я пытаюсь создать свой собственный photobooth, используя instant photo printer, который использует Bluetooth и тип сублимации краски. Для этого соединение BT должно быть реализовано в коде python или node js. По сути, я планирую просто использовать системную команду. на данный момент, однако, протестировав Polaroid Hi-print и Kodak P300R, но ни один из них даже не подключен. в частности, он отключен удаленным пользователем (устройством) сразу после подключения.(На самом деле, они поддерживаются только для мобильных платформ, таких как Android или iOS)

теперь даже я путаю, что это возможно. Не могли бы вы, ребята, помочь мне разобраться?

Вот журналы btmon подключения с использованием «hcitool cc [btaddr]» ..
