Ahojte, myslíte že my mně někdo dokázal pomoct spojit následující dva programy v jeden?
Tento slouží k připojení k wifi síti a vytvoření web serveru:

Oba kódy by měli fungovat zkoušel jsem, ale nevím jak docílit souběžného běhu, aby se mně vytvořilo AP a zároveň na něm vysílat server. Hlavně si nevím s nastavením modulu a severu jako takového.
Děkuji moc za pomoc.
