Can I set ADV_EXT_IND without AUX packet？

[qianjunwang]

Hi，

In Core Specification v5.4, there is support for Non-Connectable and Non-Scannable Extended Advertising (ADV_EXT_IND) without AUX packets. However, when using Nordic's NCS v2.5.0, the advertising configuration only provides three options about it:

• BT_LE_ADV_OPT_EXT_ADV
• BT_LE_ADV_OPT_CONNECTABLE
• BT_LE_ADV_OPT_SCANNABLE

This appears to limit the ability to configure extended advertising (ADV_EXT_IND) without AUX packets. Specifically:

1. Is ADV_EXT_IND equivalent to "extended advertising" in this context?
2. How can I achieve non-connectable, non-scannable extended advertising (without AUX) in NCS v2.5.0?
3. Are there additional configuration flags or workarounds to enable this mode?
