I do understand your frustation here and if you are happy using an older version of TrainerRoad to maintain standard mode over ANT+ you’re of course welcome to continue doing so.
It appears that one of your concerns in March was the need to purchase an additional dongle to continue riding in standard mode on Windows. As I mentioned above, this has since been addressed with our support of native Bluetooth on Windows 10.
I do want to clarify that this isn’t simply us going “back to using old code”; since March, in addition to us releasing entirely new desktop applications, we’ve made quite a few improvements to how we handle ANT+ FE-C for all devices. The release of KICKR cadence was the final push needed for us to move KICKRs over to ANT+ FE-C, as the KICKR specific ANT+ profile did not support the transmission of cadence data.
Since the deprecated KICKR specific ANT+ profile no longer supported all of the KICKR’s features (this was not something that could be changed on our end), and maintaining our support for it was requiring an increasing amount of development resources, a decision had to be made - this decision wasn’t taken lightly.
We were aware that this move would remove standard mode over ANT+, as evidenced by our experiment with moving KICKRs to ANT+ FE-C in March. While we ultimately decided that March wasn’t the time, we have decided that now is the time. It is not likely that standard mode will return for Wahoo KICKRs over ANT+.
