Hi, I’m having the same sort of problem.
I’m trying to use the Windows BLDC tool FW 1.14 for a vesc V4.10 that I recently bought from enertion.
I have downloaded and installed the VCP driver, before running the BLDC tool.
I have plugged in the USB cable from the vesc to my PC, and ensured the vesc is powered up. I get the standard windows audible response that it is plugged in.
I dont think the BLDC tool is recognising the vesc when I click on the upper “Connect” button in the top right hand corner of the screen. In the bottom right hand corner of the BLDC tool it says "Connected” for three seconds before it gets replaced with “No firmware read response” highlighted in red.
According to my windows device manager I only have a single USB port number “COM1” (the vesc is not appearing in the device manager).
I have opened the firmware tab, and then clicked on the “Read firmware version” button and I get no response. I have also tried multiple USB cables to connect it to my PC.
I am fairly inexperienced with this sort of open source technology, and if anyone knows where I am going wrong, I’d appreciate your help.
