Hi, Has anyone has managed to download dives from a Shearwater Petrel 2 on Linux?
All my attempts have failed in one way or another, and I suspect there might the a difference in the way the Petrel and Petrel 2 communicate. They might look the same, and work the same (except for the compass), but the Petrel 2 is advertised as Bluetooth Smart Ready (aka Bluetooth Low Energy or BLE) and I wonder if this is significant. I posted about this previously, and Anton suggested (http://lists.subsurface-divelog.org/pipermail/subsurface/2015-April/018859.html) trying a different Bluetooth dongles to connect, and using the rfcomm connect (as opposed to bind) command. I went on a bit of a Bluetooth dongle spree. I have tried 4 dongles/devices: 1. The onboard device on my laptop (does not support BLE according to 'hciconfig hci0 features') 2. The one that comes with the Petrel 2 (does not support BLE) 3. A cheap noname Bluetooth 2.0 dongle (does not support BLE) 4. A more expensive Targus Bluetooth 4.0 dongle (does support BLE) All devices will detect the Petrel with 'hcitool -i hci1 scan'. After activating the dongle (sudo hciconfig hci1 up auth), setting the Petrel 2 to upload mode, and using the command 'sudo rfcomm -i hci1 connect /dev/rfcomm 00:13:43:0E:6B:D0', I get the the terminal responses: For all devices except the Petrel 2 supplied dongle: Can't connect RFCOMM socket: Connection refused (the timer on the Petrel screen keeps counting down as if nothing has happened) For the Petrel 2 supplied dongle: Can't connect RFCOMM socket: Invalid exchange (the Petrel displays BT INIT FAIL) I have also tried the libdivecomputer universal tool, built with Jef's experimental native Bluetooth communication (http://trac.libdivecomputer.org/ticket/14). For all dongles, I get: [0.000028] DATETIME 2015-05-16T07:36:55Z (1431761815) [0.000055] VERSION 0.5.0-devel (4094f379aeb25d12fefd6b98d38f79ea6aeea634) [0.000075] Opening the device (Shearwater Petrel, 00:13:43:0E:6B:D0).

I get a slightly different log: [0.000008] DATETIME 2015-05-16T07:08:06Z (1431760086) [0.000496] VERSION 0.5.0-devel (fc7d2ca760c999b8917b2f83681f5c15f233096b) [0.000823] Opening the device (Shearwater Petrel, 00:13:43:0e:6b:d0).

[58.781196] Result: Input/output error On Windows, I can download with Subsurface fine (via COM5 serial connection), and with the Shearwater Desktop application. But I don't like having to boot into Windows. As a side note, I managed to connect to the Petrel 2 using BLE with the Targus dongle and the gatttool command, following a similar method to http://joost.damad.be/2013/08/experiments-with-bluetooth-low-energy.html. Connect works, but I don't know what to do from there. Sorry for the long email, semi-repeating what I wrote previously, but I'd really like to get this working, for me and hopefully help others. Please let me know if there's anything I can do to get to the bottom of this.
