В общем, прошил вот таким скетчем через Arduino ESP-01
Точка доступа появляется, даже пару раз удалось зайти на 192.168.4.1 и "You are connected" прочитать, но в остальном ноут постоянно переподключается к точке, постоянное соединение не устанавливается: подключение, инициализация, подключено - бах, по новой.
Вообще же дальше буду собирать вот такую схему:
и там telnet-сервер нужен
Но хотя бы вот стабильно рабочую точку создать.
Помогите, пожалуйста. Может, что в подключении не так (после прошивки подключаю как на втором рисунке, только RX-RX TX-TX оставляю с Adruinкой.
