I know it must be a dumb question so please take it easy on me lol. I’m just starting out and have finally successfully got arduino nano working with nrf24. I was gifted an esp32 and figured I’d try that out just for the heck of it. I noticed it has SS instead of CE as the arduino has. Do they mean the same thing. I know it’s chip enable and slave select but are those two different sets of words for the same function? If not what are the differences. And should I connect the CE Pin of the nrf24 to the SS Pin of the esp32?
CSN is the one that's SS. Some folks say chip select and some folks say slave select. The N is for NOT. That's because it's active LOW. So, like most things on SPI bus, you write it LOW to select that particular chip.
The CE pin does something different.

Oh thanks. That might explain the troubles I’ve been having. So the csn pin is pretty much like saying ssn?
Kind of. Usually they draw a line over it to indicate that it's active low.
There are tons of tutorials online about using that chip. You should be able to find something that walks you through how it gets hooked up.
