I had the same problem with my X-NUCLEO-BNRG2A1 based on BLUENRG-2, connected to my ST-link V2 clone. My mistake was that I forgot to short the J15 jumper, whose name is "boot pin jumper" and whose description is "Boot pin connect to VDD , for wake up device when in sleep". Hope this will help someone.
