Hi,
I use DSlogic for sniffing signals. The device gets connected to the machine by means of USB and comes with support for various platforms, including Mac: d https://www.dreamsourcelab.com/download/
Bought the logic analyzer at AliExpresss for about 60 Eur. And it works really great. It even automatically decodes well-known protocols. Had TX connected to one of the sixteen DSlogic ports and RX to another port of the DSlogic. By applying the logic analyzer to the usage of the original software (for the radio) it really was a piece of cake to figure out the required protocol to be used in order to write a working driver. Did so for the Radioddity R2.
Good luck!

BTW: I think the software for the DSlogic is even opensource (but never investigated on that any further).

- Need a serial port sniffer for mac. I have a USB protocol analyzer
but due to the single-byte polling used, I get a capture buffer line per byte, which is a lot to wade through. I googled but didn't find anything free for OSX. If there's an open source solution let me know, I have built stuff with brew from time to time. ...
