Hi Boris,
This was some time ago but I have just rewritten the FBSD support in gammu
to be generic BSD support and implemented channel searching using the new
device access (already in FreeBSD) and service discovery (which Max is
working on porting) routines. I wonder if you can validate that my work
doesn't cause any regressions on FreeBSD?
The attached patch adds
cmake/FindBSDBluetooth.cmake
libgammu/device/bluetoth/blue_bsd.c
libgammu/device/bluetoth/blue_bsd.h
and converts the build to use those files instead of the 'fbsd' versions,
which can be removed, and the cmake framework will enable the channel
searching if the new API is present.
I'm not quite ready to commit the bt_dev stuff into NetBSD but will push
this upstream after we have all caught up. I'm not sure if it will be
worth putting the patches into ports or not, will leave that up to you.
