Workaround to load old m5f files:
Open a m5f in a text editor, save-as with a new name, and insert the below after
"Blockly.Remotes":[],
in the end of the file:

"Blockly.RemotePlus":[{"createTime":1625241945254,"name":"M5Remote","dragAndDrop":false,"resizable":false,"color":"#fff","bgColor":"#0080FF","type":"title","id":"__title"}],

Yes, This release is a total disaster. I can't load my old projects.
@m5stack please fix it

@brunz It seems that the power lines of motor and servo ports are directly connected to the battery. So voltage is ~3.3 - 4.2 V.

Yes, that would be very useful. But currently the same thing could be "emulated" via the Button unit in UIFlow.

@ubu
Можно засунуть позиции в Map, в котором key - номер сервы, value - позиция
Потом это Map сериализуем в JSON-строку через "dumps to json" и ее уже в файл на карту
Читать - наоборот: из файла читаем строку и потом из нее через "loads json" получаем исходное Map

@zontex UIFlow 1.7.4, the bug still not fixed. This makes UIFlow completely unusable on mobile browsers.

That bug is still there. This makes UIFlow on mobile browsers totally unusable. It is not even possible to enter an API key to connect to device

It seems the value is PWM duty cycle. So the volume increases in the 0-50% and then decreases in the 50-100%.
