Suunto Vyper Air can't retrieve computer details

[OH]

Hi,

I am new to subsurface and started using it today. Until now I used Suunto's DM5.

When I try to configure my dive computer I hit the Retrieve available details and get an error. The log is as follows:

I am running Subsurface 4.5 Beta 1 (and tried 4.4.2 too) on Windows 10 64bit.

I am connecting my Vyper Air using the official Suunto USB cable with the Suunto USB Drivers that came with DM5. Please note that I managed to retrieve all my dives from the dive computer into Subsurface and also note that DM5 works without errors.

Following searches with suggestions also note that the battery is brand new and was replaced a week ago and the dive computer is completely dry.

Any ideas why it doesn't work?

Thanks!

So you were able to download your dives, but configuring the dive computer
fails. Hmm. Copying Anton who wrote that code :-)

It sure looks like issues with the cable. Basically the serial
communication fails. But maybe there's something I'm missing.

(Reposting here. I wasn't allowed to answer by email for some reason) 

The thing is that the Vyper Air belongs to a newer family of Suunto             

computers than the old Vyper series, and we have no support for                 

configuring those.                                                              

                                                                                

The ones that the configure code works with are:                                

Spyder, Stinger, Mosquito, D3, Vyper, Vytec, Cobra, Gekko and Zoop              

                                                                                

                                                                                

Does DM5 support you configuring your Vyper Air from it? If so it would         

be intresting to get some serial traces of that to try to figure out            

where in the memory it stores those settings and how.                           

                                                                                

libdivecomputer supports getting the device version and resetting the           

max depth, but thats it for the Vyper 2 series computers.

Hi,

I couldn't find an option to configure the Vyper, but it does manage to get data from the computer which didn't work with subsurface (reminder: the error happens after I click retrieve available details button).

OH.

It works exactly the same as for the vyper family: you write the correct
value to the correct memory address.

Some of the settings are already documented here:

This is a log from the vyper backend.

For the Vyper Air you need to use the vyper2 backend. But as Anton
already explained, subsurface supports configuring the dive computer for
the older vyper devices only.

How can I change the backend to Vyper 2? In the Configure dive computer screnn all I see are: OSTC 3, Suunto Vyper Family & OSTC, Mk.2/2N/2C.

Also just to make sure, I want to use this screen to retrieve the computer information so it is updated in subsurface (total dive time, number of dives, etc.) I am not looking to configure the computer just keep track of my usage, and this was the only place I found to do it.

Thanks,

It involves quite a bit of coding, so there is no "end-user" way of changing that. If/When we (I?) add support of the Vyper 2 Family devices it will show up in that list.

We usually don't care about what the computer have logged as total dive time, number of dives or max depth, only the dives that the diver have downloaded to their Subsurface logbook.
