I have power dropouts on elite direto trainer. Speed and cadence are ok. If I train with elites own software with bluetooth no dropouts. Heres the link one of my trainings https://connect.garmin.com/modern/activity/3188852327 edit. no beta testing.
I have a direto as well but haven't had it out in about 9 months; if I get a chance this week I'll try to test it. Just curious, care you able to install the 6.45 beta and see if you have the same issue?
I also copy my apps folder so I don't have to manually reinstall and configure settings. this makes restoring everything after I factory reset very fast.
Regarding all of your ride history you could back that up too but I usually don't bother since I already have it uploaded to Garmin connect and Strava. Plus I've generally cleared all of my write history every few months to prevent crashing, as it used to help with my edge 1000.
Jone88 - I can't view either of your rides: [h=3]It looks like you don't have access privileges to view this activity.[/h] Are you able to edit permissions or make it public?
Also, can you describe how you are set up? Are you connecting as a smart trainer and using the garmin smart trainer app? Or just doing an indoor ride and transmitting the power data? Or some type of 3rd party app (for example, I use Xert workout player to connect to the trainer)
