Yeah, most of it is there, but it would be good to see what the Nordic
RF app says about those value handles that are inside the vendor
service.

I suspect the thing may separate interfaces for things like firmware
updates. Or something. So I'm not surprised it fails, that doesn't
look like a simple single cmd/reply characteristic.

So I do think that I'd want to see that full descriptor layout that
the Nordic app is so nice about (make sure it's fully expanded), and
if possible a bluetooth packet dump of a download if there is some
dive log software available that uses BLE.

This being an ostc, maybe the BLE details are even documented
somewhere, I just wouldn't know where.
