How can i connect a digital camera / webcam or digital temp. Sensor ( eg dallas ds series etc. ) directly to a bluetooth or wifi dongle without the need for a pc ? . I have been told the dongle needs a host controller ie a pc but just how much of the pc does it need ? Is it simply a case of a small program to tell the dongle what to do which could be put onto a pic chip or similar ? , any ideas ? , your's , gladys .
