I tried some more things on the light controller to see if I could get something to happen, no joy.
However, and I'm gonna be upset if this is the problem, I did realize that I may have got the power output bits muddled, and instead of 0dBm, I might be using -18dBm. I am not 100% sure this means for actual output, but I do know it works out to be around 0.016 of the power, I wouldn't have expected it to be an issue considering the antenna's are about 100mm apart, but you never know. I will turn it up and see what happens. I might look at the differences on the SDR first.
