Can I run nRF51 Bluefruit sketches on the nRF52?
No. The two board families are fundamentally different, and have entirely separate APIs and programming models. If
you are migrating from the nRF51 to the nRF52, you will need to redesign your sketches to use the newer API,
enabling you to build code that runs natively on the nRF52832 MCU.
