hwOS Tech: 2.27 released

The new hwOS Tech (for OSTC3, plus, cR and OSTC 2) firmware 2.27 is now available for download:

The firmware itself can be set to English, Deutsch, Italiano and Français. The firmware is now split into two language versions: English + German and French + Italian. Make sure to install the correct HEX file.

That's an update mainly for OSTC Plus users but it has some moniro new features for everybody, as well. This is not the stable of the 2.93beta (With a lot of changes) but "only" a stable 2.26 with some minor fixes.

Again, the important note:

Important: Saturation and Desaturation-Multipliers do now also affect the deco schedule in GF mode! Default settings will result in more deco now. Set these two multipliers to 100% to have the same deco with the same GF settings as in the old stable.

Die neue hwOS Tech Firmware 2.27 (Für alle OSTC3, plus (Tech-Versionen), cR and OSTC 2 (Bei Mod. 2017 Tech-Versionen)) ist jetzt zum kostenlosen Download verfügbar: [heinrichsweikamp.com]

Die Firmware selbst kann auf Englisch, Deutsch, Italienisch und Französisch gestellt werden. Die Firmware ist nun auf zwei Versionen gesplittet (Englisch + Deutsch sowie Französisch und Italienisch), achtet darauf die richtige HEX Datei zu installieren.

Dies ist ein update hauptsächlich für OSTC Plus Anwender. Aber auch alle anderen bekommen ein paar (wenige) neue Features. Dies ist nicht die "Stable" der aktuellen beta 2.93 (Wo sich sehr viel verändert hat), sondern "nur" eine 2.26 mit wenigen Änderungen.

Wichtig: Auch im GF-Model werden nun die Sättigunsmultiplikatoren mitberechnet! Stellt diese also auf 100%/100% wenn Ihr mit den gleichen GF-Faktoren die gleiche Deko wie bisher erhalten möchtet. Die Default-Werte sind sonst um einiges konservativer als bisher.

BUGFIX: Display of negative (°C) water temperatures
NEW: One dezimal for water temperatures below 10°C
BUGFIX: Battery handling in OSTC Plus hardware

BUGFIX: O2 Sensor readings were not updated in fixed setpoint mode
CHANGE: Minor logbook layout fix
BUGFIX: "lost gas" showed current set of gases (Diluents in CC, OC in Bailout) for both "lost gas" menus
NEW: Show Compass calibration results in Compass menu
BUGFIX: Simulator in CC mode
BUGFIX: Changing the dive mode and starting the simulator (without leaving the menu first) caused false calculations in the simulator
BUGFIX: PSCR Mode "OC Gases" showed Diluents, not OC gases
BUGFIX: CCR Mode ("First Diluent" ) was chosen based on OC "First Gas" number
CHANGE: CCR Calibration gas range limited to O2% 21-25 and 95-100 to save button presses
NEW: Show a warning for each sensor if the sensor is end-of-life after calibration (Less then 8mV in Air at sea level)
CHANGE: Minor optimizations
BUGFIX: Lost Diluent now possible in CCR and PSCR mode
NEW: ppO2 blinks in sensor mode when min/max boundaries are hit
CHANGE: Show actual GF (Not relative) in custom views in dive mode
BUGFIX: Do not check ppO2 for disabled gases
CHANGE: Apply safety margin parameters to both models (GF and non-GF)
BUGFIX: Impossible fixed-ppO2 (e.g. 1,6bar in 3m) used for tissue calculations
BUGFIX: Menu tree cleaned up (Exited to CCR menu from simulator settings)
BUGFIX: Do not show GF in divemode for non-GF deco mode
BUGFIX: Skip MOD Test for CCR in Sensor modes (OSTC cR and OSTC3 only)
CHANGE: Swap positions of ppO2(O2) and ppO2(Dil) in customview 10 on screen: "left = lean" and "right = rich"
BUGFIX: A wrong configured gas was suggested as "Better gas" on the configured depth even if this resulted in a ppO2 high or low condition
BUGFIX: O2 as diluent in CCR caused wrong calculations (Deco, EAD, END) in less then 6m depth
BUGFIX: Ignore "Toggle GF" Menu entry (in divemode) when using the non-GF deco mode
BUGFIX: Minor dive mode layout fixes in CCR Mode
CHANGE: Minor German language fixes
NEW: Warning for Diluent beeing out of safe ppO2 range in CCR modes
NEW: New Customview 9 in OSTC cR or OSTC3 shows mV readings after Sensor calibration
NEW: Third and fourth logbook page per dive showing Gaslist and Setpoints in standard font size
BUGFIX: several minor graphic issues in logbook fixed
BUGFIX: Rare button issues in OSTC Plus hardware
BUGFIX: Compass sensitivity for newer models
BUGFIX: PSCR mode showed bailout gaslist instead of diluent gaslist
BUGFIX: PSCR mode "Better Gas" showed bailout gases instead of diluents
NEW: More customviews in surface mode for PSCR mode
NEW: Last Dive customviews in surface mode with divetime, depth and interval
BUGFIX: Reset to MOD in Diluent Menu did reset Setpoint change depth
NEW: Two ppO2 max settings. One for travel/bottom and one for deco gases

Hi Matthias,

I upgraded from 2.26 to 2.93beta for testing purpose, is it possible to "downgrade" to 2.27 for real dives ?

Happy Christmas to everybody at HW !
