Keil uVision 5+nRF51822+BLES110 softdevice: should I upgrade my SoftDevice or API?

[riceman0]

Hello, I have inherited a project from a departed employee. I have a requirement (based on a stated desire from her to my project manager) to "bring the SDK and/or SoftDevice up to date" because apparently new versions are available.

We are fairly along in development, so would Nordic (or other developers) recommend I update? What is the latest? Is it backwardly compatible or will I have to make modifications? What are the nifty new features I might want to take advantage of? (Answer by reference perfectly acceptable.) Thanks!

Hi! When you download the .zip file containing the SDK v8.x.x, found here, you will find a releasnote inside. These are the highlights:

• Support for the latest S110, S120, and S130 SoftDevices. (S310 is not supported.)
• SoftDevices included in the SDK.
• Greatly increased driver and HAL coverage.
• New service client and profile example: Current Time Service/Time Profile.
• IAR support for most examples.

If you download the latest SoftDevice v8, found here, you will find releasnotes and documents on how to migrate inside. You should definitely read these documents if you decide to upgrade.
