Most likely, if the advertisements are connectable.

[quote user="cosmotic_instant"] it does not appear to be built into my project. [/quote]

conn.c probably has GAP function calls. So the BT GAP functionality is present.

Does advertising stop when a peripheral is connected?

If i wanted to change advertising interval via a characteristic, such that when it disconnected, it'd call its bt_le_adv_resume function, and it'd have different setting from when bt_le_adv_start was called, how would i do this?

Though i see the bt_le_adv_stop function in the gap.c file in the zephyr API documentation, it does not appear to be built into my project. It appears to only have conn.c, adv.c, hci_core.c, but no GAP...? the adv.h gives a few public functions like bt_le_adv_start, but it doesn't appear to reflect zephyrs api documentation... im using NCS 1.7.1.

You need to call bt_le_adv_stop, update the advertising parameters, then call bt_le_adv_start.
