Assuming you have skate A and skate B and they each have VESC-compatible ESCs Left and Right
(this actually won’t work on single drives 
) (assuming dual drive for everything)
- Connect a Mini Remote radio receiver to skate A ESC left
- Connect a Mini Remote radio receiver to skate B ESC left. (You could actually do this with more skates, but only with 2 remotes.)
- Connect a GT2B radio receiver to skate A ESC right
- Connect a GT2B radio receiver to skate B ESC right.
- Pick two integers, I’ll use these two. They can’t be the same. left: 37 right: 42
- Connect a bluetooth or metr module to at least one ESC per skate.
- Grab a paint marker and write “37” on a Mini Remote. Write “42” on the GT2B remote.
- Power up and pair all receivers, and set the failsafes , and set the throttle mapping and curves on every single ESC. They all need to be set.
- Connect to the bluetooth or metr with a mobile handset (with wifi connected) using VESC-Tool or metr smartphone application. Turn on TCP forwarding.
- On a laptop or desktop on the same wifi (or wired) network, connect to VESC-Tool and set all the left ESCs
VESC ID to 37. Set all the right ESCs VESC ID to 42. This is in App_Settings > General . Write the changes each time.
to change remotes
- Connect to the skate with VESC-Tool using a forwarded TCP connection
- In
App_Settings > PPM > General change both ESCs’ Multiple VESCs Over CAN setting to False and write the value. Don’t try to get ahead of yourself. Turn them both off FIRST . ignoring this can cause you to have to open the enclosure and use a USB port
- Now look at the remote in your hand, and whichever number is written on it, go to that ESC on the CANBUS, and set
Multiple VESCs Over CAN to True . Write the value. That skate is now using the remote in your hand and ignoring the other one.
So you can switch which remote is active in about 30 seconds…
