pygatt подключается, но не может подписаться, а bleak подключается и может подписаться: почему bleak не воспроизводится с помощью pygatt?

Я пытаюсь подписаться на одну характеристику на устройстве BLE. С помощью bleak я могу подключиться к устройству, а затем написать/подписаться на характеристики. С практически идентичным кодом, использующим pygatt, я могу подключиться к тому же устройству с помощью моего ключа BLED112, но не могу писать/подписываться на ту же характеристику.

Как видно из вывода, запись прошла успешно из-за дескрипторов ответов. И подписки явно функциональны, учитывая ответы как контрольной характеристики, так и вторичной характеристики.

Программа pygatt может подключиться к устройству (я вижу, как световой индикатор меняет состояние с мигающего на постоянное), но подписка не проходит. Я не знаю, работает ли char_write, потому что я не получаю уведомления о возврате. Я пытаюсь использовать модуль logging, чтобы узнать больше в комментариях ниже.

Обновлен вывод с включенным logging:

Я не уверен, правильно ли я интерпретирую эту информацию, но мне кажется, что подписка работает и я получаю информацию, но обратный вызов не запускается?

Я попробовал решение здесь: pygatt: невозможно выполнить device.subscribe() добавив строки time.sleep() в мой код, но вывод не изменился.

Как я могу перевести свою программу bleak в pygatt и успешно подписаться с помощью pygatt?
