The linked reply is still accurate. Simply stop, re-configure, and start advertisement from for instance an app_timer can work (e.g. every 500ms).

Hi,

1) Is this answer is still relevant?

2) Is it possible to declare 2 of "advertising_init" with different defining and tags? and operate them simultaneously ?!

3) What is the best way to advertise in 1m phy and in coded phy to allow phones (wich use ble 4.2 only) or my custom central long range devices to "see" the pheripheral and connect to it (not simultaneously !) ?

Yes, you will have to start and stop advertisement.

I'm replying myself again - I saw this thread, https://devzone.nordicsemi.com/f/nordic-q-a/35596/advertising-on-two-different-phy-simultaneously , is the answer there still relevant?

I have played with the following configuration:

The following makes phone supporting BT4.2 see the adv but DK running long range central example cannot see/connect to to the peripheral DK.

init.config.ble_adv_primary_phy = BLE_GAP_PHY_1MBPS;
init.config.ble_adv_secondary_phy = BLE_GAP_PHY_CODED;/**< Enable or disable extended advertising. */
init.config.ble_adv_extended_enabled = false;/**< Enable or disable extended advertising. */

BT4.2 phone cannot see the adv using the following config:

init.config.ble_adv_primary_phy = BLE_GAP_PHY_CODED;
init.config.ble_adv_secondary_phy = BLE_GAP_PHY_1MBPS;/**< Enable or disable extended advertising. */
init.config.ble_adv_extended_enabled = true;/**< Enable or disable extended advertising. */

Can you please give us some code snippets which can support both long range and 4.2 only phy?

Thanks
