@glyphiks told me the same thing but Im quite certain I tried that. I’ll give it another shot.

Ah well. Worth a try. Your problem sounded similar as I could see the remote connected showing everything but it didn’t turn the motors until I went through the NRF wizard. Felt like I changed every possible value everywhere else before that. I found it strange I had to go through NRF wizard to make it work.
I doubt you’ve got RX/TX the wrong way around if you can see the battery level and connection on remote, but that’s the other big one (as you probably already know).
Well, my case is special. It’s a CANBUS remote that uses the vesc remote app.

Issue:
VESC turns on, lights come on, no connectivity to motors or USB, no responsiveness from inputs.
Story:
Last night was out riding on my D75, everything seemed fine, came to a stop and the motors wouldn’t spin.
Turned the VESC off and on again. Still nothing.
Metr wasn’t responding either, no BT/UART connectivity.
Got home and opened the esk8, plugged into the D75 and couldn’t connect in VESCtool either.

Is the running light (green light) on?
After running motor detection and the input wizard my brakes are sooo weak and can’t get smart reverse to work. I’ve tried really high (i.e. very negative) motor and battery regen with no success, any ideas?
Edit: at what point is bumping regen just not going to do any more?
@YUTW123 this same thing literally just happened to me on 2 units over CAN…No connecivity in VESCTOOL for either unit, by bluetooth or laptop USB. Green light appears to be off now.
Extra context:
I did run motor detection multiple times successfully with this setup in the process of getting it all put together. The last thing I did was unplug the VESC so I could wrap the cord with nylon sleeve. Did that successfully, then plugged VESC back in, and applied the hot glue to the.connectors.

I ran into connectivity issues as well when setting up it seems so random, mine were all via usb. Sometimes only one side would connect and the other side wouldn’t, other times no side would connect, and sometimes it would connect but couldn’t detect the other side via can. But just kept trying and eventually it remains connected.

I noticed this too. For my setup it just ends up taking a while to engage.

for the canbus cable only run CANL and CANH. I dont think that can fry it, but I do know that you shouldnt plug it in. I cant really help past that

As far as I remember the green light did come on, but a couple times it didn’t and it was because I ran gnd to can port and 5v to ppm port. And the other time was 5v and gnd to ppm port but backwards to a receiver.

Uhhh. Hmmm, im gonna aasume all my pin ins/outs are good cuz i passed motor detection fine prolly 5x

Yep looks like you’re in the exact same situation as I am. You described the issue much better than I did.

I have noticed that sometime on dual ESCs other than Stormcore the CAN ID gets changed to the same number on both channels. So what you can do is go in and change the can ID to any random number and you’ll notice the other can ID device will pop up upon power cycle

I’ve had this issue, but only on the D75 (2nd+ batch)
No other ESCs including FSESC6.6 plus and non-plus and DV6 varieties as well as a DIY VESC4.12. just the D75.
