<div class="paragraph"><p><span class="big">MANUEL UTILISATEUR de Subsurface-mobile</span></p></div>
<div class="paragraph"><p><strong>Auteurs du manuel</strong> : Willem Ferguson, Dirk Hohndel</p></div>
<div class="paragraph"><p><span class="blue"><em>Version 2, décembre 2017</em></span></p></div>
<div class="paragraph"><p>Welcome as a user of <em>Subsurface</em> and <em>Subsurface-mobile</em>, advanced dive
logging software with extensive infrastructure to describe, organize, and
interpret scuba and free dives. <em>Subsurface</em> offers many advantages over
other similar software solutions, including compatibility with Windows,
macOS, Linux (many distributions), Android and iOS. In addition,
<em>Subsurface</em> is open-source software that allows downloading dive
information from many dive computers.</p></div>
<div class="sect1">
<h2 id="_présentation_de_subsurface_mobile">1. Présentation de Subsurface-mobile</h2>
<div class="sectionbody">
<div class="paragraph"><p><em>Subsurface-mobile</em> est une version mobile limitée de <em>Subsurface</em> qui vise
les smartphones Android et iOS et sur les tablettes, qui permet de
visualiser, entrer, partager et stocker des informations de plongées sur les
sites de plongées où un ordinateur n&#8217;est pas utile. Alors que la version de
<em>Subsurface</em> pour ordinateur affiche bien plus d&#8217;informations détaillées
pour chaque plongée, la version mobile permet un accès facilité lors sur un
voyage de plongées, utile pour prouver une experience de plongées aux clubs
ou pour revoir les plongées précédentes. <em>Subsurface-mobile</em> permet
également de collecter des positions GPS où sont effectuées les plongées.</p></div>
<div class="paragraph"><p>Les utilisateurs de <em>Subsurface-mobile</em> utilisent habituellement
l&#8217;application mobile en tant que compagnon de la version de <em>Subsurface</em>
pour ordinateur, partageant les informations de plongées entre les versions
mobile et de bureau. Cependant, <em>Subsurface-mobile</em> peut également être
utilisée de façon indépendante de la version de bureau et ne requiert pas
l&#8217;utilisation du stockage cloud.</p></div>
<div class="paragraph"><p><em>Subsurface-mobile</em> permet de :</p></div>
<div class="ulist"><ul>
<li>
<p>
Télécharger et stocker les informations de plongées en utilisant le cloud
  <em>Subsurface</em>.
</p>
</li>
<li>
<p>
Visualiser ces informations sur un périphérique nomade.
</p>
</li>
<li>
<p>
Créer et ajouter manuellement de nouvelles plongées à votre carnet de
  plongées.
</p>
</li>
<li>
<p>
Télécharger des données de plongées directement depuis plusieurs ordinateurs
  de plongées.
</p>
</li>
<li>
<p>
Modifier de nombreux champs des données de plongées, comme le moniteur, le
  binôme, l'équipement ou les notes relatives à la plongée.
</p>
</li>
<li>
<p>
Enregistrer, stocker et appliquer des positions GPS des plongées.
</p>
</li>
<li>
<p>
Visualiser les positions des points GPS enregistrés et des plongées sur une
  carte.
</p>
</li>
</ul></div>
<div class="paragraph"><p>Ces points sont détaillés dans la suite du manuel. <em>Subsurface-mobile</em> ne
supporte pas le téléchargement des données de plongées depuis tous les
ordinateurs de plongées que supporte la version de bureau. Cette limitation
est due principalement à la capacité d&#8217;accéder à plusieurs types de
périphériques sur deux plateformes mobiles. Une partie des ordinateurs de
plongées utilisant une interface USB FTDI ou une interface Bluetooth /
Bluetooth LE sont accessibles depuis  <em>Subsurface-mobile</em>. Sous iOS, seul
les ordinateurs de plongées basés sur le Bluetooth LE sont supportés.</p></div>
</div>
</div>
<div class="sect1">
<h2 id="_installer_em_subsurface_mobile_em_sur_votre_périphérique_nomade">2. Installer <em>Subsurface-mobile</em>  sur votre périphérique nomade</h2>
<div class="sectionbody">
<div class="paragraph"><p>Vous trouverez <em>Subsurface-mobile</em>  dans <em>Google Play Store</em> ou sur <em>iTunes
Store</em> d&#8217;où vous pourrez les installer. Veuillez boter que les deux
contiennent également l&#8217;ancienne application <em><em>Subsurface</em> companion</em>
(utilisée uniquement pour enregistrer les points GPS). Vérifiez que vous
installez bien  <em>Subsurface-mobile</em>.</p></div>
</div>
</div>
<div class="sect1">
<h2 id="_utiliser_em_subsurface_mobile_em_pour_la_première_fois">3. Utiliser <em>Subsurface-mobile</em> pour la première fois</h2>
<div class="sectionbody">
<div class="paragraph"><p>Lorsque vous exécutez <em>Subsurface-mobile</em> pour la première fois, un écran
d&#8217;accueil Subsurface est affiché pendant le chargement. Sur certains
périphériques, cela peut prendre plusieurs secondes. Après le chargement,
l'<em>écran d&#8217;informations de connexion au cloud</em> apparait (voir l&#8217;image
ci-dessous, à gauche).</p></div>

</div>
</div>
<div class="sect2">
<h3 id="_when_not_using_cloud_storage">3.1. When NOT Using Cloud Storage</h3>
<div class="paragraph"><p>Tap the "No cloud mode" button. The app will not access the <em>Subsurface</em>
cloud storage server to obtain dive log information. This means that dive
log information is stored on the mobile device only. If no dives have been
entered into the dive log yet (the usual case), an empty dive log is
created.</p></div>
</div>
<div class="sect2">
<h3 id="_using_cloud_storage">3.2. Using Cloud Storage</h3>
<div class="paragraph"><p>The <em>Subsurface</em> developers provide a custom free Internet cloud storage
account that can be used for storing dive log information. This cloud
storage account can be created either from <em>Subsurface</em> on the desktop or
<em>Subsurface-mobile</em> using a mobile device; you can do full maintenance of a
dive log from <em>Subsurface-mobile</em> alone. By using the same credentials wirh
<em>Subsurface-mobile</em> and <em>Subsurface</em> for desktop, the <em>Subsurface</em> cloud
storage allows you to share your dive log between both (or even more than
two) devices.</p></div>
<div class="paragraph"><p>The dive data are cached both on the mobile device as well as on the desktop
- it is easy to create backups of the data (for example in XML format) on
the desktop, and both mobile device and desktop keep a local copy of the
data so that the dive log is always accessible, even without Internet
connection. The Subsurface team never accesses a user&#8217;s dive data without
explicit permission to do so, the data are not used for any purpose other
than providing them to the user who created them. There are no ads and no
harvesting / analysis of the data stored in the Subsurface cloud storage.</p></div>
<div class="paragraph"><p>Enter an e-mail address and a password in the fields indicated on the
screen.  The e-mail address should be in lower case and the password should
contain a combination of letters from the alphabet (upper and lower case)

set up an account from the <em>Subsurface</em> desktop application, enter the same

connectivity, <em>Subsurface-mobile</em> accesses the cloud-based dive log to
verify that the local copy of the dive log is still the same as the log in
the cloud server. If not, the local copy and the copy on the server are
synchronized.</p></div>

<h2 id="S_Download">9. Download dives from a dive computer</h2>
<div class="sectionbody">
<div class="paragraph"><p>The download deature supports only a limited number of dive computers. On
Android devices these are typically dive computers using an FTDI interface
using a USB OTG cable (but this is blocked on some Android devices by OS
settings). Android devices also support all Bluetooth dive computers that
are supported in Subsurface. And both Android and iOS devices allow direct
download of dive data from a hand full of Bluetooth LE enabled dive
computers.</p></div>
<div class="paragraph"><p>Use the <em>Vendor name</em> and <em>Dive Computer</em> drop-downs to pick the correct
dive computer. When downloading from multiple different dive computers,
shortcut buttons to easily switch between them will appear below the
drop-downs.</p></div>
<div class="paragraph"><p>The process for download is slightly different between the two OSs.  In our
testing we got the best results on iOS when the dive computer was in
Bluetooth mode before <em>Subsurface-mobile</em> is started. On most dive computers
this is done through a menu entry, others (like the Suunto models) always
respond to BLE requests.</p></div>
<div class="paragraph"><p>On Android devices, you should first establish a link between the Bluetooth
or Bluetooth LE dive computer and the mobile device using Android
utilities. See below for more details.</p></div>
<div class="paragraph"><p>For USB dive computers, USB cables "normally" used for uploading dives to a
desktop/laptop computer do NOT work: these cables usually have a full-sized
("Type A") male USB plug on one end which plugs into the USB port of a
desktop/laptop computer. For downloads to a mobile device one needs a USB
OTG (USB On-The-Go) cable. In most cases it is required to plug the USB
cable "normally" used with the dive computer into a USB OTG cable which, in
turn, plugs into the mini-USB (or sometimes a USB "Type C")  receptacle of
the mobile device. The OTG cable usually has a full-size ("Type A") female
receptacle at one end which accommodates the full-sized male plug of the USB
cable "normally" used (see image below). This means that two cables are used
to connect the dive computer to the mobile device.</p></div>
<div class="paragraph"><p>Please note that not all Android devices support OTG cables. And even on
some devices that do support those cables in general, <em>Subsurface-mobile</em>
still in some cases cannot access a dive computer through a serial port.</p></div>
<div class="imageblock" style="text-align:center;">
<div class="content">
<img src="mobile-images/USB-OTG.jpg" alt="FIGURE: USB-OTG cable" />
</div>
</div>
<div class="paragraph"><p>For Bluetooth-equipped dive computers and Android devices, establish a
Bluetooth connection between the dive computer and the mobile device. Use
the tools on the mobile device to achieve pairing between the Bluetooth dice
computer and the mobile device. For of Android devices, the Settings &#8594;
Bluetooth tool is probably appropriate. Ensure pairing of the dive computer
and mobile device.  <em>Subsurface-mobile</em> performs communication using both
Bluetooth and Bluetooth-low-energy (BTLE).  The appropriate choice of
Bluetooth communication is made by the software and the user need not be
concerned with this.</p></div>
<div class="paragraph"><p>With pairing between dive computer and <em>Subsurface-mobile</em> having been set
up, dive download is simple.  From the main menu, tap <em>Manage dives &#8594;
Download from DC</em>. A screen is shown requiring that the user specify the
names of the vendor and model of the dive computer. For instance, when using
a Shearwater Petrel 2 dive computer, the vendor is <em>Shearwater</em> and the Dive
computer name is <em>Petrel 2</em>. From the two dropdown lists at the top of the
screen, select the correct vendor and dive computer names (see image on the
left, below).</p></div>
<div class="paragraph"><p>Now tap the button labeled <em>Download</em>. The downloaded dives appear in the
bottom part of the screen, the most recent dive at the top (see image on
right, below). Be patient because the download can take a few minutes.  As a
matter of fact, a complete first download from some dive computers has been
shown to take 45 minutes and longer.</p></div>
<div class="paragraph"><p>After the download, each dive has a check-box on the left hand side, used
for selecting which dives you want to be added to the <em>Subsurface-mobile</em>
dive list: dives that are not checked are ignored. With the appropriate
downloaded dives having been checked, tap the button at the bottom left
labeled <em>Accept</em>. All the selected dives appear on the <em>Subsurface-mobile</em>
dive list. The downloaded dive information can now be edited as described in
