There is no magic. It's simply a sequence of steps.

- first you need a quiet environment (I walk out into the backyard and even there I can see half a dozen BLE devices - compared to 28 in my office)

- forget the pairing in the Windows device settings
- turn on BLE mode on the Perdix AI
- pair Windows
- start Subsurface
- scan
- download
if it works, go back to your house as likely your toes are cold.
if not, repeat

If I connected my Shearwater with a different computer or device since the last time I downloaded from it on Windows then it will take half a dozen or more of runs through this sequence.

And for your statement about "never seen anybody"... please stop spreading this nonsense.
As I have said multiple times here on this list, it works for me, and more importantly, the Windows BLE code was DEVELOPED using a Shearwater Perdix AI as the BLE dive computer to test with.
It was in fact for a short while the only one supported.

So yes, it doesn't work as well as I want it to work. But it definitely works.
