I want to transfer the code from nrf51822 dk board to a beacon kit, after connecting the beacon kit to the dk board, then I change PCA10026 to PCA20006 on the C/C++ define, and change the softdevice to "s110_nrf51822_7.1.0_softdevice.hex", then download the code, but the beacon is not working , what is the problem and how to deal with it?
