Using the nRF51822 as an integrated nRF24L01 + Cortex M0

[Liviu]

So far I've been prototyping everything on an Arduino Zero connected to a nRF24. Is switching to an nRF51822 an option for me? or will I have to switch my entire code to work via BLE as opposed to RT?

The nRF24L01 is a pure radio transceiver with a serial interface. The nRF51822 is a system on chip with an embedded Cortex-M0. Both the radio and interfaces have been re-designed, however there is a library for the nRF5 that can be used to communicate through the ESB radio protocol.

A good start is to use the Enhanced ShockBurst User Guide in the latest nRF5 SDK. Currently the latest is nRF5 SDK v11, but you should always check here for updates.
