No interface found now, post update failure.
Uwe, I'm back. I got connected to the HexNet by putting both the computer, iPad and HexNet on my hotspot. I then used the iPad to connect and download the update. It went through the process, but a dialog appeared "update failed". Since then I can connect to the HexNet either through wifi or USB, but no interface is found when I test the connection, and I only have a flashing red LED on the HexNet. I ran the LED test and while the app said it was OK, the LEDs did not change, just keeps flashing red (the single LED on the other side from the red button). I re-downloaded the application to my PC, latest version (I'd updated it when I first ran it tonight), then plugged the HexNet into the car and connected from the PC, still nothing. I'd hoped I could find a way to re-update the HexNet, but that doesn't seem to be possible.
If you recall this HexNet dates from 2014, I've not updated it since I got it. So do you have any suggestions or is my best option to return it for replacement?
