Any luck with Mares Puck on Snow Leopard?

[lionel]

Hi,

Has anyone had any luck making the Mares DRAK interface work under Snow Leopard? MacDive detects the /dev/tty.SLAB_USBtoUART interface, but import fails after some activity on the DRAK interface (LED is blinking), and ends with a 'Cannot read memory' error. I've seen quite a lot of messages on the net about troubles getting the CP210x UART to USB to work on Snow Leopard, but nothing that could point to a solution for now. And, yeah, it works under Windows...

Console messages are as follows:

The error message "Calculated and stored size are not equal." is from libdivecomputer. Can you send me a memory dump of your device? Instructions are in this topic: http://forum.mac-dive.com/viewtopic.php?p=78#p78 Except that you need the puck application of course.

This bug has been fixed in the latest libdivecomputer code. The freedive and gauge modes appear to be different on some models. Probably because some models do not support these modes. It might be that other Mares models will need a similar fix, so let me know if something doesn't work.

Hello,

I don't know if this is the right place to post this, but I've had a similar issue (OS X 10.9.5, Mares, Smart Apnea): It seems like the download starts OK, but when it reaches 100% I get

18/11/15 17:10:49.989 MacDive[2626]: ERROR: Calculated and stored size are not equal. [in /Users/nick/Projects/DiveComputer/src/mares_iconhd.c:531 (mares_iconhd_extract_dives)]

in the console, and Mac-Dive telling me something about an error.

Or, is the Smart Apnea actually supported?

Thanks,
J.

It's not actually supported as such. Could you stop me an email?

I can have a look and get you a beta version.
