    How I managed to get a Bluetooth connection working on Linux (POP OS) & Ubuntu

    First things first: make your user is in the dialout group:

    sudo usermod -aG dialout $USER

    Log out or restart for the changes to take effect.

    I had no luck with the subsurface bluetooth interface and had to pair & trust the device manually through bluetoothctl

    bluetoothctl

    If you now put your dive computer in bluetooth mode you should start seeing it advertise itself in the console as shown

    [NEW] Device 00:13:43:##:##:## Petrel
[bluetooth]# [CHG] Device 00:13:43:##:##:## RSSI: 0xffffffc6 (-58) # <-- This is the device we are interested in
[bluetooth]# [CHG] Device 00:13:43:##:##:## RSSI: 0xffffffbe (-66)

    copy the MAC address and enter the following two lines (still in bluetoothctl commandline)

    pair 00:13:43:##:##:##

    You will be prompted to enter a pin (0000).
    You should then see something like the following:

    [bluetooth]# pair 00:13:43:##:##:##
Attempting to pair with 00:13:43:##:##:##
[CHG] Device 00:13:43:##:##:## Connected: yes
[Petrel]# Request PIN code
[Petrel]#   1;39m[agent] Enter PIN code: 0000 <--- enter pin
[Petrel]# [CHG] Device 00:13:43:##:##:## Bonded: yes
[Petrel]# [CHG] Device 00:13:43:##:##:## UUIDs: 00001101-0000-1000-8000-############
[Petrel]# [CHG] Device 00:13:43:##:##:## ServicesResolved: yes
[Petrel]# [CHG] Device 00:13:43:##:##:## Paired: yes
[Petrel]# Pairing successful

    then enter

    trust 00:13:43:##:##:##
    Petrel]# [CHG] Device 00:13:43:##:##:## Trusted: yes
[Petrel]# Changing 00:13:43:##:##:## trust succeeded
[Petrel]# [DEL] Device C8:6C:3D:##:##:## C8-6C-3D-##-##-##
[Petrel]# [CHG] Device 00:13:43:##:##:## ServicesResolved: no

    That’s it, that should be all the command line needed.

    • Open Subsurface import > import from Dive computer or CTRL+D to open the import dialog.
    • Select Shearwater from the manufacturer drop-down
      • Select Petrel (or your own computer model)
    • Click on the ... next to Choose Bluetooth download mode
    • you should see the dialog shown below:
    • Select scan and you should see your device show up with its MAC address & State: AUTHORISED_PAIRED this means our work on the Bluetooth console was successful.
    • Select the computer and in the drop down for Bluetooth mode select Force classic mode (this was required for my old petrel)
    • Click Save
    • You should now see that the device or mount point field is populated with the correct device. And Choose Bluetooth download mode is checked.
    • Click download and new dives should start appearing in the pane on the right.

    After this I was able to import dives normally. One quirk I have noticed is that if I merge two dives (short surfacing in the dive) subsurface will always import all segments again if this is the last dive in the log as it doesn’t seem to recognize that they have already been downloaded.
