Solution found; was able to build and test with the actual device, and works well.
Will send PR in a moment.

Quick followup: I submitted the request for FreeBSD Ports tree inclusion of libsweep; it will take few months (or years? XD) for it to be reflected.

Can you add a branch for FreeBSD to the build system here and try again.
In theory the SDK should work but no one tested it yet.
If you test it and it works feel free to make a pull request enabling compilation on FreeBSD.

Got the build part done.
However, I am getting serial errors: invalid scan response command and invalid response header checksum upon compiling and running examples/example.c.
Controlling actual hardware with sweep-ctl worked well and did not emit any error.
Will dig further and update you with fixes.

It looks like in the middle of the measurement stream, the checksum byte of a data block suddenly being read as \0(0x00), triggering checksum failure. I suspect this being BREAK condition, as in serial.cc the IGNBRK flag has been turned off. But frankly, I don't know why this happens, as I haven't done serial programming before.
For now, I'll keep experimenting with termios flags.
