Bend my arm slightly bringing the V800 closer, and it regains the signal.
Sounds strange that the marginal would be that small. I need to test this, tomorrow. 6'2" myself, with a positive ape index, so we'll see. I wonder if they can adjust the receiver with software and improve this. Did you test this using a swim profile on the V800, btw?
Well, BLE HR to iPhone/Runkeeper and V800 (1.0.10) on wrist on straight arm above head at 80 cm (31") distance from top of HR transmitter to middle of watch didn't drop HR. BUT watch at fingertip distance of about 100 cm (39") drops HR after a few seconds, every time. No drop in Runkeeper, so it's not a problem with the belt. Using the swim profile in the V800 and wearing a technical shirt. Wetsuit and water might obviously affect the results, but I don't have the possibility to test that at the moment. Anyway thanks for bringing this up, rooster_russ.
Polar, is it even possible to fix this in software or is it purely HW related? I'm not exceptionally tall, so this is a real problem IMHO.
These are the same symptoms that I described a few days ago, although my setup was with the iSmoothrun app on iPhone 4S, not Runkeeper. @Lokiwthor also commented on this on June 26. In my case however, the 5Ghz HR signal would strangely reappear on the V800 after a few kms and then stay mostly stable. at least with firmware v 1.08. I did a run yesterday with 1.0.10 and that was worse ( got HR signal on the V800 for only 20 minutes out of the 57 of my run). By the way, I also noticed an impact on GPS accuracy after the update to v 1.0.10. Same exact course length 10.02km, had been measured 9.99/10.03/10.04 by the V800 with firmware 1.0.8 on 3 previous runs, and suddently 10.12km yesterday with v 1.0.10. Not much, but the V800 had so far impressed me with GPS accuracy, which I overall found spot on and certainly better than my Garmin FR 910XT. So ... putting all those symptoms together made me wonder if this couldn't come from an internal clock speed/sync problem when sampling together too many sensors, or worst the processor just struggling to cope.
Chris, by the way, sent you 3 days ago all details on the various runs as shown on my PolarFlow account and tcx files recorded from iSmoothrun, but didn't get any reaction.
The other problem reported, i.e. average lap pace being displayed erroneously (average WORKOUT pace is displayed instead) hasn't either been corrected by firmware v 1.0.10.
Is there a real chance that you guys can correct those issues through firmware update, and if so when, or will you eventually need to recall all devices ?
Besides, the key reason for me to be forced to use 5 GHz link is because there is no export facility in Flow yet. As I cannot stop analyzing my training progress with SportTracks, I must find another way to record. Hence the mandatory use of an iPhone app through Smart BLE and of the 5Ghz link for the V800. Couldn't you really field sometime like just now even a Beta utility to export tcx files ? I cannot imagine a second that all the top athletes which are endorsing the V800, nor than their coaches, can accept not being able to analyze their workouts. And this can certainly not be with Polar Flow as it is, for it is missing a lot of the most basic functionalities ... although it has several nice looking social-network oriented features.
I maybe just venting out some frustration here, but frankly I just wonder how you guys at Polar could launch the V800 with such issues not tested and at same time Export not ready ...
