I inherited an ANT/BLE nRF51422 project a couple of weeks ago.
It used SDK v6.1.0 and S310 SoftDevice v1.0.0
At the time, I'm sure that the SoftDevice download said what version of SDK was required - but I can no longer find that information!
Where is it?
I also downloaded v2 of the SoftDevice at that time (in readiness for an update) - and pretty sure it said SDK 7 required.
But now I see that SDK 8.0.0 is available! Should I use this?
