nRF24L01 inspection

/*
  If your serial output has these values same then Your nrf24l01 module is in working condition :

I moved your topic to an appropriate forum category @princesamsuddin.

In the future, when creating a topic please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Post an annotated schematic showing exactly how you have wired your project. Be sure to show all connections, power sources, grounds, and any other hardware. Explain what the problem is and why the different bit rates between transmit and receive?

Pick one.

It's the same with the CRC length.

OP. Are you using the same nrf24L01 library version and test code on both the transmitter and the receiver?
Supply also a link to the site from which you purchased these modules.
