well that was fun, NOT… well you’ll remember my saga of yesterday an FW 5.01 over BLE…
FAIL but didn’t appear to brick the Unity… and the board still seemed to respond to the remote…
today tried to take board for ride… Unity app sees Unity BLE and errors out… board feels like 50% duty cycle while riding…
so I’m gunna open up the enclosure and bump to FW via USB… here I go… good luck to me…
EDIT: FW 5.1 FTW
WTF
Okay, I’ve read through the thread and just want a quick confirmation. Running Unity FW 23.46 with Metr FW 5.4. Those who remember that I bricked (and unbricked) my Unity understand why I am asking 
In order to upgrade Unity to FW 5.xx I can use the latest PC VESC tool or pay for the VESC app and do it there?
… and I shouldn’t update through the Metr app nor is the Enertion app being supported anymore? I don’t mind paying for the official VESC tool at all but basically if I want to update via my phone I need to pay for the official VESC app, correct?
Thank you all who beta tested, I couldn’t afford to throw myself off and re-injure my shoulder. Thank you Vedder, Jeffery, and Frank for the collaboration and hard work! I look forward to updating and sharing my experience with the community.
Yeah, for current hyst you either don’t limit speed in reverse or choose not to have brakes. Limiting rpm or limiting speed in profiles like @Trampa suggested will cut the brakes… You can limit speed of “smart reverse” tho
I had to use the USB and newest VESC tool… but I have success now!
thanks all
I’ll definitely be going that route for this update, thanks. Hopefully @Deodand can comment about the Enertion app.
Yes the FOCBOX UI/Tool will go out of support for this new firmware. Maybe we can take inspiration from some of the convenience of the config pages, we will see!
It would be cool of you could have 2 modes in the app (beginner & advanced). The ez mode would be like the the focbox UI and advanced would be like how the vesc tool is now.
much, much, much easier to configure the board with FOCBOX UI/Tool
goin’ for that sweet HFI right now…
This helps a lot
Third time thru @Deodand’s tutirial… Plugging in da powa and USB © now…hold my beer… The next sound I hear will be hfi music!
BTW… This is the LAST TIME i experiment on a perfectly outstanding board!
Werds to live by right? Brian!
Why did i do this to myself… At least nuttins bricked yet…
You okay with the HFI setup so far?
One thing I have been figuring out is that I keep lowering the HFI cut-in erpm and each time I lower it, the skate works better. Right now I’m at
HFI Start Voltage: 22.00V
HFI Run Voltage: 8.00V
HFI Max Voltage: 12.00V
Sensorless ERPM HFI: 1085.00 (0.75mph)
…and have plans to lower it from 1085 to 868erpm next time I am in the settings… 2000 is definitely too high… but I haven’t found a value I recommend yet… and every motor/ESC will be different I think…
This in mine, haven’t played around with Sensorless ERPM HFI yet.
HFI Start Voltage: 12.00V
HFI Run Voltage: 4.00V
HFI Max Voltage: 6.00V
perhaps we can take example from other disciplines… when you first get in the VESC tool it asks you what iz your pleasure…
for example…
and the tool automatically limits your basic on screen selection process… but a simple… “advanced” button gives you any and all options possible…
I found the FOCBOX UI, cool… too the point… up and riding in a minute… but when I look at VESC tool… I see parts of the greek alphabet I didn’t know existed…
fuuk yeah… dumb down the basic interface with always the option to unleash the firmware krakken would be awwesome…
Updated to Unity FW 5.1 from FW 23.46 in about 10 seconds. Seamless. Re-configuration was slightly more difficult (perhaps just different/unfamiliar or new) but really only a small learning curve.
Tested out the smart reverse and I think the default values are good. I’m definitely used to holding the brake all the way back but I think I understand how this is supposed to be used. I also tried current hyst reverse with brake (no ermp limit) and didn’t like that but I’ll give it a try with a low negative erpm limit and see how it compares to smart reverse.
Everything is great except I lost my motor temp readings… shows up at -100˚C. Can anyone help with that?
I quit… Too mucho trabajo…mi crudo…necesito muy mas facil…m
I keep switching back to Current Hyst Reverse with Brake because Smart Reverse I just can’t seem to like. I just keep the “Don’t go overspeed in reverse” in mind any time I back up and definitely don’t back up when facing uphill… and if you do lose brakes by overspeed, start footbraking immediately before you gain any more speed
edit 2022: do NOT set an erpm limit, and do this if you want to limit speed:
