I have prepared a build of the libdivecomputer test application where I increased the timeout from 3 to 20 seconds. You can download it here. It's a command-line application, which you need to run with the following options:
[pre]
ostc3-timeout.exe -v -l ostc3.log -d ostc3.xml -b ostc3
[/pre]
Replace with the correct serial port (e.g. COM6). When done, send me the ostc3.log file. (If it's short you can also post in the forum.)

Hi Mike

For the Diving Log null reference exeption, please download this update and extract it into the Diving Log 6.0 program folder:

http://www.divinglog.com/download/DivelogTest.zip

Let me know if this error still happens.

Kind regards,
Sven

Sven,

Looks like the same error.

Hi Mike

No, my update fixed only this error below (let me know if you still get this), not the libdivecomputer error. For the libdivecomputer error, you have to download Jef's (TnT) file.

Sven,

Yes - not every time but three out of the last four tries it gave this error (below).

OK - finally solved the problem by buying a new and different Bluetooth dongle. Asus (Bluetooth 4) worked first time. So it looks like my problem was in not having an internal Bluetooth connection and choosing a Bluetooth dongle that didn't work with the OSTC / Dive Log 6.

The reference is Asus USB-BT400 Bluetooth 4.0 USB Dongle.
