I'm having no luck compiling the sketch using any version of the IDE. The error is:

ESP_WIFISCAN_OLED_ACQUIRE:207: error: cannot pass objects of non-trivially-copyable type 'class String' through '...'
sprintf(myStr,"%s",WiFi.SSID(i)); // copy in the SSID

If you have any idea then I'd love to know,
Mike

Try the following instead :

Code: Select allsprintf(myStr,"%s",WiFi.SSID(i).c_str());
