[Mushtakh Shaikh]

I am having a problem finding the latest versions of SDK and Softdevice compatible with nrf51822?  Please provide me compatible SDK and SoftDevices required to work with nRF51822.

Any kind of help is appreciated.

Hello,

This will depend on what Revision of the nRF51822 SoC that you have.
Please use the this table along with the markings on your IC to identify the revision you are working with.
Then, you may use the SDK and SoftDevice compatibility matrix to find our which SDK and SoftDevice is the latest version compatible with your SoC.

Best regards,
Karl

I look at the information in the above links but then I have this 

https://www.nordicsemi.com/Software-and-tools/Software/nRF5-SDK/Download#infotabs

The link I just pasted says nRF51822 is compatible with SDK 17.0.2 and SoftDevice s140.

From the page3s posted above the information says SDK 12.3.0 and SoftDevice s130 which is what I have done. What's the truth here?
