SDK 4.2.2 + SoftDevice S110 version 5.2.1

[Sampathg]

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

Hi Sampath,

Please note that the nRF51 is not recomended for new deisgns. And the last SDK with support for it is nRF5 SDK 12.3.0. So if you end up using it (which I woudl strongly recomend against), you should at least migrate to that.

Regardign the question, you can dowload nRF5 SDK version 4.4.2 here (4.2.2 is not available).
