VESC v6.05 Firmware Advisory
v6.05 is perfectly safe - BUT you need to be aware of a few quirks
PSA #1: Bug(s) in VESC App v6.05 (especially iPhone version!)
PSA #2: Nosedive bug in UBox v6.05 firmware (fixed in Android version)
PSA #3: Nosedive setting in all controllers!
Issue #1: Bug in v6.05 iPhone App
Anyone with the latest v6.05 app (by now it’s most of us, Android users can side-load an old apk if they want) - when connecting to your board make sure you explicitly press the Read button for Float Cfg / Refloat Cfg if you want to make changes.
The app has a high chance of silently failing when trying to read your package config - if you then make a change and hit write you’ll end up with ALL DEFAULTS in your package config.
Happens with any 6.0x firmware!!!
Just last night I tried setting “disable moving faults” during a group ride and got hit with an all-default Refloat Cfg… Luckily I had a Backup!!!
Issue #2: UBox Firmware Bug
All Spintend UBox users, careful when upgrading firmware!
Fix is Available, see Syler’s (devnull) comment below!
The Spintend UBox v6.05 firmware has a serious issue with the auto-shutdown behavior potentially shutting you down even while riding!!! Do your research before upgrading!
In case you didn’t know, Spintend Ubox is a VESC controller. If your board has a different controller (e.g. Floatwheel ADV200 or others) then you aren’t affected!
Issue #3: Nosedive Setting
On some boards the erpm readings will be way off when migrating from 6.02 to 6.05 firmware. They’ll read 10-50x lower than they should.
To fix: set Speed Tracker Position Source to “Corrected Position” which is the new default in v6.05!
How to downgrade to VESC 6.02 (or prevent update)
How to disable Auto-Update of VESC Android App:
- If you are on Android, go to the VESC Tool page in Play Store, hit the 3 dots on the top right and untick the “Enable auto-update” box
- If you are on iOS, should be similar in the App Store app (can anyone report?)
