My Perdix/Perdix AI won't connect to my Windows 7 computer

The latest Shearwater dive computers use a connection technology called Bluetooth LE or Bluetooth Smart. Unfortunately Microsoft has chosen to support this technology only in Windows 8 and later. Perdix AI and some models of Perdix are therefore incompatible with Windows 7. Earlier Shearwater dive computers are unaffected.

However, these dive computers are supported with Shearwater Cloud, available for Android and iOS.

To check your Perdix for Windows 7 compatibility, please do the following:

On your Perdix, go to System Setup->Advanced Config->System Info and check the firmware version.

If your firmware version is in the format vXX/Byy, your Perdix is not supported by Windows 7

If your firmware version is in the format vXX, your Perdix is supported by Windows 7

For example, a Perdix with firmware version v44 is supprted, but a Perdix with firmware version v44/B04  is not.

My Perdix/Perdix AI won't connect to my Windows 8 computer

Shearwater Desktop handles Bluetooth LE pairing, so you normally never need to go to your Bluetooth Settings to set up a Shearwater dive computer.

However, on Windows 8, there is no way to do this pairing inside of a program. This means that you need to pair your Perdix/Perdix AI using Windows 8's Bluetooth Settings page

  1. Go to and type Start -> Type: PC Settings and click the icon with the same name -> PC and devices -> Bluetooth
  2. Put your Perdix into Bluetooth mode by going to Start Bluetooth or Dive Log -> Upload Log depending on your firmware version
  3. Your Perdix should show up in the Bluetooth settings panel on your PC. Click Pair to pair it.
  4. After that, your PC should pair and set up your Perdix.

After that, you should be able to connect to it using Shearwater Desktop.

My Perdix/Perdix AI won't connect to my Windows 10 computer

You should be aware that there is an update to Windows called the Creator's update that is causing significant issues with Bluetooth LE devices like the Perdix. I'd like to rule that out as a possibility.

Please do the following:

  1. Open your start menu and type "winver" and then click on the icon with the same name.
  2. A window with version information about Windows will open up. Please take a look at the number after the work 'Version'

 

If the version is 1703, you have the Windows 10 Creator's Update. If this affects you, unfortunately you will need to wait for another update from Microsoft to address the problem, as this is a Microsoft issue that we don't have control over. Microsoft has mentioned they are working on a fix since late April. So hopefully they push out an update soon to address the Bluetooth Low Energy problems.

In the meantime, you can still try connecting using our App: Shearwater Cloud. It is currently available for iOS and Android and in the future Mac and Windows. So you could use this app if you have not already.

IMPORTANT: It is worth noting that some older Perdix models can connect with “Petrel 1 & 2” selected instead of “Perdix & Perdix AI”, please give this a try if you have an older Perdix.

If you don't have the Creator's Update, then there is a different issue. Please contact us.

 

I get SLIP RX Error on my Dive Computer while doing a Firmware Update with my Mac.

Some of our Dive Computers use a connection technology called Bluetooth Low Energy (BLE). The Firmware of our Dive Computers has a strict timeout if information is not sent to the Dive Computer using BLE fast enough. By Default, some Mac's internal Bluetooth is just a bit too slow and causes the Dive Computer to Time Out. You will need to use the Bluetooth dongle that came with the Perdix which should allow faster communication. Here's how:

  1. Download and run this app, which will configure your Mac to use the USB Bluetooth dongle.
  2. Plug in the dongle that came with your Perdix.

After that you should be able to connect to your Dive Computer with Shearwater Desktop.

If you are still having trouble, please contact us.

My Perdix/Perdix AI won't connect. I have a Mac from 2012 or earlier

Perdix and Perdix AI use a connection technology called Bluetooth LE or Bluetooth Smart. This was introduced in Macs made in 2013 and later. Therefore, earlier Macs do not have this technology, so they are unable to connect as-is. You will need to use the Bluetooth dongle that came with the Perdix. Here's how:

  1. Download and run this app, which will configure your Mac to use the USB Bluetooth dongle.
  2. Plug in the dongle that came with your Perdix.

After that you should be able to connect to your Perdix with Shearwater Desktop.

If you are still having trouble, please contact us.

My Perdix/Perdix AI won't show up in my Mac's Bluetooth Preferences. What gives?

Perdix and Perdix AI use a connection technology called Bluetooth LE or Bluetooth Smart. This is different from Bluetooth (also known as Bluetooth Classic).
Apple has decided not to show Bluetooth LE devices in the Bluetooth Preferences panel on Macs. They also don't show up on iOS devices' Bluetooth Preferences.

Don't worry, neither your Mac nor your Shearwater Dive Computer is malfunctioning.  Shearwater Desktop handles Bluetooth and Bluetooth LE pairing itself, so you normally never need to go to your Bluetooth Preferences to set up a Shearwater dive computer.

You can connect to these dive computers from Shearwater Desktop in the usual way.

I used to be able to connect using my Mac, but now I can't. I've recently upgraded to the latest version of MacOS.

You may need to reset the pram on your Mac.
Please see this page from Apple support: Resetting the PRAM on your Mac

Bluetooth Pairing Conflicts Windows 7 (Predator, Petrel, Petrel 2, Nerd)

Note:  If you have a Perdix or Perdix AI, this does not apply.
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

Bluetooth Pairing Conflicts Windows 8.1 and 10 (Predator, Petrel, Petrel 2, Nerd)

Note:  If you have a Perdix or Perdix AI, this does not apply.
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.

Bluetooth Driver Conflicts

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.
    BTT Usb
  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

Alternate Bluetooth Stacks

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.
