Garmin descent G `2

[Jean REMY]

Bonjour, j'utilise Subsurface depuis plusieurs années même si je ne plonge pas beaucoup. Avant je devais bidouiller avec mon Aladin scubapro avec un port IR (infra-rouge), alors je me suis acheté le Garmin D'escient G2. Avant de l'acheter, j'ai bien vérifié dans la documentation Subsurface, les ordinateurs pris en charge, et Garmin en fait partie. Maintenant que je veux coupler mon nouvel ordinateur de plongée avec mon téléphone IOS, mon iPad, ou mon Mac, les ordinateurs de plongée Garmin n'existe plus dans le menu déroulant, la liste.. Si vous savez qu'est-ce qui se passe, merci de me le dire. Je vous remercie d'avance.

Garmin dive computers have never (and most likely will never) be supported on iOS or Android.
A quick search in the Forum or the documentation would have shown you that part of the information.

The issue on the Mac is interesting - I use a Garmin Descent mk2i with Subsurface on macOS reasonably frequently, but I'm not familiar with the G2.
I assume this one presents itself as a mounted directory under /Volumes when connected to your Mac?

Can you tell us more about which specific version of Subsurface you are using?
And can you explain what you mean by "les ordinateurs de plongée Garmin n'existe plus dans le menu déroulant, la liste." -- because Garmin computers most definitely show up in the drop down on current versions of Subsurface...

This screenshot is from my Mac and it explicitly mentions the G2...

I have a Garmin Descent G2 which I use on a Mac with Subsurface.

The G2 does not show up as mount point but it works just fine. I have no new dives to import but it successfully connects to the G2 and I don’t have to do anything special.

I should have added that sometimes I need to shut down Garmin Express Service (which I do from Activity Monitor) as it sometimes it grabs the G2.

Hello again, it's me again, after fiddling with the PC, my Mac, my iPhone,... I went to Garmin Connect on the Internet, from there I was able to download my new dives, which I can export in .zip format, on the .zip download I click twice and it transforms into .fit format, and this file is compatible with this Subsurface. Anyway, I managed to add my dives to Subsurface, now I have two different dive logs, a bit silly but that's how it is, nothing is perfect. Thank you for the help you gave me. Best regards and have a good day.

First of all, thank you to those who responded to me. I see that indeed there are differences between your possibilities and mine. So I will try to send you screenshots so that you understand. Of course my G 2 works with the Garmin dive inn application, but in principle I like open source, plus Subsurface has worked very well for me for several years, when I was using Ubuntu & Windows.

Version iPhone: 6.0.5581 

From my iPad same problem.

From internet, normaly the version is the last... V6.0.5576

with https://subsurface-divelog.org/supported-dive-computers/, you can see that the Garmin are in the doc

while wanting to answer you, I noticed that on the Internet there is the Garmin option, but as there is no mounting point, it was impossible to download the dives. In addition, I admit that I especially wanted it to work via Bluetooth, so that I could directly download the dives on the phone, iPhone, possibly iPad when I travel. So I sent you a screenshot, error, since it doesn't work over the Internet either. thank you.

The following is true for all current Garmin dive computers and Garmin fitness watches with dive support:
- NO support at all on iOS or Android
- NO support for BLE downloads
- they are supported on Windows/macOS/Linux, but often the direct download runs into issues because of the way Garmin has implemented that connection

Downloading on your computer with the Garmin app and then importing the FIT files into Subsurface should always work - if not, send us a FIT file where the import fails with a screenshot of the dive from the Garmin app in order for us to figure out what's going wrong.
