Frequent connection dropouts with Edge 1030

I have tried turning off edge remote (without un-pairing) and all useless sensors, but the result is still the same, and the fit file is submitted to Garmin for review

Thanks for doing a test. I'm going to check some different scenarios over the next few trainer rides and will post the results. I've already got an open support case with Garmin so will be forwarding the results & files to them too. 

That seems to add some evidence to my findings. Thanks for testing. 

I did a trainer ride without the remote paired last night & had very few dropouts. Those that did occur were of a much shorter duration than with the remote paired.

I also recorded the workout on my old Edge 1030 as a comparison & had no dropouts at all on that unit. The only difference in setups is that my new unit has the trainer sensor paired for FE-C control  So although I believe the remote pairing is causing a majority of the dropouts it seems the FE-C pairing is also having a detrimental effect 

Are you talking about edge remote?

Because I'm experiencing dropouts again when I use Laptop to control the trainer using Desktop Tacx App.

ANT+ signal from HR band to laptop is always ok, but BLE/ANT+ signal from trainer to laptop continue to have dropouts.

In the same time and session the signal from both devices to Edge 1030 is perfect, with NO dropouts.

But I have the Edge Remote connected, not because I need it, but simply because I do not unmount it from bike.

That's right I'm talking about the Edge Remote. I haven't used the Tacx app to control the trainer & would probably use the Bluetooth if I did rather than ANT+ as I don't have a ANT+ dongle

Regarding the remote connection to your Edge1030. Are you pressing a button on the remote to connect it to your Edge when switch the Edge on? Otherwise although the Remote is paired it won't actually be connected. 

I do not have the edge remote, but I still see the drop outs. I do, however, have the Di2 hood buttons set to change screens on the 1030.

Unpaired Edge Remote, test again for 30 minutes, perfect

That's a good result, the more evidence that points towards an issue with a remote pairing the better.

I've completed my testing & submitted the data to Garmin. Rather than post a load of screen shots here I'll update this post later with a link to the document I sent them 

I have responded to Garmin, waiting for a reply
