import dive computer logs

Seems like there's no easy answer here from my research.

Notes: (sorry, hit send too soon):

Background: Garmin Descent Mk2i owner looking for synchronising between existing Dive Log applications (DiveLogDT or Subsurface)

Here's what I've discovered:

1. Garmin Connect (website / application) allows you to import files from the application on the watch (via the filesystem or usb link) using an import function. These files must be in the FIT format created on the phone.
2. Garmin Dive Log application (Garmin Dive) allows you to manually enter logs, or sync them from the watch directly.

My existing dive apps (subsurface / divelog) have the ability to grab data from the Garmin, but only via USB (for subsurface) - - haven't tried it for divelogDT yet.


Importing data, here's your best shot:

1. Your dive computer -> third party dive application (subsurface, whatever)
2. Third party dive application -> neutral format (csv, xml, etc)
3. Some magical (TBD) method to go from neutral format -> Garmin FIT format (if I find one, I'll come back and post here)
4. Put FIT format files into Garmin\Activity folder on the watch, and sync (or upload via Garmin connect).

This isn't exactly the smooth and simple experience I was expecting from a watch of this price.


In short here's what I think most of us would want:

1. Import my historic dives (we provide a JSON, CSV, SQL, standard divelog format XML whatever) by file upload (this should include the ability to handle all the usual diving details (depth, temperature, O2 , mix, etc) that the app currently handles + GPS coordinates etc.
2. Import my gear (don't make my type all this stuff again) - should just be a simple CSV file or similar to upload.
3. Allow me to export that data because I already manage it in another application.



For me personally, I don't really mind how this is implemented, honestly, give me a CSV download/upload option and that's sufficient. Doesn't have to be fancy APIs and an amazing UI experience (not that I'm holding my breath on that).

As odd as it sounds, the more data interchange you allow, the more likely it is that people will recommend your product because it works in their integrated lifestyle. We all have a cobbled together set of health, diving, personal, financial and lifeplan data distributed across 4 ecosystems and 17 applications,

Please don't try to replace all that with a suite of apps that's designed to be a general solution for everyone. Instead make it easy for me to get data in and out and I'll be a customer forever. 

It's 2022, and there are plenty of simple solutions that can help resolve this issue - if folks at Garmin need deeper help, please reach out. 

Hi ramjlv,

did you solved it?
Iam also looking for a solution and thinking about a kind of reverse-engineering, but therefore i need a garmin-dive.fit file.

Steps would be:

1. get a garmin-dive.fit file (proper record of a Garmin Dive Computer Mk2i e.g.). Anyone here?

2. convert the .fit file with FIT CSV TOOL to a .csv file.

3. grab my own logs and convert it with python to the same valid .csv-format i got from the original one

4. convert the new .csv with FIT CSV TOOL to a .fit file

5. try to upload it to garmin connect.

what are you thoughts?
Iam not able to write the fit file directly. Iam not into the sdk as deep as i wish.

After changing the command line i try to execute it but it stops at first 0.xml file in the sde file with the following error:
