[PSUBS-MAILIST] Vesc motor temperature display

Tue Jan 8 01:49:23 EST 2019

Thanks Steve,
yes there has been an update, but not sure what it was.
I will run the motor & Vesc on the Vesc tool & see if I can similtaneously
get a reading on the Vesc monitor. That might give me a clue!
I seldom find a good detailed manual on anything these days!
Cheers Alan

You can change the VESC configuration/settings and even do firmware updates apparently (I am running custom firmware) via bluetooth this way - saves a heap of messing about opening housings, etc.
