Link g4+ wont connect, with no changes made

Had the ECU for a few years, worked fine around 8 months ago with the android tablet with full version of realdash. Now wont connect. ECU has not been updated at all, so its the same firmware as 8 months ago. Have followed the instructions om connections, to no avail. I can get to the Serial/USB screen, if I click that, the next screen just sticks in a loading loop and shows up nothing. Does the same on my Android phone too. Any ideas?

Send a debug log, that may help to troubleshoot this:

Thanks mate, will do as soon as I get another Tablet to try just in case that works.
