As geauxtri suggested, I acquired the Suunto Movestick Mini. My old Garmin stick was only 1.0 but 2.0 is required for ANT+ two-way communication with the KICKR. The bonus is that this thing is so small, I can leave it plugged into my laptop all the time without worrying about breaking it off, etc.
I cannot get Trainer Road to see my KICKR unless I reboot my Mac Book Pro immediately before each workout. I got to this resolution by trial and error, and sometimes I have to reboot twice before it works -- very frustrating. At any rate, I now reboot, then bring up TR, then wait for TR to recognize the KICKR, then insert the ANT+ dongle (apparently, the MAC and KICKR must be talking to each other over bluetooth) so TR can recognize my HRM. I have found no other sequence that works.
So, am I doing it wrong? Anybody have any suggestions? It sure would be nice to have an instant connection instead of having to play with it for 5 or 10 minutes before I can start each workout.
Thanks in advance.
