How to quickly use nRF54L15 as nRF24L01+based on ESB protocol

[wes187]

I used nRF24L01+ in an industrial control project that requires low power consumption. I have completed all the functional development and reliability verification. A problem that has been discovered now is that the transmission and reception power consumption of 24L01+is relatively high.

I compared nRF54L15 and found that its performance is very powerful and outstanding. I would like to inquire with the manufacturer if there is a firmware that can use nRF52L15 as nRF24L01+? If nRF54 is not available, nRF52 is also acceptable. The power consumption of nRF52 has also been significantly reduced.
I am using the ESB protocol. If none of the above firmware is available, what is the upgrade plan for nRF24L01+? Can be directly compatible. This can help me quickly complete product upgrades. Thank you.

Hi!

Yes, that should be possible.

I suggest getting hold of a nRF54L15-DK , and test out the ESB samples in the nRF Connect SDK to test it.

https://www.nordicsemi.com/Products/Development-software/nRF-Connect-SDK

https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/

From the docs here,

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/esb/index.html , we have:

"Backward compatible with legacy nRF24Lxx Enhanced ShockBurst"

ESB samples in nRF Connect SDK:

Make sure to use the Default legacy radio parameters:

Thanks for your reply:
Zyphyr has a learning cost for me. I am accustomed to the IAR development environment and can perform real-time debugging and monitoring of hardware. Zyphyr is an operating system and there are too many unfamiliar contents. Is there a solution that can directly replace 24L01+?
