Hi Nordic team,
I have 2 nRF52840 DK boards.
I followed the steps mentioned in the below link, I am able to Transfer the DFU archive over serial with nrfutil(LED keeps blinking on the DFU performed board).http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v1.0.1%2Fmd_doc_getting_started_dfu_quick_start.html
But when i checked to verify that the boot loader is working correctly or not, I am getting below error, I am not sure, What mistake i have done ? Please help me on this as well.

Device family: NRF51
Reading UICR.. ERROR: The --family option given with the command (or the default from

Error calling nrfjprog with arguments -s 683713355 --memrd 0x10001014 --n 4 --w 32 --family NRF51.
Please provide your inline comments to below queries,
1. After successful transfer the DFU archive over serial with nrfutil, Now how to transfer the firmware packets from one DK board(Contains firmware transferred over serial with nrfutil) to another DK board ?
Is it automatically perform DFU over BLE from one board to another board ? Please let me know the exact test steps to transfer DFU from one board to another board over mesh through BLE.
2. What is test bench mark to know DFU over BLE is done between one nRF52840 DK board with firmware package and another board with out firmware package ?
3. How to know two devices(One nRF52840 DK board with firmware package and another board with out firmware package) are connected in mesh, while performing DFU ?
