It contains references and code for Bluetooth Low Energy devices in the nRF52 Series, though development on these devices is not currently supported with the nRF Connect SDK.&quot;</em></p> <p><strong>The nRF52-series has its own SDK, known as the nRF5-SDK, which is <a href="https://infocenter.nordicsemi.com/topic/struct_sdk/struct/sdk_nrf5_latest.html?cp=6_1">found here</a>.
