I have been a Garmin user for many years, going back to the original Forerunner, and now using the Fenix 5 and Edge. I have often used multiple devices to record workouts, usually a web based application along with my Garmin device and always had to choose which application to save. Now that I'm doing more biking than running, I'm using the Edge and the Fenix and it's a little annoying that Garmin Connect sees the input from these devices as two separate activities. It seems that Connect would give an option to combine these activities or recognize that they are the same activity occurring at the same time. I'd even be willing to pay for a premium service that would give an option to do this. I"d like to be able to record the heart rate and fitness data from the Fenix and the other activity metrics from the Edge. Doesn't seem like it should be that difficult to do.
same issue. Fenix 5 and Edge 510. Edge aktivitis shows in connect but can not combina heartrate and ride. Fenix dosen't know that have been riding (and maybe been counting steps?)
I found a solution of sorts. I am now using the the feature of the fenix to broadcast the heartrate and then pick that up on the edge and just record a single activity on the edge. It does help for previous rodes, but it does for those time I forget to pack my heart rate strap.
You can do this at https://gotoes.org/strava/Combine_GPX_TCX_FIT_Files.php. It allows you to upload multiple fit files and then select how to merge. For instance heart rate readings from watch, combined with power, cadence, speed, GPS from Edge unit.
I don't think you will get any changes to how this works. If you use multiple devices you will get multiple activities. Starting to merge activities is not an easy task and there are lots of potential issues that can occur. I don't believe that the heart rate data logged without an active activity is enough detailed to be used. There are a lot easier ways to fix this.
The heart rate can be broadcasted from the wrist watch to the Edge or use a chest HRM strap with the Edge. Or use the wrist watch as your main device and log everything with it and use the Edge just for navigation and viewing the data from the sensors and discard the activity on the Edge after the ride.
