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

[dwm]

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: f1 60 93 c8             |.`..
E: HCI driver open failed (-35)
Bluetooth init failed (err -35)

Any suggestions?
Thank you.

Have you looked-up what the -35 error code means?

[dwm]

Yes, I've looked-up it:

main() : bt_enable() : bt_dev.drv->open() : hci_driver_open() : sdc_support_scan() : 

   returns -NRF_EOPNOTSUPP (-45) "Scanning state is not supported" :
           -ENOTSUP        (-35) "Unsupported value"

[awneil]

So I guess you need to find which value it's complaining about, and use one that is supported?

[dwm]

Ok, but the "Bluetooth: EnOcean" sample is not my project, so I would like to hear the author's opinion on this error/bug first.

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:
