[PSUBS-MAILIST] Vesc motor temperature display

Wed Jan 2 19:57:31 EST 2019

Hi Alan,
Apologies for the delay - I was away enjoying summer!

I mostly use the the Android app "ESC Monitor" by Ackmaniac, which
definitely displays motor temp if available (it may not be labelled very
well is all).  The app:
https://play.google.com/store/apps/details?id=ackmaniac.vescmonitor
The app and a phone in a waterproof case are what I use for monitoring via
bluetooth.  Use these instructions to get it working:
https://www.electric-skateboard.builders/t/vesc-monitor-android-app/20888

It uses a cheap "HM-10" bluetooth module, like this one:
https://www.ebay.com.au/itm/AU-2Pcs-BLE-Bluetooth-4-0-HM-10-AT-09-CC2540-CC2541-Wireless-Transceiver-Module/153251503984?hash=item23ae805f70:rk:1:pf:0

See how you go and I can help with troubleshooting if needed.

The Metr/Perimetr apps which go with the expensive dongle are excellent and
the dongle well worth the $$$ for testing.  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.

Cheers,
Steve (the Aussie one)
