Thanks for the replies on this, I’m only using 2.6 so it was a different issue. Found out the what the problem was last night…POWER! The 2A Samsung Note 4 charger was fine but the cable I was using (not the original Note 4 one) was not! Soon as I swapped over the cable, stable bluetooth PS3 goodness.
I need to rebuild it from scratch tonight as SSH is constantly up and down, which is driving me nuts but I’ve tried so many tweaks to get the pad working, I’ll probably screwed something else.
Thanks again!
