Obviously no-one will know the specifics of this particular device, but in principle, with the tools that are available under linux at the moment, would it be possible to establish a connection to the device and then send data to it just like an attached serial device? I understand that serial emulation is available under the bluez package, but how far does it go? Can one control individual pins, or is it just as a stream of bytes? My primary idea is to use it inside something like a lamp so that, for example, the brightness can be controlled, or a coffee machine, or anything. And if it is possible, is it also sensible to do it in this way? I understand that bluetooth chips are down to ~$5 (US), but this item is going for ~$170 (US). It there a more cost-effective way of talking to a number of bluetooth devices? Sorry for the long post, and many thanks for any thoughts you might have -Oli ** ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
