There are new pseudomodules for this driver: - atwinc15x0_static_connect: Should behave as before, by trying to connect to an AP by specified WIFI_SSIS and WIFI_PASS - atwinc15x0_dynamic_connect: takes connection request via NETOPT_CONNECT and provides the connection result via callback - atwinc15x0_dynamic_scan: takes network scan requests via NETOPT_SCAN and provides the scan result as a sorted list via callback
