Bluetooth Quick Start

The following links will guide you through identifying and resolving common Bluetooth communication problems on your Windows PC. The instructions were written for Windows 7, but other versions of Windows should follow the same general structure. If at any point in time you feel uneasy about performing these steps, Contact us directly and we'll do our best to assist you.

Shearwater Desktop won't be able to connect to your dive computers if it has been paired with Windows beforehand. You can remove the pairing by doing the following...

  1. Go to Start -> Control Panel -> View devices and printers
    BT step 1
  2. A list of your installed devices should show up. You should not see Predator listed as a device.
    • If you see one or more Shearwater Dive Computer devices shown, right-click on each and choose Remove device. Then, retry connecting to your dive computer through Shearwater Desktop.

    BT step 2

Shearwater Desktop can sometimes make an improper Bluetooth pairing which causes frequent disconnects. You can remove the pairing by doing the following...

  1. Go to and type Start -> Type: PC Settings and click the icon with the same name -> PC and devices -> Bluetooth

  2. A list of your installed devices should show up. You should not see Predator listed as a device.
    • If you see one or more Shearwater Dive Computer devices shown, right-click on each and choose Remove device. Then, retry connecting to your dive computer through Shearwater Desktop.

     

Sometimes the wrong Bluetooth driver may have been installed, or there may be more than one Bluetooth radio attached to your PC. You can check this by doing the following...

  1. Ensure the Bluetooth dongle supplied with your dive computer has been plugged in. If it's already plugged in, remove it, wait a few seconds, and plug it back in again.

  2. Go to Start -> Control Panel -> System and Security.
    BT step3
  3. Go to Device Manager (located under the System option).
    BT step4
  4. In the list of items that shows up, you should see a Bluetooth Radios option (it should specifically say Bluetooth Radios, not Bluetooth USB or some other variation). When you expand Bluetooth Radios, you should be seeing two items: the Bluetooth dongle name (may show up as Generic Bluetooth Radio or some other variation) and Microsoft Bluetooth Enumerator.
    • If you see more than these two items, it may mean that you have a built-in Bluetooth radio on your PC. Having more than 1 Bluetooth radio on your PC will cause problems with Shearwater Desktop, so try unplugging the Bluetooth dongle and retry connecting to your dive computer.
    • If you don't see anything listed, it may be that the Bluetooth dongle isn't able to register with your PC. Try unplugging it, rebooting your PC, and plugging it back in again to see if it shows up. Your dive computer will work with most Bluetooth dongles, so if you have another handy you can use it as a replacement. If you don't have one handy, you can Contact Us for a replacement.

    BT step5

Shearwater Desktop is only compatible with the Microsoft Bluetooth stack (the default Bluetooth stack on windows). It isn't compatible with third-party Bluetooth stacks. You can check for third-party Bluetooth stacks doing the following...

  1. Go to Start -> Control Panel -> Programs -> Programs and Features.
    AB step1
  2. Once Programs and Features opens up, it should contain a list of programs installed on your PC. Try looking for items that include the words TOSHIBA Bluetooth, WIDCOMM, CSR Harmony, Bluesoleil, or BlueFritz.
    • If any of these items are installed, they may need to be removed before you can use Shearwater Desktop. Make sure you have all relevant backups before you remove anything. If you're uneasy or unsure about removing something, consult with a professional or Contact Us. In rare cases, you may require the functionality provided by these stacks if you're using other Bluetooth devices with your PC.

 

You may need to reset the pram on your Mac.
Please see this page from Apple support: Resetting the PRAM on your Mac
Unpair all of the Shearwater products from the Bluetooth preferences. You should only need to do this once. Here's how:

  • Mac OS 10.9+: Open Bluetooth Preferences, select the dive computer, and click the grey X to the right of the name of the item. Do this for every Petrel, Predator or NERD that appears in the list.
  • Other Mac OS: Open Bluetooth Preferences, select the dive computer, and press the small minus (-) sign at the bottom of the Bluetooth item list. Do this for every Petrel, Predator or NERD that appears in the list.
In order to address technical requirements, we have changed the format of the firmware upgrade files. You need Shearwater Desktop 2.3.8 or above to update your Shearwater dive computers using this format. You can get it here

The firmware update file was downloaded incorrectly, or a file was chosen that is not a firmware update file. Please try downloading the file from our website again before attempting another firmware update.

We now distribute our firmware inside zip files. The firmware must be extracted from the zip file before being transmitted to the dive computer.
If you are still having trouble, please update your copy of Shearwater Desktop. You can get it here
