Ok, so there are a lot of people having problems so sorry to add another issue.
I got the Snap about a week ago.
Day 1, I did the spind down as reccommended, and another 10 mins in. Then connected to zwift. At first the resistance seemed too high and I was putting in a lot of effort and going a fair bit slower than on my old Kurt Kinetic Road Machine. Im aware this is a dumb trainer but I ride a lot and I know what feels right for a corresponding speed/effort and it was just wrong.
Day 2, restart. Did an advance spindown, laptop off so no zwift or bluetooth connection. Seemed to be much more accurate, I felt like I was going faster than I should have been, but the power seemed much better. So I did a KISS race and was quite happy that the data was ok over a 30+k race.
Day 3, Did the same thing as day 2 and the calibration is completely wrong. Power and speed are not too bad but now i run out of gears. Its like the readings im getting from the snap dont match the difficulty of the gear im in.
Its driving me insane!!!
So here is what im doing. …
I plug in the Snap, and do an advance spindown calibration through the wahoo fitness app using Bluetooth over iphone6. I keep riding for 10 mins and do another advance calibration.
Then I close the wahoo fitness app, turn off bluetooth. Turn bluetooth back on. Open the laptop, turn on bluetooth so my zwift app can connect to zwift from my iphone 6. Plug in my ant+ for Kickr Snap HR, Speed and Cadence.
I dont get dropout so thats a positive.
I believe i have the latest firware, this updated when I first turned it on a week ago, however there isnt anywhere I can find online to check this, it just tells you it needs to update.
Is it possible that bluetooth and Ant+ are conflicting because I have laptop Bluetooth on for zwift app?
Can the app work without bluetooth?
The Wahoo utility app and fitness app seemed to give different calibration results… which should I use?
What is the correct procedure for calibration and use with Zwift?
Any help would be much appreciated.
I have asked the guys at Zwift to do everyone a favour and post a comprehensive trouble shooting guide for this but no reply.
Oh also, how often are you supposed to calibrate? This seems to vary with everyone.
My setup: Indoor bike always connected to Snap, i check the tyre pressure every use and then do two full rotations once the snap touches the tyre as in the instructions. After use I release the kickrflywheel from the tyre until the next use.
