Is there a way to build with bluetooth support on a mac?

For BLE there is no implementation for any of the supported platforms.

I also mainly use dctool for development and debugging. But for testing the 
actual BLE communication, you'll need a host application like subsurface so you 
can use their BLE implementation.

If you have some capture files, you can also simulate and replay the 
communication. I have a small tool to replay libdivecomputer logs (after some 
postprocessing) over pty's. So if you can easily extract the actual I/O data 
from the capture files, that may also be an option. It's certainly not for 
everything, but it can help to try things without any hardware.

There is also a simulator to simulate the device end of the communication. But 
that's mainly useful afterwards, because it also needs to be implemented of course.
