Does 5340 with using nordic controller support periodic adveritising?

[Deang]

Hi,

I run the sample zephyr/samples/bluetooth/periodic_adv on 5340, if the controller selected software-base (CONFIG_BT_LL_SW_SPLIT), the sample work well; if BT controller selected softdevice (CONFIG_BT_LL_SOFTDEVICE), the sample can't work, it failed when set  periodic advertising parameters, the error returned was -5, The following figure is the corresponding log information.

Does 5340 with using nordic controller support periodic adveritising? If yes, and how to implement?

Hi Deang, 

The Nordic Softdevice controller does have support for periodic advertising. 

You can have a look at the answer from Torbjørn here.

The network core (hci_rpmsg) need to be configured to support extended advertising. Basically you need to add hci_rpmsg.conf into child_image with: 

CONFIG_BT_EXT_ADV=y
CONFIG_BT_CTLR_ADV_EXT=y
CONFIG_BT_EXT_ADV=y
CONFIG_BT_PER_ADV=y

Hi Hung,

Thanks.

I missed the options CONFIG_BT_EXT_ADV and CONFIG_BT_PER_ADV, the sample would work after enable the options. But I'm a little confused, why the sample needs to add these options with Nordic controller, however, no need to add with zephyr controller.

Hi Deang, 
I don't have much insight about the Zephyr controller. My assumption is that the feature is enabled by default with the Zephyr controller. In our Softdevice controller it's disabled by default to optimize the space.
