Starts specific AP scan, asynchronously.

This function starts a Wi-Fi scan targeting a specific access point (AP) with the given ESSID (Extended Service Set Identifier).

Starts multi SSID and multi channel specific scan, asynchronously.

This function starts a Wi-Fi scan targeting multiple specific access points (APs) across multiple channels simultaneously. Unlike a regular scan, which searches for all available APs in the vicinity, a specific scan focuses on a predefined set of APs, which can improve scan efficiency and reduce scan time. The multi-SSID and multi-channel specific scan extends this concept further by allowing the scan to target multiple sets of APs across different channels at once.
