I created a SDP discovery sample and I compiled it with Qt5.5-beta version.
Nothing changed. I still cannot see the SPP service from my HW OSTCs
device when I do a full service discovery.
I also had an attempt to compile the Subsurface project using Qt 5.5.0.
Unfortunately I gave up quickly because I couldn't set correctly the Cmake
paths.

Currently I have firmware 1.80. I saw that there is a new version 1.81
and in the
changeset it says "BUGFIX: Fix download issue for dives made with 1.80
firmware".
I will try to make the update but I am not sure that this will fix the
connectivity
problems. I believe this issue is similar with the one you encountered
on your Petrel
devices.

When I manage to connect to the OSTC 2 device and to initiate the data
transfer I get the same result. It gets stuck somewhere in the middle.
The libdivecomputer back-end initiate a read request for a 1024 buffer
and can read only 923 bytes from device's buffer.
I will let you know if the new firmware fixes this problem.

Of course. I will create a new git branch and I will send you the patches by
the end of this day. First I want to see if something changed after
firmware's update.
