Re: hwOS TECH: New Firmware 3.29

Hi Duglum

At the first descent the OSTC did not switch to dive mode. We reached a depth of approximately 10 m. Unfortunately I did not look at the pressure gauge on the screen at this time. From this descent no data are stored in the logbook.

At the second descent the OSTC switched at 7.16 m ...

Re: hwOS TECH: New Firmware 3.29

Hi Matthias

I have updated the firmware from 3.27 to 3.29 on my OSTCplus as well as on my OSTC2 today. At the first descent both computers stayed still in the surface mode (depth approximately 10 m). My buddy gave my his backup computer (canadian one) an we started the second descent. This time ...

Re: Ladezyklenanzeige

Hallo Detlef

65535 sieht für mich nach dem Maximalwert aus den die Variable haben kann (Integer-Variable). Was passiert nach dem nächsten Ladezyklus, bleibt der Wert stehen oder springt er auf 0?

Re: OSTC Sport - Need help about display

Hello Alain

The small arrow is the surface time after a dive in minutes. The settings on my OSTC is that it switch to the surface mode after 5 minutes. If I descent after this time again, it will log a new dive.

The deco stop on 0 m for 1 minute makes for me no sense. The DTR is the time to ...

Re: Frage zur TTS

Hallo Daktari

Das hängt davon ab, was du als Wechseltiefe eingestellt hast. Wenn du beispielsweise bei einem Nx50 als Dekogas eine Wechseltiefe von 21 m eingestellt hast, geht der OSTC davon aus, dass du auch auf 21 m auf das Nx50 wechselst und berechnet die TTS entsprechend.

Re: hwOS Tech: Version 3.09 beta 4 available

Hi all

I was diving today with my OSTCplus on V3.09 beta 4 and my OSTC 2C on V3.13. The new firmware works good during the diving and also the download via bluetooth to Diving Log works without problems. Many thanks to the whole HeinrichsWeikamp team.

The only thing I was wondering a little bit ...

Hi Ralph

The built-in logbook shows the profile, the page with properties and details of the dive and the gas list (after downgrading to V3.01).

Hi Ralph

The OSTC plus write the following status in bluetooth mode:
- "Starting...Done."
- "Download mode enabled"
- "Exited"
After that, in the menue settings is the second line "Bluetooth Mode" not existing. To restart bluetooth I have to colse the menue completely and start the menue settings ...

Re: TTS is adding Safety Stop (3')

Hi all

Since I dive with an OSTCplus I'm always the guy with the highest TTS value.

I don't see really an advantage in this behavior. During the dive, in my mind I often subtract 2' of the TTS to have an equivalent TTS like my bodys computer. Furthermore, after the deco the TTS value goes ...

Ich tauche seit kurzem einen OSTC plus und habe festgestellt, dass die angezeigte No-Fly-Zeit sehr kurz ist. Beim letzten Tauchgang war die No-Fly-Zeit gleich nach dem Tauchgang 1:50 h. Der Tauchgang war auf 47 m und die Gesamtdauer war 51 min die TTS betrug 8 oder 9 min mit ...

Re: usb cable

Hi Gilles

I normally connect my OSTC 2C and my mobile phone with the same cable. My experience with USB charging cables is that some chables are designed only for charging (only the pins for electrical power supply are conneced) and not for data connection.

Do you connect your mobile phone only ...

Bergseetauchen, Tiefe Tauchmodus-Start

Hallo zusammen

Ich war kürzlich in den engadiner Bergseen tauchen. Ich hatte bei meinen Tauchgängen neben meinem OSTC 2C (V2.70) auch noch meinen Aladin Pro dabei um zu sehen ob zwischen diesen beiden Tauchcomputern grosse Differenzen bestehen.

Bei Beginn des Tauchgangs wechselte der Aladin wie ...
