Pedals do not reveal your riding position

OK, it started working today. I did nothing differently. Guess it functions sporadically. 

I have continued to poke at this and find I can trigger positional data to save to Connect if I pause mid-ride long enough for the pedals to timeout. The Edge 840 head unit auto-pauses and speed and drivetrain also go offline. If I do this at the end of the ride it doesn't work. There must be a resumption of the paused activity with dormant sensors reconnecting automatically. (Once the pedals did not reconnect upon resuming the ride which was unexpected but this may be a separate known issue. In any case no positional data for this activity.) Not sure if culprit is pedals or Edge 840. Perhaps someone else could give this a try? I believe the pedals timeout at ~4 minutes but my last activity pause lasted 7 minutes. And 3 times before this rides with pauses over 15 minutes. In each case positional data was saved.

I continue to have the problem, only once out of 20 times I can see the data correctly. I tried moving the pedal plates, changed my posture on the bike, nothing... now I've given up.

I looked and also on the Garmin device that both my edge 1040 and the Epix reveal and I see on the device the same dynamics, so the problem comes from the pedals

Update from 2 months ago - same sporadic functionality. Not a critical function for me, but IMO it doesn't work, at least for a 145 lb guy.

lately given the bad weather I'm starting to use the indoor bike and I moved the pedals on the old bike that has 175 cranks instead of the 170 that I have on the bike that I used all summer, and magically the running position works perfectly. I don't know if this is the main cause or if it's the fact that the driving position is slightly different, but in 5 workouts it has always detected the position correctly.

I will try to go out for an outdoor ride keeping the 175 lever length and see if it improves anything, otherwise it is a matter of the riding position of the bike

Cool. I too had a recent run of 2 rides in a row with positional data recorded (best result in over a year). But back to zeros today... It is interesting we both had success around the same time. Perhaps this is a server-side issue? I did open a case with Customer Support a month or so ago. Uploaded ANT logs and screenshots and was hoping for a durable fix by now. If you continue to have success perhaps the longer crankarm is a factor. Or perhaps simply moving the pedals? I assume you are using a torque wrench?

no, I close them by hand

Took a page from your book and reset install angles but for previously installed pedals. Went for a ride and positional data was recorded. It's a sample of one but including previous successes I am now 3 for 4. This is a definite improvement but remains a bit of a mystery to me. Time will tell.

I tried to go out setting the cranks at 175, but nothing, it even detected 12 seconds pedaling standing up when I had done more than 15 minutes.
I deduce that the problem is related to the position on the saddle.
I give up now, I just hope for some update, but I doubt it
