how to run two bldc motor in different direction over bluetooth uart data

i am using two vesc4.12 connected over CAN and with master i connected bluetooth. i want to rotate both motor in different direction.

when i send 255  at  x and y value. both go forward , and on 0(zero) both go backward but when i send 255 on x and 0 on y in that case also rotate in same direction.

can anyone plese tell to rotate both motor in different direction what data should i send and what setting should i do

Hi, im running a Maytech vesc 6, Fw 5.1, using FOC. When I run the motor or any detection >10A the usb connection with the vesc from the VESC tool (Win 10) stops with the error "Serial port error, a device attached to the system is not functioning". When I run a detection with low amps (flux linkage or hall sensors) no error / result is returned. Has happened with multiple cables / computers, and im unsure what could be causing it. No faults show up in the terminal. Motor settings:

I work on custom VESC based on VESC 6 plus schematics https://vesc-project.com/sites/default/files/Benjamin%20Posts/VESC_6_plus.pdf but I'm replace MCU with STM32F4 100pins and type of mosfet using https://www.infineon.com/dgdl/irfs7530-7ppbf.pdf?fileId=5546d462533600a40153563a9d1e21d8

My VESC 6 controller (Maytech) works fine connected via USB cable with the windows VESC tool.

Now I installed the Android app (via .apk file) on my Android 6.0.1 phone (Sony xperia Z3) and I finally found the correct cable USB-C (VESC) to micro-USB (Z3).

But no connection is shown, also I don't see any option for USB connection in the VESC app.

I tried "Allow USB debugging" and changing USB profile, also I set all app permission for the tool - no success.

How is the USB connection meant to be used, or activated?

Hello. I've searched the internet and the forums and cannot get a good idea if this can be done:

I would like to have my scooter use it's hall throttle, and it's brake lever for ebrakes and use the Bluetooth for monitoring.

My setup:

I have a VESC that attaches to a nano Arduino through the servo connector (which is attached to my scooter hall throttle). I use an Arduino, because I have a button that holds the PPM signal for cruise. 

I use my VESC-drive to control a rail-bound teaser-machine from a distant place. If by bad chance the RC-Tx drops out while the machine is running it will continue to move on.

Is there a setting that I did not find until now that turns the drive off or set it to minimum whenever the RC-Rx does not receive a valid signal?

This is a safety issue. Any suggestions to resolve this will be highly appreciated

Hello guys,

Can somebody explain me teh difference between the modes you can select in the PPM  mapping and when to choose one more to the other, or point me to where I can find the discussion on that topic.  I am using a Trampa VESC to control a foil board motor, which mode will fit the best and why (definitely no brake needed...)  

Dear forum,

I am new to VESC in general.

I am  a RC modell pilot since several years and a big fan of the plane Pilatus PC 6 Turbo Porter (Turboprop engine)...

I would like to simulate the startup of a real turboprop using BLDC motor. controlled by VESC...

The startup of a real turboprop can be looked up here for excample https://www.youtube.com/watch?v=tegh5BBTtIQ
