Подключаюсь к нему монитором (пробовал и putty, и arduino serial monitor с Both NL & CR, и Terminal v1.9b с разными настройками окончания строки), AT-команды не отправляются. Т.е. они отправлются (смотрел логическим анализатором, подключившись к TX1/RX1), но esp32 на них никак не реагирует.

Вывод монитора:
