Hi,
I've bought a bafang 750W kit.
It works well, but when i connected to USB port, it was impossible to connect.
I am able to detect COM port but it is completely impossible to read flash motor memory.
Can you help me?

Make sure your battery is switched on
And make sure to disconnect before switching off battery

What port number was assigned? Some software doesn't like the higher port numbers. You can change the port numbers in device manager. For example, if the programming cable shows up as post 12 and you want it to be 2, you might have to change the other device on port 2 to something else, then the programming cable to port 2.

I have a similar problem with my BAFANG 48V 500W Rear Hub Motor Kit. I have tried to use the PC software for the BBSHD but the COM 1 or 2 (they show on the software) will not connect to the controller. I want to make some small adjustments. Any ideas to solved?
