Naming problem

[Ding]

The interface "sd_ble_gap_adv_start" uses "adv" to indicate broadcast, but the interface "ble_advertising_start" uses "advertising" to indicate broadcast. Why not use the same name?

[Turbo J]

Two totally different APIs.

The sd_ble_xxx macros call directly into the softdevice and follow a common naming scheme.

The ble_advertising_xxx functions are executed in the application space and will eventually call the sd_ble_xxx softdevice, but users are not supposed to call the softdevice functions direcly as that can cause errors.

TL;DR Different naming scheme is intentional.

Is it mainly to prevent customer misuse?
