Hello. I'm a little off topic.
In official programs under Windows OS for the MT8957s device, there is a setting "from where to read device data - from "usb" or from "com port"".
In this project, you will be able to read data only from USB.

Please help me find a way to read (and decrypt) data from the com port of this device.
I do not know the port settings, but it is there).

All this is necessary in order for the device to be located far from the computer and the data from the com port could be read by the esp module, for example, and sent to the smart home (home assistant)
