Set BlueTooth ID

This seems like it should be simple, but I cannot seem to set a custom static BlueTooth ID on an nRF52832 under PlatformIO / Zephyr - it just keeps generating a random ID. I am calling 

bt_id_create, which is returning 0 (success).
        bt_addr_le_t bt_addr;

        bt_addr.a.val[0] = 0x26;
        bt_addr.a.val[1] = 0xF8;
        bt_addr.a.val[2] = 0x64;
        bt_addr.a.val[3] = 0xC4;
        bt_addr.a.val[4] = 0x6A;
        bt_addr.a.val[5] = 0xCB;
        bt_addr.type = BT_ADDR_LE_RANDOM;

        uint8_t irk[16] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 };

        int err = bt_id_create(&bt_addr, irk);
        
        int err = bt_enable(bt_ready);
