Perfect thanks again for the reply. Yea I will look around some more as the hope is to send commands via Bluetooth to my Arduino as to control a homemade robot. However I may have just found another solution as I have an old weather station clock that wirelessly receives the time from a separate thermometer placed out side and I am sure that must work with Arduino some home since the wireless modules look very basic and have three clearly marked cables, ground, power and data.
