Is CyFi compatible with the CYRF6936?
Using the CyFi solution is only compatible with the CYRF7936, and requires the use of a PSoC device as well as the CyFi Star Network Protocol user module provided in PSoC Designer.
What's the difference between the two devices? I have some existing devices with CYRF6936's already integrated, and I'd really like to avoid duplicating all the work that went into CyFi.
These two devices are used for different pupose. For SNP(Start network protocol) , HUB-Node configuration applications use CYRF7936 and for HID applications like wireless mouse , Keyboard....Use CYRF6936.
CYFI devices are compatible with only CYFI devices.
Exactly you are right. You will be able to include more nodes in a system of CyFi for example if you have network of 10 nodes and a HUB and now you want to include one more node. You will be able to add this node in your design without changing the network. Just designing your node.
