Hi,

You should flash the hex-file that the compiler you use output, after building the project where you added the required changes for the application to work with your customized board.

Most compilers store the hex-files in "_build", "build", "Output", or similarly named directory in the project folder.

Best regards,

Did you also flash the softdevice from nRF5_SDK_15.2.0_9412b96\components\softdevice\s132\hex\s132_nrf52_6.1.0_softdevice.hex?

Do you have the 32.768 kHz LF crystal on your custom board? If not, you must make sure the project is configured to use the internal RC oscillator.
