# Overview
  
  This package provides necessary Makefiles and glue code to use the Nordic S132
  SoftDevice as Bluetooth BLE transport for RIOT's 6lowpan stack.
  
  # Usage
  
  "gnrc_netdev_default" has a dependency to "nordic_softdevice_ble", so all
  examples automatically download the SDK and compile / link / flash all needed
  code.
  
  If you want to manually set up included modules, add "USEPKG +=
  nordic_softdevice_ble" to your application's Makefile.
  
  See README-BLE-6LoWPAN.md for instructions on how to set up 6lowpan over BLE on
  Linux.
  
  # Known issues
  
  - floating point ABI mismatch
  
  The Nordic binaries are compiled using hard float ABI, which RIOT currently
  doesn't support (RIOT's context switching code doesn't preserve the floating
  point registers).  If the softdevice is compiled in, RIOT will be compiled with
  hard float ABI in order for the linking to succeed.  This works for some
  application, but will lead to serious and hard-to-find bugs for code using
  floating point instructions.
  
  Hopefully, either the RIOT community adds hard-float support, or Nordic
  releases a soft-float version of the used binaries.
