I am working on a project where I have full control on both sending and receiving sides. So in theory I can use any protocol I want as long as both sides agree on it. So I've been using sendNECRaw(), which works fine. But it only sends 32 bits at a time, at least on an Arduino Pro Mini (ATMega328p). If I want to send, say. 48 bits at a time, what is the best approach? Is there an existing protocol to allow me to do that? Thanks.
