Hi Kyle,

yup, no problems on the 130BCD at all. On the new Type S it doesn't matter anymore anyways :-).

Cheers

Great! Is the special Rotor tool something my LBS would have on hand if they deal with Rotor cranks all the time? Or is this something specific to the power meter that they wouldn't necessarily have?

Thanks again!

Would you consider using an ant+ stick with Trainerroad and the 910 as using two recording units in parallel?

I downloaded the latest software to my 910 but it still drops power/cadence intermittently. I just started using TrainerRoad last week so I haven't had too many reps with it but I dropped power once with that today.

It seems when I have the 910 close to the pm and in one spot (not moving around like it is on my wrist) it won't drop.

HI healthynine,

I honestly don't know about the ANT stick. From what I hear (but cannot verify) that they are not the best receiving units (as they also don't need to be). Mine, for example drops the data connection to my 910xt at times. I guess the idea scenario would be to use a Garmin Edge in parallel.

When the trainer road dropped, did it drop at the same time as the 910XT? How long did the drops last?

Best
Nicolas

Would the non type s p2m fit aero q rings? 130 54/39 or would special modifications be needed

Absolutely! Only the 110 are the ones that don't fit without modification on the existing unit.

The drops aren't happening at the same time. Today with the 910 strapped to the bars, I didn't notice that it dropped at all. TrainerRoad dropped twice but it was only for a second. I will keep trying to isolate the problem and try to find a way to borrow an Edge.

The 910 when worn, drops quite frequently, otherwise it holds on fine. I guess I'm starting to think it may be my 910, but as far as I know, others aren't having the same problem.

Do you think a master reset would help anything?

I'm having the same problem with a 910. I'll try and borrow a mates Edge and see if that doesn't drop.
Post back if you can isolate the problem.

I also experienced the drops on my Garmin 510 and am working through it with Nicolas. I used TrainerRoad as well and saw similar drops on that too. Im waiting for a new battery arrive since the P2Max died and will do one more test w/ my old Edge 500.

New Renatta battery made no difference for me.

I haven't read the whole thread so this may have been discussed already but it might help. My garmin 910 was dropping heartrate, foot pod, bonty cadence, power tap, and power2max... Everything. I had garmin warranty it last week. I got the new one and same problems. I usually stream netflix on my ipad with my Bose sound link (Bluetooth) on the treadmill and on a music stand in front of my bike while on the trainer... All out in my garage. 2.4ghz Wifi and ant+ don't play well. I changed to a 5ghz wifi freq for my ipad. Problem fixed. No drops. If you are close to a router, or have a lot of devices constantly talking to your router, then (I think) the ant+ devices will keep dropping when there is a collision, and reconnect on a different freq. You may have some sort of crazy faraday cage house that amps radio freqs... I dunno, probably not. But, stopping your router from broadcasting on a 2.4ghz and only on a 5ghz wifi signal might fix the problem. The downside is that you might have to get a new router capable of 5ghz and that, I think, not all devices can receive those freqs. If this is all irrevelant to your problems, please disregard ;).

This might be helpful. My bike is about as far away as possible from the router, but it still isn't terribly far. Unfortunately it's too cold to just try an outdoor ride.

I will have to try a test ride with the router off to see if that does anything. I'm not familiar with 5gHz so I'll try no router first.

What's interesting is if I get the 910 close to the powermeter and it doesn't move around (strapped to the bike), it works fine. Perhaps all this is doing is reducing the effect of interfering signals.

Thanks for the suggestion!

No problem. Dual band routers broadcast in 2.4 and 5ghz freq ranges. The "no router" option is the simplest Gordian knot solution... I would agree that if there is an interference issue that the closer the 910 is to the p2m that the better it will work. I'm assuming the device's antennas have a built in squelch which is probably getting broken by interference. Think of it like going on a road trip. You start to lose your radio station and pick up another. Neither are clear. Or intelligible. You go a little further one way or the other and your good to go on one or the other but not both. The frequency spectrum is a pretty busy place and low power (like ant) usually loses out to high power (like wifi).

Mine works fine indoors but has this problem outdoors

No clue about possible problems outdoors. The Garmin tech I talked to didn't seem too surprised that the radio in the watch might be bad. If it's still under warranty, I would try getting it replaced.

Thanks for your insights HereForThe Shirt. I can echo what he says. We almost only get reports of drops from people riding indoors. Many houses are very "busy" around the 2.4GHz band, which can wreak havoc on the receiving side. I, for example, have a 2.4 Ghz mouse, router, ANT+ dongle, etc. However, I never have problems with my Edge 800. Why the 910XT is different I can't tell - maybe the antenna is smaller due to the physical size or some other factor along the lines, but I am just speculating.

The 5G signal doesn't travel through walls as well as the 2., which may help. It also may just be far enough from ant+ though! I don't know anything about ant+.

A 2.6 ghz difference in freqs is more than adequate spacing to prevent interference (600mhz difference). The watch's antenna shouldn't even "see" a 5ghz signal. I think the problem arises when your ant device (like a p2m) is broadcasting @ say (hypothetically) 2.450ghz (2450 MHz) and your router is broadcasting to a device close to you or with enough power to drown your ant signal at like 2.452 ghz (2452 MHz). In my mind, a 2 MHz spacing difference should be more than adequate (especially as how tenths, hundredths, and thousandths of a MHz are distinguishable by many radios) but it appears it's not? Also, it looks like each wifi channel as an affective freq width 22 MHz wide. Which is crazy to me. I'm not going to get into the power issue because it's way to early for milliamps, watts, dbm, and Ohm's law. Plus, I need to get to the pool. Keep in mind that I'm not an engineer nor particularly science savy but I have a lot of experience working with radios. If any engineer is reading this, and I'm I'm really off track, my apologies. There's a reason why FM is referred to as "F@cking Magic". Sometimes it works sometimes it doesn't... There's like magic crystals in there vibrating and pumping out cadence, power, and heart rate... And porn or my little pony or w/e on your tablet...

It depends on the 802.11 flavor that's being used. 802.11n can support a 40 MHz width. Because it can be ~2x as wide, you can squeeze in 2x the data in to that window. This is called Channel Bonding. The problem is that in the 2.4 band you only have 3 non overlapping channels, and bonding uses 2 of them.

Well I powered off the router before my ride just now, but I don't think it did much good. I had the same issues. That being said, my PC is picking up 15 other signals. My neighbors aren't that close, but apparently their wifi signals travel pretty far. Most of them are weak signals, but there are a few that come in pretty strong.

I may need to line the walls with aluminum foil or something to make sure my 910 isn't having a problem (other than getting interference) or just wait until I can ride outdoors. It works just fine when mounted the the handle bar, but that isn't a long term solution.

When I'm feeling like trying it, I may move the trainer into the basement to see if that helps "block" some of the wifi signals I'm getting.

I'll update then...

If it works on the bars, why not just get a qd kit and bar mount? I've never tried to ride with my 910 on my wrist but I'm sure it would be a PITA.

I have a mount but it is hard for me to read while riding. I usually have the face of the watch on the inside part of my wrist and I can easy read it while aero. I can easily use the mount indoors and read it while sitting up but otherwise it is too difficult to read.

I'll figure something out.

You shouldn't have to band aid fix a $1K+ power meter or $400 dollar watch. I can understand the frustration because I have similar issues with my Rotor Power cranks. I race with my 910 on my wrist and edge 500 on the bars so I can actually all my pacing data.

I agree. You can only troubleshoot for so long. If I tried to fix it and still had problems, I'd warranty one, the other, or both.

Hi folks,

just a quick note to let you know that we are working with healthynine to pinpoint it exactly and to get him training solidly indoors :). Will keep you posted.
