M5CAMERA - ESP32-CAM в заводской упаковке

Приветствую, друзья!
Долго не писал, потому что обстоятельства отвлекли от всевозможных "сделай сам".
Сейчас попался заказ на программирование шлагбаума с разпознаванием номера автомобиля.

Для этого предполагается что камера будет слать данные на сервер, где они будут в режиме реального времени обрабатываться распознавалкой (я остановился на iANPR) и в случае срабатывания - подъем и через некоторое время опускание.

Сам шлагбаум уже есть, мне надо только дать сигнал на открывание, дальше он уже сам со своими настройками.
Для передачи информации на сервер я выбрал FTP. Не знаю, почему меня заусило именно этот протокол, а не лить в HTTP или по MQTT.
В качестве интернета - WiFi роутер, недавно на алишке нашел недорогой, с симкой.

Трудности в том, что стандартный пример из Arduino не видит камеру а FTP может отваливаться и при этом камера "зависает". Предложенные примеры в интернете пестрят ошибками, например нет очистки буфера камеры, что приводит к смерти.

В итоге, после красноглазой ночи получился код, который очень стабильно шлет набор картинок на сервер и перезагружает девайс если что-то подзависло. Работает ТОЛЬКО на M5CAMERA, если хотите ESP32-CAM то надо заменить блок cameraconfigt config на тот, что есть в стандартном примере

Telegram Gives Up On Crypto Blockchain Project

Durov said on his Telegram channel today that the two and a half year blockchain and crypto project has been put to sleep. Ironically, after leaving Russia because the government wanted his encryption keys to his social media firm, Durov’s cryptocurrency idea lost steam because of a U.S. court. “The technology we created allowed for an open, free, decentralized exchange of value and ideas. TON had the potential to revolutionize how people store and transfer funds and information,” he wrote on his channel. “Unfortunately, a U.S. court stopped TON from happening.”
