shutdown() exposed by the BLE API in Gap.h, SecurityManager.h,
GattClient.h and GattServer.h.
* Modify nRF5xGattClient, nRF5xGattServer and nRF5xSecurityManager
classes so that they dynamically create their respective objects only if
needed. Previously the GattClient, GattServer and SecurityManager objects were
declared as static, which means that they were always present even though they
were not always needed. This increases memory consumption unnecessarily.
Furthermore, pointers to the object instances are stored in static members of
the classes as specified by the BLE API base classes. This ensures that
calls to shutdown do not require calls to getInstance() functions that would
otherwise result in undesired memory allocations.
* nRF5xGap object is always needed, so this remains allocated statically. But
the reference in Gap is pointed to this object.

The shutdown procedure is as follows:

1. The user calls ble.shutdown() which executes the code in nRF5xn::shutdown()
1. The SoftDevice is shutdown
1. The static members of Gap.h, SecurityManager.h, GattClient.h and
GattServer.h are called to clean up their own state.

If at any point an error occur during the last step, BLE_ERROR_INVALID_STATE is

Jean-Philippe Brucker eab6631cb6 Update S110 detection macros again
The mbed SDK actually prefixes all labels from with "TARGET_".
Update our detection macros accordingly.

Jean-Philippe Brucker dc1d7893c4 Update S110 detection macros
Those macros are defined by mbed SDK in They changed from
MCU_NORDIC_xxx_S110 to MCU_NRF51_xxx_S110. Update the #ifdefs accordingly.

Rohit Grover 2c01109786 Merge pull request #38 from jpbrucker/s110_compat
Disable GattClient features when using S110 SoftDevice

Jean-Philippe Brucker 3eabc779a0 Disable GattClient features when using S110 SoftDevice
S110 compatibility is already present, but this patch adds proper handling
of observer/central related features:
* Gap::startScan will return BLE_ERRROR_NOT_IMPLEMENTED (instead of
* nRF5xGattClient uses the default GattClient implementation when S110 is
  in use. All if its methods return NOT_IMPLEMENTED.

Example: for an application that acts as both a central and a peripheral,
using S110 will make the call return
BLE_ERROR_NOT_IMPLEMENTED, and advertisement features will continue
running normally.
In addition, with GCC, this patch will free 344 bytes of RAM and 2504
bytes of flash.

Rohit Grover e699db6a54 nRFGattClient: move the allocation of the singleton to within the getInstance() method.
This saves memory when getInstance() isn't used.

Rohit Grover 0eb58d86f5 rename nRF51... to nRF5x...
This prepares us to support nRF52.
