 +What options do you have for modifying the SDK script to suit your needs?
  
 {{:app-notes:wlan_skript_einstellung.png?950|}} {{:app-notes:wlan_skript_einstellung.png?950|}}
 +
 +In the upper section, you can enter the SSID''(WLAN name of the access point)'' under ''point 1''. Four placeholders have been entered in the script. However, these can be expanded as required. The password for the access point is entered under ''point 2''. It is ''very important'' to assign the SSID to the correct password. Both pieces of information ''must be'' entered in the same order in the script.
 +
 +
 +Under ''point 3'', you can determine where the Wi-Fi should be entered. In this setting, ''“wlan_client_entry = 10”'', the Wi-Fi is added as the last entry in the client list. The entered Wi-Fi networks ''“test1 to test9”'' are also given priority by the router. If you enter the Wi-Fi network in the first position, it not only receives priority status 10, but you also use all Wi-Fi networks from your list before those stored permanently in the router. In this example, it is exactly the opposite. First the permanently stored networks and then the Wi-Fi list.
 +
 +Under ''point 4'', you can choose whether you want to use WLAN module 1 or WLAN module 2 for the entire system.
