Log results through Ergdata app vs USB logging

I'm new here and rowing, but loving my concept2 rowerg so far! Question on the the various methods of logging and what is and isn't included in each.

For the first few days, I just rowed without anything - no app connected, no USB.

Then after a few days, I decided to try out the app (android). This worked pretty well (only 1 minor connection issue 1 time), and was able to setup and upload to my online log. I noticed there were some cool graphs online and then also could download a csv of full stroke data. However, it seemed this data always set the drag factor to 0.

Today I decided to try the USB logging to see if it fixed the drag factor issue. It seemed to, and I uploaded today's workout. I thought I checked it, but maybe I missed it, but I thought there was a graph of my workout (strokes/watts/pace) over time. But I noticed the drag factor was there. So I went back to the rowerg and copied all the logged workouts from the onboard memory to the usb stick and deleted the few workouts that were logged and uploaded by the android app, and then uploaded all my workouts from day 1 from the usb. Now, I'm not seeing any charts in my workouts, it seems to have only uploaded the split tables!

So, the question is, is USB logging to a USB stick / onboard memory of the PM5 only storing split tables and not per stroke data? Did I lose all that data when I deleted the workouts that were logged via the app?

The reason I was trying to move away from the app is that it seems that with my headphones, watch, and the PM5 all connected via bluetooth, my headphones lose connection quite often during the workout.

Thanks for any info available on this!

On the PM5 and the USB drive, only very limited data is stored and no per stroke data unfortunatly. So when the dies or gets disconnected, you lose data.

That's a bummer. Guess I might have to find a different device to allow my phone to handle just my audio, and another device for the PM5 connection.

Going to different devices is not going to help with Bluetooth overload. It might make it worse because the bandwidth used is less coordinated.

Try repositioning your phone.

Most good bluetooth audio connections will grab every bit of bandwidth they can get. Nothing left. Some apps give you the option to trade audio quality for connection stability -- fewer drops but less perfect music. See if you can find a setting that works for you. Example with Spotify (https://support.spotify.com/us/article/audio-quality/) 2.4Ghz wifi will also interfere with bluetooth so if you are streaming your music to your phone then you are adding to the problem. See if downloaded music works better for you. Lowing the quality setting for streamed music reduces the WIFI load also, so has a compounded benefit.

Look for sources of bluetooth interference. Example: The fancy invertor technology in my microwave kills the 2.4 ghz frequency where bluetooth lives, so my bluetooth headset drops every time the microwave is used.

good luck.
