My colleague Karl shared some more details about this in this case.

As he writes you need at least NCS v1.6.0 or later in order to support multiple advertising sets.

No, this is not necessary, as long as you use v1.6.0 or later.

As I understand, Hung's answer in the other case was possibility about BLE scanner.

Do you mean it's fine to start two advertisement with 1M PHY and coded PHY in Zephyr?

If then, do you have any reference or example about this? (or document)

And should I change Zephyr's BLE stack source code?

BTW, FYI,

My project based on NCS ver.1.4.1

And 'CONFIG_BT_LL_SW_SPLIT=y' is applied because for AoA feature. (is that ok for PHY update?)

Thanks for your support.

P.S.

I found 'BT_LE_ADV_OPT_CODED' param option.

But it doesn't works with adv. start fail error. (bt_le_adv_start() function, returned error code is -22)

Susheel's answer is in a 3 year old case, and is referring to the SoftDevice implementation, not Zephyr.

In Zephyr this should be possible, as mentioned by Hung in the other case.
