NCS v1.5.0 "Bluetooth: EnOcean" sample: Bluetooth init failed

Question

Hi, 
 starting the NCS v1.5.0 "Bluetooth: EnOcean" sample on nRF52840 DK, the following error occurs: 
 Bluetooth init failed (err -35) 
 *** Booting Zephyr OS build v2.4.99-ncs1 ***
I: 8 Sectors of 4096 bytes
I: alloc wra: 0, ff0
I: data wra: 0, 0
I: SoftDevice Controller build revision:
I: e5 c7 9c d9 91 00 1d 66 |.......f
I: ea fb 6e 7b 98 2f 42 0d |..n{./B.
I: f1 60 93 c8 |.`..
E: HCI driver open failed (-35)
Bluetooth init failed (err -35) 
 Any suggestions? Thank you.

It works after configuration change from: ...
# Common SoftDevice Controller module configuration
#
CONFIG_SOFTDEVICE_CONTROLLER_PERIPHERAL=y
# CONFIG_SOFTDEVICE_CONTROLLER_CENTRAL is not set
# CONFIG_SOFTDEVICE_CONTROLLER_MULTIROLE is not set
... 
 To: # CONFIG_SOFTDEVICE_CONTROLLER_PERIPHERAL is not set
# CONFIG_SOFTDEVICE_CONTROLLER_CENTRAL is not set
CONFIG_SOFTDEVICE_CONTROLLER_MULTIROLE=y 
 And the result is: *** Booting Zephyr OS build v2.4.99-ncs1 ***
I: 8 Sectors of 4096 bytes
I: alloc wra: 0, fd0
I: data wra: 0, 2c
