VESC setup issues


#1

Just got my 2 new VESC’s and when i connect either of them to BLDC tool onlt COM1 says connected for a couple fo seconds and then “No firmware read response”. I’ve tried multiple versions fo BLDC and they all have the same problem. I am using two LiPo batteries in series, i know its not ideal for configuring the VESCs but its all I’ve got. i don’t have any kind of power supply. was wondering what i could do to fix it

Try the refresh arrow ( next to the connect button)


#3

Nah. Doesn’t work. And a reboot doesn’t work either


#4

Did you plug in and turn on the Vesc before opening bldc tool ?
Also you could be experiencing a com port conflict.
Try using a different com port

Your problem might be the usb wire. Change it and see if anything happens.
