CGM and diving

[jpip]

I think that bluetooth might work from a wetsuit (or dry) to a phone in a housing. I am diving this week but can see if it works when I get back to the lab.

Did you manage to try this in the lab?

Regarding bluetooth underwater, I wonder if smart watches with (basic) dive computer capabilities, and also CGM support-such as the Garmin Fenix series, or the Apple Watch Ultra-will work underwater to give continual CGM readings. Someone here must have already tried this.

We tried it but didn't work well at all.
Time to try it in the ocean.

If I understand correctly, the issue is that bluetooth signal does not propagate well underwater.

So, I was thinking in my particular case, if the reading device (cellphone, watch, ...) is inside the dry suit, I could still receive signal from the sense. The problem is that I cannot see the reading, but I could try with one of these (or both):

1. Play a loud alarm if glucose levels drop under a certain level (sound propagates well underwater).
2. If I had a spare dry suit that I'd happy to potentially destroy, I could cut out a piece from the forearm, patch a transparent plastic with glue, and place my phone / CGM device so that I can read the current glucose level next to my dive computer.
