New Edge 830 Public Beta 3.55 Now Available

No, in fact mine is reasonably close to my old Edge 1000 in accuracy. For example, here's a couple of nearly identical rides that I do with our younger riders, one with the Edge 1000, one with the Edge 830:

As you can see, both they are pretty close (8% difference). For comparison, a quick plot on plotaroute suggests that this route is around 1700ft climb, so we're in the right ballpark.

The 830 trace was with the non-beta GPS firmware and 8.50 (non-beta) software, as this was recorded last week before the beta came out.

It's first time for me that it is obvious that elevation figures are not correct. The only difference is that I'm using FW 3.55 now. Before elevation figures seemed to be reasonable so that I haven't really questioned these.

Updated to 3.55 beta, I was thinking, I have iOS13 beta, let's go all the way.

Well, what a mistake. Nothing works, even much more than usual :) Garmin Connect cannot pair with Edge 830.

I can pair with 830 in BT settings, but then iPhone says "accessory not supported".

Good job everyone... that's Beta life

As it happens, I repeated an identical ride this morning with the 3.55 firmware, so can compare with the Edge 1000:

Even I'm impressed with how close these match, more by luck than by judgement, I'm sure!

me too. same probleme here since install 3.55 Beta

Same here, after installing 3.55 no correct elvation totals. Attitude measurement is correct, but total over the ride is almost two time as it was with the previous version

First ride with update seemed fine.  But twice now, after I leave it on my charger for a few hours, I can't seem to get the device to wake up.  I have to long-press the power button for 10+ sec to get the device to turn on.  I could understand a long press (2 sec) but not sure why this is?  It didn't do it before the update.

Installed 3.55 Beta two days ago out of frustration with 3.50 bugs.  It might have fixed some bugs but there still are so many. Here are a few...

1.  Max heart rate still resets to something incompatible with life with jersey flapping even though Auto Detect Max is disabled.  Time in heart rate zones is then meaningless.

2.  Gradient displayed is randomly up to 5% more or less than older Edge units.  My unit has never been wet and opening the USB cover makes no difference.  My impression is that gradient displayed is more inaccurate if a course is either running or has been running and then stopped and is more inaccurate with 3.55 than it was with 3.50.  Total elevation gained is pretty accurate and the profile shown in the activity later is pretty accurate.

3.  Displayed elevation is not accurate and drifts way too much when a known elevation is entered.  My Edge 800 is  much more accurate and stable

4.  Navigation is absolutely hopeless.  I've created courses and downloaded either from Strava or RidewithGPS and installed either FIT or TCX files but none work.  If the default Turn Guidance is left enabled the top panel of the map display that should show what street  is upcoming and distance to next is blank but if I open the cue sheet there are bogus distance to next listed in 10 meter intervals but no actual turn instructions.  I expect if I left the course running I would end up with a huge unusable FIT file as happened often in version 3.50 and is listed as fixed in 3.55.  If I disable turn guidance I get no guidance at all and although the next street is sometimes listed at the top of the map, there is no distance to next and no guidance.  Unfortunately navigation that worked pretty well on my old Edge 800 does not work at all  on the 830 with 3.55.

5. If a course is running the elevation profile does not auto zoom to show a readable profile.

There is a lot to like about the 830 but there are so many frustrating bugs.  I used to think that my old Edge 500 and 800 were expensive toys and I'm thinking the 830 is the same.

After the update, my first ride worked ok as far as connection to the phone.  The only issue I had was that it didn't connect to my speed and cadence sensors initially.  I tried manually connecting but it didn't work.  It connected by itself once I started moving.

But the next ride I had the behavior that you describe.  The ride wouldn't save.  I tried manually but the upload option wasn't there.  The 830 wasn't connected to my phone.  I had to remove everything from GC, the phone's blue tooth and the 830's connection and start over.  Re-pair the phone and run through the setup.  Once I did that, my phone sync'd and my ride updated.
