Subsurface & Shearwater Perdix AI

[rsingler]

Well, if Shearwater were ever inclined to put some resources into what is admittedly one of their weaker system components, I'd guess that priority has dropped to the bottom of the pile after the ridiculous rant in this forum.
I share a similar frustration in being unable to easily download dives into Subsurface via my phone in order to transfer them over to my laptop for analysis in Subsurface (because I can't download them directly - that's a Subsurface problem). It literally takes hours! Note: I am a relatively uninformed Windows user when it comes to BT, with only modest coding skills.
Add what our previous poster said regarding a legitimate medical interest in downloading information quickly in cases of suspected DCS, and I think there's good reason to ask more of Shearwater. But this whole discussion has now become an impediment to a solution, rather than raising a legitimate question.
What a shame.

I download logs into Subsurface on the Mint and Manjaro/Arch flavors of Linux. Teric, Petrel2, and Nerd2. YMMV.

Is there any way to export a log from Shearwater Cloud and import into Subsurface in Windows?

I must be doing something wrong...

Good news from divelog the post did solve their problem for the perdix sync issues they have had for the past years |clear the parings and keys| this also fixes most subsurface issues {the speed on the petrel switch requests data faster than the LE stack can provide it dumping the transmission or in the case of the shearwater app requesting a retransmission thus the delay/lag}
[better news the newer tetric line has a more robust bluetooth stack]
The issue is hardware/firmware which does not help the perdix owners after 2019 to present when they put in bluetooth4.0LE stack so best hope is clear keys on the app and pull the logs reason it is slow is the retransmission... ( will pull ethereal/wireshark logs and see if ronnie has some ideas when I catch up with him )


now am I jaded because of a use case which cannot be addressed yes.
Overall is there color and over the top rage/hate/spite in my tone yes.
Am I angry because I was chasing drivers and purpose built software instead of going after the bluetooth stack first YES! and I am equally angry with myself as I should know better! and still angry with shearwater because they have known of the issue and chose to remain silent.

I accept that and will accept the hate I get for it... as you go through life expect to find those who disagree also expect to find those who will begrudeginly accept your position and those who will keep fighting it even if the facts are clearly spelt out... For those who got my wrath undeserving I am sorry for the pain and spite I presented.

Fact: the issue is not just bound to Linux/Unix when I stand up some systems I will pull data pushing the point... ( any issue pulling to subsurface on droid or ios ) can be due to
1.) other bluetooth signals in the area ...( this is a suspect issue due to the no key/one key "reference" )
2.) recent dive recent bind and the background lock ( workaround due to partial stack )
in short it is a issue which is tied to the hardware and firmware not drivers... [on that I was wrong] once I saw bluetooth traces from other peoples failures...
3.) even attempting the bind to a droid w shearwater sw it will not detect the use of a one way connect one point limits the ability to pull logs in case of a DCS event [things which could happen, but we never are fully prepared for]

That is the main concern I have/had knowing the logs can be pulled after a [incident] on the fly from the device... is the shearwater a watchdog or a dive flight recorder / medical review tool? can the data be used to help treat a injured diver if so how do you retrieve the data if:
1.) diver is unresponsive
2.) paired device is unavailable
3.) no method to sync to another device / offload log from the dive which only sits on the device not on the paired device or cloud [ last I checked all sync operations are manually executed in a two step action with the perdix [1. start bluetooth 2. open app to sync on the paired "device"]

If I am lying or pushing a non issue let me know...
I can if needed pull divesoft/garmin data via USB irrespective of some software package those vendors provide and to multiple endpoints...

The main point being if I took a DCS hit or a dive buddy took a hit the logs can be pulled and sent with the diver to the chamber or the hospital. The concern is can data be pulled from a perdix2 if a person takes a DCS hit and that is the only "operational device remaining" their flight recorder...

Using the bluetooth or bluetooth4.0LE?
I know the petrel can support a usb/serial link I also believe the NERD tetric also support USB connections.

What seems to be somewhat working for me is this:
From Shearwater cloud Select File -> Export ->As UDDF (Universal Dive Data Format)
Then import that file in Subsurface and some data (including the dive profile) gets imported. Other important stuff (eg O2% etc) are not, but those shouldn't be difficult to manually input.
There might be better ways doing this.

if you have a ouput from subsurface ( any format ) and a similar output for the same dive from shearwater I will do a field align and post it here so using sed awk we can realign the fields to properly format I can then build a transform script and see if it will parse the complete shearwater output into a subsurface format for a clean digestion into subsurface DM it to me if you fell open to do such

My mom told me not to take scripts from unknown people online

In a more serious note, I do all my dive logging in Subsurface. I bothered to open Shearwater cloud just to help @rsingler. Hence my shearwater cloud contains only the very basic info (things downloaded from my DC). Since you are going to do it, maybe you'd better do it with "richer" dive(s) eg with AI, more mixes (I only do single nitrox dives) and with extra manual input info (like equipment, location, conditions etc etc), so that you can work on those too.

I 100% agree... lol and as for the scripts they will be open for others to improve on ... text first then a python version then a compiled version when the fields are confirmed ( stable ) || I should have got the BT cleared on my perdix so I can attempt with this old droid unit to upload and pull back it will have some deco dives with 3 gasses ( some nitrox only layouts would be good for single gas comparison )
I have a single AI air dive in japan on there plus other deco versions... I can populate the fields for gear and location/notes in the cloud .. on my side when it comes to a mass import that is where I will need to see what fields land where..
