Congratulations you found the biggest bug in Unity since release, it was fixed today. I highly recommend all Unity users to update to latest firmware released today!
How does this new unity firmware work with my metr pro unity. I currently have the custom baud rate FW on my unity. Is this issue gone in the new fw?
the change log on github suggests that they have fixed the current issue and something to do with the Bluetooth
=== FW 23.44 ===
- Fixed bug with bluetooth
- Fixed bug that caused battery current limit to be per motor and not total
not in the changelog but it also looks like this update contains the code for the new trampa āsmart reverseā control mode. lots of references to
PPM_CTRL_TYPE_CURRENT_BRAKE_REV_HYST

Actually:
PPM_CTRL_TYPE_CURRENT_BRAKE_REV_HYST is Ackmaniacās āreverseā - itās there now
PPM_CTRL_TYPE_CURRENT_SMART_REV is Vedders āreverseā - not there yet
The issue with baud rate was solved, but I donāt really know if it was the right way it was solved. It feels wrong to me that UART priority is now higher than PPM priority.
from:
#define STM32_SERIAL_USART1_PRIORITY 12To:
#define STM32_SERIAL_USART1_PRIORITY 3

So getting a metr for my unity will allow for accurate vesc settings changes?? Iāve been wanting this but didnāt know how accurate or reliable it was until I read through this. I really donāt feel like taking my enclosure off every time I want to tweak my ride more!

Do it. Unity + Metr is a match made in heaven if you like to tinker with settings.

Yay!! More money to spend on my board! Thatās why itās named āThe Sarlaccā
Just like the pit boba fett fell in to ādieā, this board is the pit my money falls in to die as well!

So thatās the reason my BMS prolly blew a chip and a puff of smoke the other day and also why I always get DRV faults and small cutouts randomly, and very sporadically, while riding I betā¦ almost died the other day from one too. Jesus. So whatās the final answer on if Battery settings are for both or each motor when doing settings in the unity app @ducktaperules and is it the same on the metr pro app now or different @rpasichnyk
Also, is the only place to get the new firmware from the github?
The new firmware is included in the update to the āfocbox uiā app. So, update your app and then you can update your firmware through it.
If you want cables and pc update, I donāt know how to obtain it.
I just use the app.

Ideally you want to download the latest focbox ui app version to get to the latest firmware. 1.4 for Windows will get you just that.
The version downloadable through here is actually 1.4, it just says 1.3 lmao.

After the unity update my āmodesā are not working anymore in my metr proā¦
Settings -> Magic -> Untested Firmware if you are brave (should be okay in your case), or wait for Metr app update

Great! Thank youā¦going to do that till the original update
Battery settings were per motor.
After the new fix the battery setting is for the whole system, as it should have been.
i would expect this to be the same for both the unity app and metr.
Also i dont think this would have caused your BMS to let the magic smoke out. BMS should protect its self and the battery from whatever happens in the rest of the system. Thatās what its there for. This setting also wont cause DRV faults.
If your experiencing small cutouts i would guess these are being caused by the DRV faults. When a fault happens i think the processor briefly resets as safety measure to protect its self.

Aaaaaaannnnddddddd I just ordered one. Thanks!
Is there a possibility to implement the Voltage cutoff into Modes category for a quick swap?
I often swap between 10s and 12s and have to go into expert everytime and change it on both vescs.
EDIT : I also would assume that the Temperature of the slave vesc is wrong? Room temperature is about 20ish Celsius.
If you swap different batteries for the same VESC, I can recommend saving expert configurations and apply them.
Looks like a problem on the VESC with temp sensor

Roman/Dario (@rpasichnyk @hexakopter ) is there any plan to record the battery temperature data provided by the Diebiems? The connection is already there as you provide the accurate SOC readings of the BMS as well as the cell voltages whilst charging, how complicated would it be to also track the temperature data from the Battery and/or BMS? I have no idea how much the battery heats during riding and I think it would be a cool feature to implement. (accessing to the temperature via terminal is not so practical 
)
Thanks in advance
