I think that all of the Experimental is all unreliable. I try it 5 days to test it, It always Failure.
So , I want to know that to how to understand the keyword "Experimental".
Since the nRF51 SDK v10.0.0 the 3 Experimental is be add in.
until the 13.0.0.1 alpha the 3 Experimental always be 3 Experimental .
and in 13.0.0.1 the 3 Experimental grow up to 6.
