Trouble Downloading from Suunto Cobra

Post by nuttcase12 » Tue Aug 04, 2015 22:26

When I try to download my dives from my Cobra, I receive an error message:
DC_STATUS_IO

The error log states the following:
INFO: Open: name=COM4
ERROR: Access is denied (5) [in serial_win32.c:152 (serial_open)]
ERROR: Failed to open the serial port. [in suunto_vyper.c:113 (suunto_vyper_device_open)]


INFO: libdivecomputer-0.dll version: 0.5.0-devel

My Cobra is connected via a USB cable to my computer. I checked the device properties for the Cobra. It says:
Suunto Sports Instrument = Universal Serial Bus Controllers
Suunto USB Serial Port (COM4) = Ports (COM & LPT)

I am trying to connect via COM4.
My computer is running Windows 7.

Please help. I just purchased the software and this is my initial download.

The "Access is denied" error usually indicates some other application already has the serial port open. Do you have Suunto DM running at the same time?

I think I did have the Suunto application open. I will be sure it is closed and try it again. Thanks for the update!!!

I too seem to be having troubles downloading from a Suunto Cobra using Diving Log 6.0

In my situation, this is usually my backup computer. However, I when my son dives with me, it becomes his dive computer. My primary computer is a Suunto Vyper Air. Since the Cobra is normally my backup computer, I don't normally download it. However, my son went diving with me on Friday, and I want to download his dive into his log book.

I have tried to download many times, and the progress gets to differing points, and then fails. I did one download where it looked like it was going to complete, and then it failed at the end. My Vyper Air download works without problems (so far).

This one happens most frequently:
System.Reflection.TargetInvocationException: An exception occurred during the operation, making the result invalid. Check InnerException for exception details.

at System.ComponentModel.BackgroundWorker.OnDoWork(DoWorkEventArgs e)
at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument)

Diving Log Version: 6.0.0.1
Windows Version: Windows 10

Here is another one, I think this was when it looked like the download almost completed:
System.OverflowException: Arithmetic operation resulted in an overflow.

Diving Log Version: 6.0.0.1
Windows Version: Windows 10

According to the Device Manager, the Suunto driver is sated 8/26/2014, version 2.12.0.0. The first problem smells like it might be a timing problem of some sort. I'm happy to run any diagnostics or some other version of Diving Log if you need more information.

Hi

Yes, this is a problem which I'm still trying to figure out the reason for it. Please download this update and extract it into the Diving Log program folder. I can't promise this problem is fixed. Please let me know how it works for you.

Kind regards,
Sven

Thanks for sending an update to help investigate this. It looks like the same result. I don't know whether including the PDBs might help to locate the problem....

Hi Sven, I just now saw this post.

My software updated the other day, and the downloader looks much better. Still running into problems however. When I tried to download, I got this:
System.OverflowException: Arithmetic operation resulted in an overflow.

at Divinglog.Download.LibdivecomputerParser.GetHeaderValue(parser_field_type_t FieldType, UInt32 Flags)
at Divinglog.Download.Universal.ParseData()
at Divinglog.Download.Universal.LibDC_DownloadComplete(DeviceStatusEnum Status)

at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs)
at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)

Diving Log Version: 6.0.1.0
Windows Version: Windows 10

I'll be glad to help you continue to troubleshoot this.

Hi

Yes, I think I finally figured out the NullReferenceException that happened only when "Log Errors" was active. This is a new error which I'm currently tracking with another user and seems to happen only for some Suunto computers. It is happening while reading a dive header. Can you download this test build (unzip into the application folder) and run the downloader again with "Log Errors" enabled. You should see a popup error message (please copy and paste it here) and send me also this file (or attach it here):

C:\Users\Your Name\AppData\Roaming\Diving Log\Downloader.txt

Thank you for your help!
Sven
