MSP430f169 SDK for nRF51422

[ofer]

I have a device the uses MSP430f169 and CC2500 RF controller for communication I need to replace the CC2500 RF controller with nRF51422 device. As I understand an nRF51422 SDK for MSP430 dows not exists. Can I get source of nRF51422 SDK for other device the uses SPI and I will use it to write an SDK for MSP430.

CC2500 is RF controller I can not write any SW to it and the communication now is not BLE. I do not neeed 1:1 replacement I will rewrite all the communication FW on the MSP430 from scratch but for this I need nRF51422 SDK

Let's make it clear what exactly you expect from "SDK". There is indeed nRF51/nRF5 SDK available for free download here but it is primarily meant for hosting entire RF stack and application on nRF5x chip. There are examples of generic wired drivers for SPI/I2C/UART and others and there is "serialization" example/library which allows you to offload some parts of stack/app to extern MCU/host. However it's little bit experimental and as far s I understand it's proprietary, not really in-line with BLE HCI as defined by BT SIG. In the end there is always a question why to do something in MSP when nRF51 has typically more memory and computing power to do everything inside the FW...
