    Erel, thank you, it works great! Made a little UDP server. In Station and Access Point mode. However, after a wifi.StartAccessPoint2(...) the AP mode cannot be switched off anymore. Only, via the Arduino IDE by setting a WiFi.mode(WIFI_STA) which terminates the mode WIFI_AP or WIFI_AP_STA. It looks as if the wifi configuration is saved in a reserved memory area. It is not removed after flashing a new program, without new mode/configuration settings. I noticed something similar with LUA-NodeMCU.

    Something else, it is probably not possible to set the channel in AP mode? I used it with LUA-NodeMCU firmware, where a configuration structure can be specified: cfg={}, cfg.ssid="...", cfg.psw="...", cfg.channel=8 (1-14, 6 default), wifi.ap.config(cfg)

    See this post: https://www.b4x.com/android/forum/threads/esp8266-wifi-and-socket.69164/#post-438940

    You can set these parameters with:
    Sub Process_Globals
    Public Serial1 As Serial
    Private channel As Int = 14 'ignore
       Private ssid As String = "ssid" 'ignore
       Private password As String = "12345678" 'ignore
    End Sub

    Private Sub AppStart
    End Sub

    #if C
    void setSoftAP(B4R::Object* o) {
       WiFi.softAP(b4r_main::_ssid->data, b4r_main::_password->data, b4r_main::_channel);
    #end if
    miker2069 and Bert Oudshoorn like this.

    Thank you, it works! Did set the channel to 4 (14 did not work).
    Had to change the "Private" Globals into "Public".

    Could switch off the AP mode in a similar way, via (C) WiFi.mode(WIFI_STA);
    There exists even a WiFi.softAPdisconnect(true); statement, which removes the AP config.
