I have in my greedy little hands a Shearwater Perdix AI computer, which Shearwater says shares the same firmware with the Perdix and the Petrel, but it will have air consumption (if equipped with a sender).
Is there anything I can send a developer that would help with support or this? I didn't see it in the list of supported computers.
Thanks!

As far as I've read between the lines, there is a new protocol for downloading data containing the pressure sensor. The old sample format have no space left for any more data to be added to it.
I guess that the new device still supports the older download protocols from the Predator and Petrel, so just try do select Petrel and download. You should get logs from your computer, but without data from the pressure sensor.

Indeed, try first with the petrel protocol to see what we get there:
dctool -v -l petrel.log -f petrel download -f raw -o dive.%n.bin <serialport>
This will dump the individual dives to disk and allow us to have a look at the raw data.

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.

The Shearwater website says that the Perdix AI requires Bluetooth LE. There is no “pairing” per se in LE, it’s just communication and looking for specific CBUUID’s or unique numbers that a peripheral advertises that it does. There are no real “profiles” in LE either so there is no "serial port profile" so no serial port for libdivecomputer to use.

Hey Janice,
Yeah, I've been coming up to speed on the difference between bluetooth LE and 'classic' bluetooth and realizing that I've been asking the wrong questions.
Thanks for confirming my suspicions.

So it looks like getting a connection to bluetooth LE devices isn't present in libdivecomputer - are there any current plans for this type of functionality to be implemented? It seems like a major addition, since there essentially isn't a Serial Port Profile in LE.

It would probably be a bit tricky to plumb bt le into libdivecomputer. It would be way easier with the custom-serial patches I wrote for Subsurface.
It would probably be simpler to do it in Subsurface, using a custom serial which uses Qt's QLowEnergy.
You could test with the Qt example http://doc.qt.io/qt-5/qtbluetooth-lowenergyscanner-example.html , too see how well the qt bt le works on your platform together with the new Perdix AI.
Then it comes down to: Do we think the protocol is the same over bt le as it was over bt spp?

We haven’t - libdivecomputer doesn’t support BLE :-) But the protocol used is the same, just a different transport.
