nRF52x Backwards Compatibility With nRF24L+ @250KBPS

[Jay Zebryk]

Hello,

I have an existing customer who has products based upon the nRF24L01+.

He would like to upgrade to the newer nRF52x series but is concerned about backwards compatibility.

What are the ways this could be accomplished without recalling all the nRF24 units for a SW update?

A major consideration is all of existing units are set for 250KBS operation which the newer nRF52 series does not support.

Thanks,

Hi,

In general there is a description on how to setup the nRF5x-series to be backwards compatible with the nRF24L-series in the nRF5 SDK:
http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/esb_users_guide.html?cp=4_0_0_5_1_2#esb_backwards 

However the nRF52-series doesn't support 250kbps mode,  only the nRF51-series can be used for this specific configuration.

Best regards,
Kenneth
