Actually, 5.9.x should work with most BLE devices. It's just that the
Suunto EON Steel in particular wants to see the server side GATT

I don't think the Petrel 2 should have that problem - but I do suspect
you need to have at _least_ Qt-5.8.

And 5.9.1 is preferable, since that does fix a few other annoyances already.
