Extended advertising fails with zephyr Host - Controller configuration

Forget the last reply. The reason it didn't work for the nrf52833 was because there were no nrf52833.conf file in the folder zephyr/samples/bluetooth/periodic_adv/boards.

I was trying to set everything up to reproduce your problem, and thought I would start with the ibeacon sample, to make sure I got it right. However, I encountered some problems (I've don't have too much experience with BLE host controller on separate chips). Would you be able to upload the ibeacon sample as well as the periodic_adv sample you used on the nRF9160 DK, and the lpuart sample (if modified) you used on the nRF52833 DK?

Update 29/04/2021: Added strikethrough over false statement

Have you made any progress on this lately?

It seems like this is related to the 52833 specifically.

In zephyr\samples\bluetooth\periodic_adv\prj.conf (NCS v1.5.0) I added CONFIG_BT_LL_SW_SPLIT=y, then I built and flashed the example for respectively the nrf52833dk_nrf52833 and the nrf52840dk_nrf52840 (host and controller on the same chip).

For the nrf52840dk_nrf52840 I got the following output:

For the nrf52833dk_nrf52833 I got this output:

Have you tested using an nrf52840dk as the controller? Does it work then.

I will due some more investigations and get back to you with clearer answers.

Sorry for the delay on this. I will look into it on Friday/Monday.

I think to run periodic advertising sample, using Zephyr controller is necessary so all aforementioned problems occurred while CONFIG_BT_LL_SW_SPLIT=y

I guess this is related to https://devzone.nordicsemi.com/f/nordic-q-a/72923/nrf-connect-mobile-app-doesn-t-show-advertising-nrfxlib. Are you able to use extended advertising with the Zephyr BLE controller?

Some developers are currently looking into this, and I'll keep you updated.

Hi Simon,

I am using 1.5.0 SDK and can confirm these PRs are already applied.

Could you try to apply the PRs pointed to in this ticket to your project, and see if the error goes away?
