Replace nRF24

[AndersB]

I have a project where I replaced all wires with wireless communication. And I have one sender and multiple receivers. The wireless communication is constituted by nRF24L01 and the logic of Atmega 328. The distance is within 10m. Datatransfer and amount of data is not critical. I have started the course nRF Connect SDK Fundamentals and find that very interesting.

I would like to replace the nRF24L01 and Atmega 328 with one Nordic chip.

What would you suggest and where can I find examples. As I understand the protocol I am using is the "esb" so I wonder if you would suggest another technology.

As you can se I need some assistance here.

Hi Anders,

Without knowing enough about your product I would assume that most of the nRF52 series devices could replace an nRF24L01 and Atmega 328. You can see the comparison of the different nRF52 devices here. A typical good place to start would be the nRF52832.

nRF Connect SDK also includes support for ESB, so that is an option. It could also be that it would make sense to consider migrating to something like Bluetooth (to get things like encrypted links, frequency hopping, low power, etc) but again, I don't know what suits your product.

For examples you can refer to Enhanced ShockBurst: Transmitter/Receiver. And for Bluetooth, there are samples here and here.

Thank you Einar,

I will start experiment with the examples.
