Yes... it does not make sense and hence I made a blanket statement !!
I am using libraries for both the RF24 module and as well for the RFID module and once I create an instance of the required objects then why would I manipulate the Chip select for the individual modules ? Reason why there is no code for it.
Aren't the libraries supposed to release the SPI bus once they are done with it ? Actually what I have seen is that even if I completely comment out all references pertaining to the RFID reader the RF24 still does not work.
It works ONLY when I physically disconnect the RFID reader. So to me this looks like a HW issue ... and I was wanting to know if anyone else had such a problem.
( In a earlier case a similar thing happened with a Chinese SD card reader - it was not releasing the SPI bus and hence did not allow RF24 to work .. I posted the issue and prompt came a response to work around the issue [or] switch over to a SparkFun module. All well after that )
