I'm just trying to determine if I get full SDK access with the nRF51822-mKIT; or if that requires nRF51822-EK/DK? The current posts on the boards seem to be conflicting in...
Hi Nordic team,
Will the S310 stack be kept, feature- and revision-wise, in lock-step with the S110 stack?
To illustrate my question, can we expect the v7 S110 updates...
