* Before compiling this example for NRF52, complete the following steps:
* - Download the S212 SoftDevice from thisisant.com.
* - Extract the downloaded zip file and copy the S212 SoftDevice headers to \/components/softdevice/s212/headers.
* If you are using Keil packs, copy the files into a @c headers folder in your example folder.
* - Make sure that @ref ANT_LICENSE_KEY in @c nrf_sdm.h is uncommented.
