RE: Fatal dfu log:Setting vector table to bootloader: 0x00078000

Hi,

The Buttonless characteristic use a 128-bit vendor specific UUID, which is why you had to set NRF_SDH_BLE_VS_UUID_COUNT to '1' and allocate more memory to the Softdevice. It is also required to change the vector table as you noted. You can read more about the SVCI interface here: https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/lib_svc.html?cp=5_1_3_50 .

Tip: you can add "DEBUG" to the list of pre-processor definitions as shown below to get a more detailed crash log.
