What ' s the problem

When I make the nRF51 ' s DFU project appear "No UECC.h" error:

And then find That:the UECC Library was an external library that's not a part of the SDK and it must being installed by the User.

Installing MICRO-ECC

MICRO-ECC is a open source library that's required to use the Cryptography library. When using MICRO-ECC, you must ensure compliance with the license of the library as stated in the LICENSE.txt file Included in MICRO-ECC.

The cryptography Library expects to find the compiled MICRO-ECC library in InstallFolder\external\micro-ecc\micro-ecc .

To install MICRO-ECC, complete the following steps:

2. Install version 4.9-2015-q3-update of the GCC compiler toolchain for ARM. You can use ARM's Launchpad to find the toolchain for your operating system.
4. Make sure it is installed (see, for example, MinGW, GNU make, or Xcode).
6. Clone the MICRO-ECC GitHub repository into InstallFolder\external\micro-ecc\micro-ecc .
8. Enter the subdirectory for the SoC and the Toolchain, which is the using to build your application:
   • InstallFolder\external\micro-ecc\nrf51_keil\armgcc
   • InstallFolder\external\micro-ecc\nrf52_keil\armgcc
   • InstallFolder\external\micro-ecc\nrf51_iar\armgcc
   • InstallFolder\external\micro-ecc\nrf52_iar\armgcc
   • InstallFolder\external\micro-ecc\nrf51_armgcc\armgcc
   • InstallFolder\external\micro-ecc\nrf52_armgcc\armgcc
10. Run make to compile the MICRO-ECC library.
