HR and Speed Data Issues
« on: October 04, 2013, 12:59:03 pm »

I've used the 580 cycling computer on 10 or so rides so far.  For the most part things seem to work properly however on 2 rides I have found a problem with some of the data collected:

1) On one ride I had a spike in speed (mph) over several track points: 32.83, 79.75, 125.2, 99.59, 69.44, 38.18, 17.17 and then back to normal.

2) Then (after I upgraded to the most current firmware) I had a problem with my heart rate data as it spiked to over 200 bpm and up to 239 bpm over about 40 track points.

Can anyone explain why this might happen, is some part of my setup defective (H/W or S/W)?
What is the best way to fix the data so I can have useful information for these rides?

Thanks in advance for your help!

Dear

1) On one ride I had a spike in speed (mph) over several track points: 32.83, 79.75, 125.2, 99.59, 69.44, 38.18, 17.17 and then back to normal.

Q: Which firmware did you use??

2) Then (after I upgraded to the most current firmware) I had a problem with my heart rate data as it spiked to over 200 bpm and up to 239 bpm over about 40 track points.

Q: Which firmware did you use ??


By the way,did you use any sensor with your GD580 ?

Thank you and have a nice day :)

The firmware is F-GGB-20-1305232.  I use the speed, cadence and HR sensors that came with the computer.

Thank you for looking into this for me.

All the sensors (speed, cadence and heart rate) are the one's that came with the computer.

Thank you for looking into this problem.

Want to bump this thread, as I have the same issue as MisterMagoo.

I'm on latest firmware (F-GGB-2O-1407041 from July 24th 2014).

Only using cadence and HR sensors (both the original that came with the GB-580).

I only have problem with the HR sensor. It spikes to 240 after maybe 25-30 minutes of use, and then stays at 240 for the rest of the workout. Sometimes it goes back to normal, but not for long.
I have changed the battery in the sensor, and re-paired it with the GB580 (turned HR off, then scanned for it again).

I imported the workout in SportTracks, and this is the graph of the HR. I highly doubt that I ever was above 190bpm. Also plotted cadence, so that you can see that this sensor is always working.
As the cadence sensor is working, I guess that it is the HR sensor that is messing up.



I also have the .gpx file (or any other file-type of the workout) if this will help.

I am using the sensors from the GB580 on a Garmin 810, they work fine except if the HR strip is not cleaned with water and soap or if the battery is not strong enough. Sometimes a battery looks OK but if you put load on it, it fails. On that you can easy get high readings and it won't come down. I am not saying this is the case in your situation, but have another look.

Well, I will try to wash it properly (I'm very bad at this).

Also, last trip I had, I adjusted the strap so it was very tight around my chest, and I had good readings for about an hour. The battery is almost new, so I don't think that's the issue right now.

Going for a trip now, and will clean the band properly.

I also have a Samsung galaxy S5, with an inbuilt ANT+ receiver, but the custom ROM (operating system) I'm using doesn't support ANT+ yet, but it will soon. Then I want to try it with the phone as well.

EDIT:
Well, just finished 1h 10m trip. Not once did the HR sensor show 240bpm, so it seems like it helped a lot to wash the band. For now the issue is resolved.
