I have an NRF51822 QFAA C0 (build code)-based hardware for prototyping. But I couldn't find the respective development software, like SDK 4.2.2 and SoftDevice S110 version 5.2.1.
Could you please share with me the link to these files?
I know this chip is a bit old, and I would like to move to the appropriate latest version before finalising the hardware.
Thanks,
Best regards,
Sampath
