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.

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.

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.

Recently we had a customer find a solution to pairing their Bluetooth device with their Nook tablet.

They found if they rooted their Nook to version Android 4.3.1 they could then enable "developer mode" in order to enable "mock locations" on the android rooted Nook.

They found that the basic Nook OS wasn't able to support an external GPS so they found their own solution to issue.

This is just an FYI for any other customers that are trying to pair a Bluetooth device with their own Nook device.

Thank you again to the customer that shared their solution to a problem they were having. Thank you!

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 have already forwarded this issue to our engineers.

I will let you know when it's resolved.


The latest Training Gym Pro_V1.80_0901 works OK, now they have to release it official.
I was wrong about the firmware, after all TGPro needed to be modified to let it work.

Hello all, the software works now with configuration sending to the device. You have to use TPGPRO Training Gym Pro_V1.80_0901 :D
Thanks to the support, but why didn't they tell us regular users and testers?????? :-\

So I managed to open my GB-580P with a razor and some gentle pulling. I confirmed I have the same issue. In fact, I can pull the pin on the left side of your pic cleanly out of the circuit board (but for some reason, not the right pin even though it's similarly loose {almost as if it were attached to something on the other side of the board}).

1st image shows I can cleanly remove the left pin.

2nd image shows what appears to be a mounting plate behind the GPS antenna. This might be what the GPS detaches from when in use. I use this GPS solely for mountain biking so it sees A LOT of rattle. I would probably try to attach it using some glue that adds a small amount of damping (i.e. cocking or similar rubber based adhesive).

Unfortunately, I don't have a torx screwdriver small enough to remove the board. I'll try to acquire one to do more digging. Are those two pins and the corresponding holes/connectors the method of connection to the gps circuitry? I'm hesitant to solder the connectors and glue the gps onto the mounting plate without confirmation. If someone could upload pics of the backside of the circuit board that would be awesome!

P.S. If you want to send me a GB-1000 for beta testing, I'd happily comply. I work as a Quality Engineer for a major auto manufacturer and have extensive experience with teardowns and quality reports.

My GB580P also rattles inside. There seems to obviously be a problem. I just opened the case on my unit ant the antenna is not soldered.

Should they be soldered or just glued so it doesn't rattle?
