[cepicscepics]

hi, I'm trying to ad an e-paper display to openplotter using a kindle k4. fw 4.1.3
on kindle side:
I did the jailbreak (https://wiki.mobileread.com/wiki/Kindle4NTHacking) 
I installed KUAL KUAL-KDK-1.0.azw2 (https://www.mobileread.com/forums/showpo...ostcount=1)
then KindleVNCViewer (http://www.mobileread.com/forums/showthread.php?t=150434)
but I don't know how to set it up 

when I try to connect kindle wifi to openplotter hot spot the kindle say that he can't...
I'm not able to continue...

somebody knows how ?

P.S. please excuse me if this is not the right place for that question
