Hi Tabsoft, thanks for comfirming also thanks again for all your help, I wouldnt have got to this point if it wasnt for you. I havent got a simulator so I just test straight on the BB.

I will drop the pause below the osc value, thanks for that tip

Do I implement the nap command in the same way as flashing an LED? So if bittest = 1 : nap 1, if bittest = 0 : goto main? Something like that ?

Thanks again,
Rob
