I thought BT and ANT+ used the same spectrum, 2.4 GHz, which means they'd likely suffer equally from interference.

They are, but bluetooth 4.0 has something called frequency hopping. This allows it to get through when there's interference when ANT would not.

Interesting, thanks!

Cheers Nate

Am using Ant+ as I use my SRM for power control/recording.

What would be useful is some sort of bridge that would allow me to convert the PM and HRM Ant signals to Bluetooth. That way I could use my phone or iPad to control things which would be much more convenient on a number of fronts.

This reminds me of another question.

Trainerroad captures my SRM power numbers and presumably is also aware of the Kickr power number...

Does it log both? Wouldn't it be awesome if we could then generate a plot of the differential at different power levels which would inform us whether we are good candidates for the simpler offset option.

While sounding cool to me, I can imagine this would have a priority rating of close to zero for a company though. Does anyone know of a Mac compatible programme which can capture and plot two Ant power streams?

Tour de Giro can capture two ANT+ streams. PerfPro can capture two ANT+ streams. Golden Cheetah can capture two ANT+ streams. Golden Cheetah is _probably_ the best bet, since it is free.

Extra clarification: TdG can certainly do two ANT+ streams on one stick, I'm almost certain PerfPro can, I expect GC can but I'm not sure.

I agree that capturing both streams would be cool. Our device layer supports it but our UI doesn't show it :(.

I believe DC Rainmaker records the data on multiple head units then unifies them in excel. I know I know, that sounds like a PITA!

The bridge would be nice. We don't get many requests for a bridging solution and we haven't found a solution that we really like yet.

Cheers, if GC can do it that would be perfect (I have that). Will have a play.

I suspect if DCRainmaker reverts to multiple recordings and subsequent combining, there probably isn't a more elegant solution. I've never had the patience (or comfort with excel) to try and do that.

Would be a neat little utility for someone to develop and relatively simple but would be useful to such a small number of people I suspect. I completely agree this is outside the scope of Trainerroad the programme which does a fantastic job of doing what it is intended to do!

Running the Kickr with BT would be great, but just never going to be an option for me. I need to get off my butt and order one of those Wahoo iPhone dongle thingies. Still Ant+ but it will reduce one piece of hardware (the laptop) I need to set-up before every session.

when using my iphone 6+, kickr and power2max, how come I cannot get a cadence reading on the iphone running TR? I can see the cadence on my garmin coming from the power2max.

Hmm, I haven't seen that one before. I'm having a support agent email you directly. We're not supposed to do support on the forum. One thing I can suggest is closing the app and repairing. See if that gets your P2M to read cadence. If that's the case, it's definitely a bug on our side.

Just to clarify, Im using BT to connect my iphone to the kickr. The kickr is reading power from power2max. Shouldn't the kickr be transmitting the cadence via BT to my iphone?

Good Morning Nate,

same problem again, ran Charybdis+1 not long ago
https://www.trainerroad.com/.../2297968-Charybdis-1

4th interval instructions say go out of saddle, naturally cadence drops and then it grinds down very hard,
I stop, start a few times but no go, eventually interval finishes
but still cannot get back started in the rest interval, seems more aggressive in rest interval, have to quit workout.

I suggest maybe the power tracking with cadence changes should be disabled below certain cadences, eg 40-50
or give users the option as a feature to set a cadence value.

I guess I will have to restart and finish my 4 intervals after work.

Is the launch for the desktop revamp still on schedule? I'm really hanging out for it and waiting to see if it's worth continuing with TR, I'm curious to see what PP is like but the only reason I'm staying with TR is because I follow the training plans and PP doesn't have training plans to follow as far as I'm aware.

Yes, we're going to show the app at Interbike and launch a beta HOPEFULLY shortly after that. A critical bug could always happen that could push the timeline out.

Upgraded my kickr to latest firmware 1.3.32
tried using it without any power meter control on TR, Zwift comparing to my Quarq.

unfortunately for me it is still reporting the wattage higher by exactly 30w.

it would appear Wahoo has pretty much assumed everybody has a separate power meter
as they don't seem to concerned with resolving this issue.

I don't notice any difference between the new and old firmware. My Kickr is about 20-25W off from my Stages (20 minute test yesterday was 23W different in average power). I like using the Kickr without external power meter control since it is very smooth and much better for short efforts than power meter control via software, and I think setting up TrainerRoad at a constant 20W offset will be sufficient. Once I'm comfortable with that setting, I plan to take the stages power meter off the bicycle that is now mostly dedicated to the trainer and putting it on my other bicycle which will soon be built up once I trust the offset is stable.

A couple of weeks ago, I noticed that my Kickr offset was only 0-5W from the Stages, but apparently that was due to an out of true large pulley (the big black one that the belt is on) that was sometimes rubbing on the housing. Wahoo quickly shipped me a replacement pulley which was easy to install and I'm back at about 20W offset again.

Nate, TR iOS interface question for you;

If using an Iphone5s or 6, have you tested or seen reports of whether the 30pin to Lightning conversion cable ( http://www.apple.com/...39c2f92515440e4b7923 ) works well with TR?

Trying to make a custom iphone mount for the bars and its hard to get enough room to run the wahoo ANT+ stick, plus the regular 30pin to lightning adapter all plugging into each other and then the phone as it adds an additional almost 2" below the iphone and i cant find an out front mount long enough to get away with that.

PS. the new cyclocross programming is painfully amazing.

Thanks

This adapter should be good to go, since it's Apple manufactured. The non-Apple adapters are the ones to watch out for as they don't have the same 'guts' as the Apple made ones.

P.s. Cheers to CX season! ;)

I've got that same adapter, works with no issues.

Great to hear, thanks guys.

you could get you quarq to control your kickr?

Yes, via Perfpro or Trainerroad / Zwift.

ok, so i have to be using one of those app to get quarq to control the kickr?
