@wuvo.leo: You can simply remove the part that we change the address in the bootloader at dfu_transport_update_start() , where we call sd_ble_gap_address_set().

You can have a look here at question I, for the explanation why we do that.

dfu_transport_ble.c

@wuvo: I don't see the same result as your. On Master Control Panel app I can see the DFUTARG device name. In your case you had the issue because you tried to put all the device name, service uuid, and manufacturing data in to the scan response, which of course doesn't have enough space (31 bytes). If you remove the service uuid in the scan response, it should be fine.

I attached in my answer the modified dfu_transport_ble.c file, please replace your file and let me know the result.
