Hi.
In my Kaly xlr I have a problem.
I can only see one side, or one Esc to connect to with the App.
The other one doesn’t show up when scanning so I guess it must be disabled somehow.
How can I make it to show up in the scan again?
I’m a total beginner, so please be patient with me 
It’s no concrete solution but here are some basics to go over.
Sometimes it takes disconnecting and turning off and on and trying again to work properly. That was the case with my V1 Ubox over Bluetooth, and my v2.1 completely didnt have an internal can connection until I updated firmware to 6.05. I believe there is a setting for enable / disable can bus but it is very likely on already.
If you have this one it uses a cable instead of an internal can bus thing. Also check that there isn’t a physical switch accessible through the top for the can bus like my lower voltage Ubox has.
If nothing works you could always plug into each side separately or use 2 Bluetooth modules for changing settings, is it just changing settings where you have this issue or does it not work properly?
Thanks for your quick reply.
I’ll see what I can find out.
The thing is, I just bought this board and haven’t really learned much about it at all yet.
It must be something that I have done myself because it worked properly when I got it from the buyer.
It started with that there was a fault code about over voltage but I have found that setting after a while so it’s gone now.
I know myself enough to say that sometimes I try before I think 
So I guess I just have to take my time to search in a slower pace and it will work again.
The best would of course be to be able to get back to the stock settings…
Cheers and thanks again for your input
