I'm on the latest software but not the latest firmware - my Bkool Pro is one of the older pre-FE-C models, and because I've not used it for ages, it's not had any updates.
Thing is, it won't update the firmware through the latest version of the sim, but fortunately I have the old version still installed on another computer. So I tried to update it the other day (mainly so I could use Zwift, tbh) but it kept timing out before the update was completed. Very annoying.
Hell yeah - I know I had a damn good workout last night even if the numbers suggest otherwise!
