Thank you for the valuable advice. In the current implementation we are testing, all three are set to 'y'.

For similar settings, the situation is as follows:

CONFIG_BT_EXT_ADV_LEGACY_SUPPORT is not set
CONFIG_BT_CTLR_ADV_EXT_SUPPORT=y
CONFIG_BT_CTLR_PHY_CODED_SUPPORT=y

Regards,

Junpei

Hi,

Could you try to add the following configs into child_image/hci_ipc.conf as this sample?

CONFIG_BT_EXT_ADV=y
CONFIG_BT_CTLR_ADV_EXT=y
CONFIG_BT_CTLR_PHY_CODED=y

Regards,
Amanda H.

Hi,

bt_le_adv_param handles parameters for legacy/extended advertising, instead of broadcasting on isochronous channels. bt_iso_chan_io_qos is the right struct to go and for the sample usage, check out iso_combined_bis_and_cis or iso_time_sync on nRF Connect SDK. Hope that helps!

Cheers,

Yuxuan
