[PSUBS-MAILIST] Vesc motor temperature display

Thu Jan 3 04:36:48 EST 2019

Thanks Steve,
I have renewed hope!
I have the 2 apps Vesc monitor & Esc Monitor. As said, couldn't see motor
temp in the monitoring list for either of them but it may appear after I have
bound the correct bluetooth to the app & configured the settings.
I have 3 bluetooth modules & was suspicious that the jaycar module which
was designed for arduino wasn't working with the Vesc. I do have an HM-10
module & I'll play around with that tomorrow.
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.
