hey mate if you need any help with BLDC TOOL please just let me know!
i have had a few ppl with issues of drivers causing interference.
also the latest version of bldc tool will put the vesc up the top of the drop down list.
if you still can’t connect please go into device manager and look for any devices that have yellow ! marks, if you do and its called stm virtual com port or chibios maybe even just saying e.g. COM4 then you have a driver issue.
but i also see that you are using a very old version of bldc tool.
here is the link for the latest http://vesc.net.au/BLDC-TOOL/Windows/BLDC_Tool.exe the benefit of using the latest version is it will auto install the drives that are needed when the application is installed.
you have my email if you need any more support!
P.S it wouldn’t be chukka’s vesc he makes a greta quality unit and insures the boot loader is installed
