OSTC's running hwOS 
Reaching deco quickly

Hello there,

I upgraded my OSTC3 to the latest version when it was released, but since I found out that my dives are reaching the deco quickly than before and also comparing with other buddies who have OSTC or other brand.

I checked my GF with my wife, 30/80 for me 40/80 for her, but even changing this parameter I can't stay as long as she can do.

Any advices?
Thanks

Hi,

what's your setting on the Saturation & desaturation factors? If using GFs, they should be set to 100% each, else you get an extra penalty (shorter NDL, longer deco).

Hi ralf,

Both saturation set to default, 100%
I reread the manual to be sure I didn’t made a mistake.
As I wrote only GF are set to 30/80 and also tried 40/80 as my wife has.
But she don’t have OSTC, I’ll check with a friend this afternoon who has a OSTC, during the next dive.

Cheers

Hi

A higher GF low won‘t make a big difference. Just the first Deco stop will be shallower.

Best regards
Mario

Sorry for the late answer, it can be from a poor battery. During the dive I saw a battery warning but soon I finished it my battery percentage increase to 72%. one hour later, 26%...
Battery changed let see next dive.

Well, as long as the OSTC stays alive, it will do its calculations in a propper way...

I may have a big issue since 3.01 update

It worked fine for the update one month ago, but now, I put a brand new SAFT LS 14500 and it's written Batt:0% ; In system information I have 3.445 (T0)

Another thing is when it reboot (batterie replacement) it's written Successfully Update to 3.01, but every time.

So I would try to reflash my computer but I can't connect to it on OSTC Companion 3.00 beta 8 I got this message:
OSTC3 selected.
Connecting...
Bad identity reply (1)
Port tty.usbserial-A4SHCQSJ: Bad identity reply (1)
Error: Port tty.usbserial-A4SHCQSJ: Bad identity reply (1)

Any idea...

So I did a reset battery and re set to T1 3.6v disposal, all back to normal, 100%.
Also reflash from my Linux computer instead of Mac, connection OK, I could reset all things.
