Here's the Strava from a recent trainer session. Nothing too silly. 8 min @ 155w and 2 min @ 210w for 5 repeats, bookended by short warm up and cool down @ 130w.
Here's my setup:
Original KICKR latest firmware, broadcasting speed + power over ANT+
Edge 520 latest firmware, paired with KICKR and sets target power in erg mode
Cadence from Garmin magnetless sensor
Workout created in Garmin Connect, sent to Edge 520, which runs the workout
-Power reading drops out momentarily every few minutes, as shown by the down spikes
-There's a power drop at the end of every 210w block when target power is reduced to 155w
-Biggest problem: There's supposed to be 5x 210w blocks in the workout but the Garmin lost connection with the trainer just before the last block and couldn't set target power. This continued into the "cooldown" which was supposed to set target power to 130w. I just rode out the rest of the workout at 155w. When this happened (and it has happened repeatedly in the past) I try to reconnect to the trainer via the Garmin's menus but it will keep searching for and not find the trainer. Only after powering off/on the Garmin will it re-find the trainer.
What's going on???
-KICKR broadcasts speed over ANT+ and there are no drops. The Garmin pairs to this speed sensor (separate from the trainer sensor) with no connection drops.
-No drops in cadence as well, which is also ANT+. This seems to rule out interference, which should affect all ANT+ signals (?)
-I have an ANT+ dongle and PC that I can use to test things out, but I haven't been able to navigate my way through to a good software setup. I tried Golden Cheetah for the first time today and got lost in the app.
-Is this something wrong with my Garmin, the KICKR, or both?
Please help me out of this incredibly annoying mess.
