How do I know if nrf24 is working?

Connect one NRF24L01 to Uno R3 and the other to Mega2560. The nRF24L01 module on the UNO constantly sends data, and that on the Mega2560 receives data. Open the IDE and then Serial Monitor for the two boards respectively, and then compare the data sent and received to test whether it succeeds.

What is the difference between NRF24L01 and NRF24L01 +?

Here’s the difference: The NRF24L01+ is a newer version of the NRF24L01, capable of doing an extra 250kbps of on-air data rate while the one without “+” has only 1Mbps and 2Mbps. Both versions can be mixed together as long as 1 or 2 MBps is being used as the data rate.
