I am looking into feasability of building a bluetooth-based item that
could be controlled easily from any pc (mostly with linux) for the
purposes of home automation, and I have come upon several bluetooth
dongles with serial ports on them (for example this one:
http://www.socketcom.com/product/CS0400-479.asp), claiming to support
General Access Profile, Service Discovery Profile and Serial Port****
profiles, as well as driverless operation with any serial device
(configuration can be done via AT commands).
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
