Я использую NODEMCU (версия 0.9, модель ESP8266MOD) в WIFI Soft Access Point для управления моими огнями с помощью реле. когда он подключен, требуется время, чтобы открыть заданный IP-адрес для управления источниками света, и иногда он не подключается, а если он подключен, веб-страница IP не открывается, откуда мы можем управлять источниками света .. помогите
