The DCDC was not used in regulatory testing for earlier softdevices, so it may affect regulatory compliance.</p> <p>The functional penalty of operating the DCDC with the softdevice on a second revision nRF51 is unreliable radio activity, as DCDC may interfere with it. It may result in occasional link losses, etc. If consuming relatively high current just before a BLE radio event will increase the chances of successful radio transmissions when using the DCDC.
