shearwater Perdix AI

[Jon Gross]

One other note:

The Perdix AI uses bluetooth LE (smart?), which apparently (I'm still
coming up to speed on the  on bluetooth) requires the pairing to happen via
the software, rather than pairing via the OS bluetooth controls as 'older'
bluetooth does?

I'm reading through the libdivecomputer sources, and I'm not seeing any
reference to code that does this initial device communication, but I might
not have found it yet.

Is native bluetooth on OS X a thing in libdivecomputer, or does
libdivecomputer still require a serial port?

If it requires a serial port, then I think I'm stuck before I start, since
I don't see a way to get the device paired and a serial port set up before
trying to run the dctool downloads.
