In addition, _Subsurface_ is open-source software that allows downloading dive information from many dive computers. Présentation de Subsurface-mobile --------------------------------- _Subsurface-mobile_ est une version mobile limitée de _Subsurface_ 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'est pas utile. Alors que la version de _Subsurface_ pour ordinateur affiche bien plus d'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. _Subsurface-mobile_ permet également de collecter des positions GPS où sont effectuées les plongées. Les utilisateurs de _Subsurface-mobile_ utilisent habituellement l'application mobile en tant que compagnon de la version de _Subsurface_ pour ordinateur, partageant les informations de plongées entre les versions mobile et de bureau. Cependant, _Subsurface-mobile_ peut également être utilisée de façon indépendante de la version de bureau et ne requiert pas l'utilisation du stockage cloud. _Subsurface-mobile_ permet de : - Télécharger et stocker les informations de plongées en utilisant le cloud _Subsurface_. - Visualiser ces informations sur un périphérique nomade. - Créer et ajouter manuellement de nouvelles plongées à votre carnet de plongées. - Télécharger des données de plongées directement depuis plusieurs ordinateurs de plongées. - Modifier de nombreux champs des données de plongées, comme le moniteur, le binôme, l'équipement ou les notes relatives à la plongée. - Enregistrer, stocker et appliquer des positions GPS des plongées. - Visualiser les positions des points GPS enregistrés et des plongées sur une carte. Ces points sont détaillés dans la suite du manuel. _Subsurface-mobile_ 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'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 _Subsurface-mobile_. Sous iOS, seul les ordinateurs de plongées basés sur le Bluetooth LE sont supportés. == Installer _Subsurface-mobile_ sur votre périphérique nomade Vous trouverez _Subsurface-mobile_ dans _Google Play Store_ ou sur _iTunes Store_ d'où vous pourrez les installer. Veuillez boter que les deux contiennent également l'ancienne application '_Subsurface_ companion' (utilisée uniquement pour enregistrer les points GPS). Vérifiez que vous installez bien _Subsurface-mobile_. == Utiliser _Subsurface-mobile_ pour la première fois Lorsque vous exécutez _Subsurface-mobile_ pour la première fois, un écran d'accueil Subsurface est affiché pendant le chargement. Sur certains périphériques, cela peut prendre plusieurs secondes. Après le chargement, l'_écran d'informations de connexion au cloud_ apparait (voir l'image ci-dessous, à gauche). image::mobile-images/Credentials.jpg["FIGURE: Mobile credentials screen", align="center"] === When NOT Using Cloud Storage Tap the "No cloud mode" button. The app will not access the _Subsurface_ 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. === Using Cloud Storage The _Subsurface_ 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 _Subsurface_ on the desktop or _Subsurface-mobile_ using a mobile device; you can do full maintenance of a dive log from _Subsurface-mobile_ alone. By using the same credentials wirh _Subsurface-mobile_ and _Subsurface_ for desktop, the _Subsurface_ cloud storage allows you to share your dive log between both (or even more than two) devices. 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'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. 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) and/or numbers. Tap the "Sign-in or Register" button. If you have already set up an account from the _Subsurface_ desktop application, enter the same credentials here. Once the dive list has been downloaded from the cloud, _Subsurface-mobile_ usually works only with the the local copy on the mobile device. This avoids long delays or even failure of operations if there is a bad (or no) internet connection, a situation fairly common at many dive sites. If this is a new account, a PIN screen will open (see image on right, above). A PIN is e-mailed to the email address entered in the previous step. Enter this PIN into the field indicated and tap the _Register_ button. The user information is stored on the cloud server and access to the cloud is enabled. In this case the dive list is initially empty. Start entering dives in the dive log or download dive information from a supported dive computer. The dive log can be updated automatically. If there is Internet connectivity, _Subsurface-mobile_ 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. === Changing the existing login credentials on the _Subsurface_ cloud The login credentials can be changed, for an example in order to work with multiple accounts. See the section on xref:S_ChangeCloudAccount[Changing to a different _Subsurface_ cloud account]. == Menu Structure and User Interface At the bottom of many Subsurface-mobile screens is a round button that provides for several actions (see image below). The most common choice is indicated in a round colored _action button_ (in the case below, edit a dive). Alternative actions are indicated in a white _action bar_. On Android devices, use the Android Back button for "cancel", "discard" or "back" actions. For example, when editing dive information, tapping the action button saves the changes while the Android back button can be used to cancel the edit without saving changes. On iOS devices, on screens where a "back" action is enabled, a back arrow is shown in the top left corner of the screen. image::mobile-images/Actionbutton.jpg["FIGURE: Action Button", align="center"] In order to have a consistent experience between iOS and Android, _Subsurface-mobile_ on Android does not use the traditional "hamburger" menu button in the top left or right corner of the screen to open menus. Instead, _Subsurface-mobile_ uses a different user interaction philosophy based on the Kirigami framework developed by the Plasma developers. There are three ways to open the main menu: - Tap the "hamburger" symbol in the lower left corner of the screen (easy to reach for hand held devices) - Swipe towards the right across the left edge of the screen - Drag the action button visible on most screens to the right image::mobile-images/Menusystem.jpg["FIGURE: Dive management sub-panel", align="center"] The image above indicates some of the important features of the menu system. On the left is the main menu, activated as described above. On the right of the image are the items of all the submenus accessible. All screenshots in this user manual are currently from the Android version. The iOS screens look fairly similar. == The Dive List Most of the actions of _Subsurface-mobile_ center around the dives on the dive list. While the dive list is loading from the cloud, a message appears at the bottom of the screen, indicating that the cloud is being accessed, after which the dive list is shown. Once the list is loaded you can scroll up and down through your dive history. To upload dives from a dive computer, tap the blue action button. If you wish to add a dive manually, tap the + button in the action bar (described below). Tapping an existing dive on the list brings up a display of _Details View_ for that dive (see image on right below). This includes the dive profile as well as additional information and notes. image::mobile-images/Divelist2.jpg["FIGURE: Dive list screen", align="center"] You can view other dives by swiping the _Details view_ to the right (for the previous dive) or to the left (following dive). Using the Action Bar, it is also possible to delete the dive (tap the dustbin on the Action Bar) or to view the dive location on a map viewer (Google Maps on Android, the Google Maps web site on iOS; tap the GPS icon on the Action Bar.). [[S_Edit_Dive]] == Editing dive details At the bottom of the dive details screen the action button is a pencil (image on right, above). Tapping the pencil button changes the page and enables edit boxes that allow modifying the existing dive information, e.g. adding text to the dive notes or changing the names or values of some of the information (see image below). It may be necessary to scroll the window to access all the information. At the bottom of the edit screen is a _Save_ action button. Tap this to save the new information, after which the dive list screen is updated and shown. To cancel any edits, tap the Android _Back_ Button or the application back button at the top left of the screen on iOS. When the virtual keyboard is shown, to avoid screen clutter, the action button is hidden. Once you close the keyboard it is drawn again. image::mobile-images/Editdive.jpg["FIGURE: Dive edit screen", align="center"] [[S_Add_Dive]] == Manually adding a new dive to the dive list One can manually add a dive to the existing dive list. On the dive list tap the "plus" sign in the action bar, or use the main menu and tap _Manage dives -> Add dive manually_. This opens a screen that is identical to the editing screen discussed above. When a dive is added manually, you cannot directly add a dive profile from a dive computer. However, if you do not use a dive computer, the duration, depth and several other bits of information about the new dive can be entered. The _Action button_ at the bottom of the screen contains a disk symbol. Tap this to save the new dive. To cancel any edits, tap the Android Back Button. The left-hand image below shows a screenshot of a dive being created and the right-hand image shows the same dive in _Details View_. image::mobile-images/Manualdive.jpg["FIGURE: Manual dive entry screen", align="center"] == Deleting a dive The _Details View_ of a dive has an Action Bar, including a dustbin. If this is tapped, the dive shown in the _Details View_ is deleted. You have a brief opportunity to undo the delete by tapping the grey _Undo_ button in the message that appears at the bottom of the screen (see image below). image::mobile-images/Delete_undo.jpg["FIGURE: Undo delete dive", align="center"] You can also delete a dive from the dive list by long-pressing a dive until a red dustbin appears on the right-hand side (see image below). Tap the dustbin. The dive is deleted without asking any confirmation because _Subsurface-mobile_ assumes that the combination of a long tap on the dive with another tap on the red dustbin is an unambiguous instruction to delete the dive. image::mobile-images/RedDustbin.jpg["FIGURE: delete dive from list", align="center"] [[S_Download]] == Download dives from a dive computer 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. 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 _Subsurface-mobile_ is started. On most dive computers this is done through a menu entry, others (like the Suunto models) always respond to BLE requests. 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. 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. Please note that not all Android devices support OTG cables. And even on some devices that do support those cables in general, _Subsurface-mobile_ still in some cases cannot access a dive computer through a serial port. image::mobile-images/USB-OTG.jpg["FIGURE: USB-OTG cable", align="center"] 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 -> Bluetooth tool is probably appropriate. Ensure pairing of the dive computer and mobile device. _Subsurface-mobile_ 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. With pairing between dive computer and _Subsurface-mobile_ having been set up, dive download is simple. From the main menu, tap _Manage dives -> Download from DC_. 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 _Shearwater_ and the Dive computer name is _Petrel 2_. 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). Now tap the button labeled _Download_. 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. 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 _Subsurface-mobile_ 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 _Accept_. All the selected dives appear on the _Subsurface-mobile_ dive list. The downloaded dive information can now be edited as described in the section above xref:S_Edit_Dive[Edit a dive]. image::mobile-images/DC-Download.jpg["FIGURE: DC download screen", align="center"] == Viewing the dive location on Google Maps In the _Details View_, the Action Bar at the bottom has a GPS pin on the left hand side. Tap that pin and the dive site is shown in Google Maps. Close Google Maps by using the Android _Back_ button or tapping on the _Subsurface-mobile_ link in the top left corner on iOS. Alternatively, the _Details View_ has a button at the top right hand marked _Map it_. Tap this button to open Google Maps showing the dive site (image below). image::mobile-images/Map.jpg["FIGURE: Map of dive site", align="center"] == Dive log management A central part of _Subsurface-mobile_ is the ability to store the dive log using the _Subsurface_ cloud storage. This provides security against loss or damage to the dive information in a local copy and allows the desktop version of _Subsurface_ to access changes made using the mobile device. This ability is accessed through the main menu (by dragging the Action Button to the right, or by tapping the "Hamburger" icon at the bottom left of the screen). Tap the option _Dive management_, enabling a number of options: === Add new dive manually This is described above under the section dealing with xref:S_Add_Dive[Manually adding a new dive to the dive list]. === Download from DC This is described above under the section dealing with xref:S_Download[Download dives from a dive computer]. === Apply GPS fixes This is described in the following main section, below. === Manually sync the dive log with the _Subsurface_ cloud storage Upload the dives contained on the mobile device to the _Subsurface_ cloud storage by tapping the option _Manual sync with cloud_. This synchronizes the local changes to the dive log with the cloud storage. It also downloads changes made to the dive log using another device or computer and stored in shared cloud storage. === Enable cloud auto sync By default _Subsurface-mobile_ runs offline and only syncs the dive list with cloud storage when explicitly told to do so (see above). You can choose to always sync with the cloud servers after every modification of the dive list. This is not recommended unless you are in an area with fast and reliable internet connection, as otherwise _Subsurface-mobile_ might appear to hang between operations as it tries to connect to the cloud server. Selecting _Enable cloud auto sync_ causes the local dive log to be synchronized with the copy in the cloud every time that _Subsurface-mobile_ is closed. This option is a switch that allows auto sync to be either activated or to be switched off. == Recording dive locations using GPS The fact that most smartphones have GPS facilities allows _Subsurface-mobile_ to record the locations of dives. If the smartphone is taken on the dive boat during a dive, locations will be automatically recorded at regular intervals. These locations can then be applied to dives in the dive list. Here is how it's done: [[S_ConfigureGPS]] === Configuring the GPS service From the Main menu, select _Settings_. The Settings screen has a section for configuring the GPS service (image below). GPS location data are collected at regular intervals, e.g. every 5 minutes, or at regular distances, e.g. after the boat has moved more than 200m, or a combination of both of these approaches. Provide the appropriate information and tap the _Back_ button. The program is now ready to collect GPS positions. image::mobile-images/GPS-config.jpg["FIGURE: GPS configure", align="center"] === Collecting GPS positions Ensure that the GPS on the mobile device has been activated and that you have given the app permission to access your location data. Open the Main Menu and select _GPS -> Run location service_. This activates the recording of GPS locations. image::mobile-images/GPSstart.jpg["FIGURE: GPS start", align="center"] _Subsurface-mobile_ starts to collect GPS locations automatically, following the preferences specified as described above. While the GPS location service is running, all menus have a GPS symbol at the bottom of the menu, indicating that the service is active. After return from the dive trip, deactivate the collection of GPS data by tapping the option _Disable location service_. The GPS symbol at the bottom of all manus disappears. === Storing the GPS data on the _Subsurface_ cloud Activate the main menu and select the _GPS_ option that brings up the submenu of GPS-related actions. Tap _Upload GPS data_ that saves the GPS data on the _Subsurface_ cloud server. These GPS data are saved *separately* from the other dive log data. All collected GPS data are kept on the Android device, independent of whether they have been uploaded or not. === Downloading GPS data from the _Subsurface_ cloud Download the GPS data that have been saved on the cloud (possibly by a different device) by selecting _Download GPS Data_ from the GPS sub-panel. === Viewing GPS data From the GPS submenu select _Show GPS fixes_. This brings up a list of GPS positions obtained by the location service (image below). Two actions are possible for each of the locations, enabled by dragging the handle (the dotted matrix on the right below) to the left. This exposes two options. Tapping the dustbin deletes this particular GPS location. Tapping the teardrop-shaped icon (actually a Google Maps pin) opens up Google Maps with a pin indicating the exact map position of the GPS record being viewed. The two above options can be hidden by drawing the GPS record to the right, again using the handle. image::mobile-images/gpsmanagement.jpg["FIGURE: GPS management", align="center"] === Applying GPS data to dives in the dive log Assuming that all the dives have been entered into the dive log or have been downloaded from the _Subsurface_ cloud, apply the GPS positions to these dives. GPS positions can therefore only be applied to dives in the dive list. From the _Dive management_ sub-panel, tap _Apply GPS fixes_. The dive list contains the start and end times of each dive. Now, _Subsurface-mobile_ applies the first GPS position that falls within the dive period of each dive. This results in a GPS position for each dive that is saved as part of the dive log. == Utilisation des paramètres pour _Subsurface-mobile_. The Settings screen allows the customization of _Subsurface-mobile_. Many of the settings involve dragging a slider switch to activate or deactivate a particular setting. [[S_ChangeCloudAccount]] === Changing to a different _Subsurface_ cloud account Some users have more than one _Subsurface_ cloud account and with a need to switch between accounts. Tap _Settings_ on the Main menu and scroll to the section titled _Cloud status_ (see image below). Tap the _Change_ button. This opens the _Cloud credentials_ screen. change the credential information, then tap the button _Sign-in or register_. The appropriate dive list is shown. image::mobile-images/SettingsCloudTheme.jpg["FIGURE: Settings: Cloud & Theme", align="center"] === Changing the color theme of _Subsurface-mobile_ _Subsurface-mobile_ has three color schemes to please users with different tastes. This user manual shows the default color scheme, comprising blue colors. Change to a pink or a dark color scheme by opening the main menu, tap _Settings_, and scroll to the section with heading _Theme_ (see image above). Select the appropriate color theme by dragging the appropriate slider on the righthand. === Configuring the GPS webservice The Settings screen allows one to set up the way in which GPS positions are collected during dives. See the section on xref:S_ConfigureGPS[Configuring the GPS service]. === Saving a detailed dive computer dive log Under the heading _Dive computer_, you will find a switch to save a detailed log each time dives are downloaded from a dive computer. This is important for solving problems in downloading dives from the dive computer. When contacting the developers with download problems, you will usually be asked to provide the information in this log, which can be found in the root folder of your local storage device as +libdivecomputer.log+. In the same location you can also find a +subsurfacel.log+ which is always created and which include more information which can be helpful when debugging problems with Subsurface-mobile. === Activating the Developer submenu The information in subsurface.log plus some additional information for understanding the screen rendering of dive information as well as the way in which _Subsurface-mobile_ processed information during a specific occasion while running the app (see section below) is available through a _Developer_ menu at run time. Activate (or deactivate) this menu item on the Main Menu by dragging the slider switch in the Settings screen. == Developer submenu If the Developer submenu has been activated in the Settings screen, the Main menu has a _Developer_ item. By tapping this one has two options that are relevant within the context of program development and debugging. === App log This option shows the messages that _Subsurface-mobile_ generates while running. While most users are not aware of these messages, they are often crucial in detecting any abnormal behavior of the app. The App log can be found in the root directory of the local storage of the mobile device. === Theme information This option provides a wealth of information about the screen characteristics of the mobile device and the font characteristics used by _Subsurface-mobile_.
