Default JB4 stuck at awaiting handshake - 04-08-2021, 09:08 AM

Hi, I installed a JB4 recently on a Hyundai Veloster N

It was working for 2 days, but I now get an error when trying to connect.

It gets through all the regular steps, but gets stuck at "Awaiting JB4 handshake (1, 2... etc) then gives an error message about checking the JB4.

I'm not sure what to do, I have restarted my phone/car, reinstalled the app and still nothing works.

Also, can someone check the attached logs if possible.

Log looks pretty normal. Best to do logs for review and JB4 adaptions from 2k rpms to redline at WOT in 3rd or 4th gear.

For connection issues, that's typically a power connection or log in issue. If you continue to have issues, reach out to their support team at support@jb4connectkit.com
