When the the Jb4 display froze on the app, rebooted a few times and still showed the same figures wasn't untill i rebooted the car it refreshed the figures.
Also when the app froze it didn't data log anything the logs are there but they are blank
Does anyone have any extensive knowledge of the Jb4 someone i can PM ? I've had a Jb4 before on my F82 for years and it never ever gave me a problem.

Best thing I can suggest is to disconnect the negative terminal in your battery and recheck every jb4 connection. Maybe update the software on the jb4 as well.
If that doesn't work you should email bms.
