Di2 Connection Issues

I just connected my SM-BCR2 to my laptop and ran E-Tube Project.
Even without being connected to the bike, it should do this:

  • Plug SM-BCR2 into USB port
  • Click ‘Connection check’ (E-Tube)
  • It’ll display “connect the SM-PCE1 / SM-PCE02 / SM-BCR2”
  • It detects the SM-BCR2
  • after ~15 seconds it displays the next screen, asking you to connect the BCR2 to the bike and to click ‘next’.

So if it doesn’t get past the ‘connect the SM-PCE1 / SM-PCE02 / SM-BCR2’ stage then your problem is either with the BCR2 or the USB cable. (or the computer, but you tried two different machines)
