Bug: huge distance in the first ride after a flight from Switzerland to China

I bought my edge 830 from wiggle.com and got it in Switzerland. After dozens of riding in Switzerland, I went back to China in my holidays.

However, it shows over 10000km in my first ride in China, which I think is the distance from Switzerland to China + the actual riding distance, and resulting in an impossible avg. speed.

Please fix this bug.

I'll should mention that when you travel large distances like that, the GPS unit doesn't know it and can take awhile to locate satellites and figure out where it is. In the past it's taken some…

You can also upload the ride and crop the affected end off in Strava...assuming the problem lies at the beginning or end of the activity.

I'll should mention that when you travel large distances like that, the GPS unit doesn't know it and can take awhile to locate satellites and figure out where it is. In the past it's taken some of my units 10+ minutes to do that. I would assume the newer 830 is faster at that, but that might be related to your problem.

Hi, this is the file.

This bug should be fixed in the firmwire instead of by users everytime it occurs.

alanyu - your issue was not caused by a software bug but rather by your own doing by not ensuring that your device had a solid GPS lock before pressing the start button. It took just over 3.5mins for your device to work out where you were and record a GPS position.

Issue fixed by removing the first data record - give this file a try.

cheers

If you don't have a new .epo file on the edge, it has to do a full scan for satellites. I think this can take up to 12 Minutes, due to technical reasons in the standard.
