As a first suggestion, put all your Tx and Rx code to one side for the moment.
Have a read of the excellent nRF24L01 tutorial here:
Read the first post to see how the module is wired up.
Then scroll down to post #30 and run the checkconnection sketch on your Tx setup and Rx setup. Post the results of those test here - you can copy and paste the IDE Serial Monitor output (not a screenshot please!) - if you are unsure if the connection check is working correctly.
Then go back to post #2 and try the SimpleTx and SimpleRx sketches.
Report back here how you get on.
