Tacx T2080 genius


First of all my apologies, but I can't find a 'Genius' section.

After being stored in a closet for 2 years, I wanted to take out and set up my Tacx Genius T2080 Smart this week.

I started up the new Tacx Training app (on my iPhone) and was able to connect to the trainer.

The first thing I did is a Firmware upgrade, but after waiting more than 2 hours it just stuck on 'Reboot'. In the end I closed the app and unplugged the trainer for a while.

After I plugged the trainer back in. I was able to connect perfectly with my T2080 trainer via the Training app. But when calibrating, my speed always stays at zero.

I have another trainer, the Flux 2 and the calibration works perfectly there.

Anyone have an idea what could be the cause? By the way, I tried another phone, but to no avail.

Regards Peter
