Version 2, October 2017

+

Welcome as a user of Subsurface and Subsurface-mobile, advanced dive logging +software with extensive infrastructure to describe, organize, and interpret scuba and free dives. Subsurface offers many advantages over other similar software solutions, including compatibility with Windows, Mac-OS/X, Linux (many distributions), Android and iOS. In addition, Subsurface is open-source software that allows downloading dive -information from most dive computers.

1. Introducing Subsurface-mobile

-

Subsurface-mobile is an extension of Subsurface which -runs on Android smartphone and tablet devices and is a -tool for viewing or sharing dive information at dive sites where a larger -computer is not useful. Subsurface-mobile for Android also allows -the gathering of GPS locations where dives are performed -(Subsurface-mobile for iOS currently does not support GPS functionality).

-

Subsurface-mobile allows you to enter and save dive information -using a mobile device. Most users of Subsurface-mobile typically use the -mobile app as an extension to the laptop/desktop version of Subsurface. -This allows the storage of dive logs on the Internet sharing them -between the mobile and the desktop versions. But Subsurface-mobile can -be used independently of Subsurface and does not require the use of -cloud storage. -While the desktop version of Subsurface shows much more detailed information +

9. Download dives from a dive computer

+
+

Download of dives is possible from dive computers with a FTDI USB interface, or with a Bluetooth/BTLE interface.

+

First, establish a link between the dive computer and the mobile device.

+

For USB dive computers, USB cables "normally" used +for uploading dives to a desktop/laptop computer do NOT work: these cables often have a full-sized 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 +receptacle of the mobile device. The +OTG cable often has a full-size 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.

+
+
+FIGURE: USB-OTG cable +
+
+

For Bluetooth-equipped dive computers, 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 labled 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. +Each dive has a check-box on the left hand side, used for selecting which dives need 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 labled 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 Edit a dive.

+
+

10. 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.

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). +Afterwards, use the Adroid Back button to return to Subsurface-mobile.

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.
