BlueTooth Phone (No not nokia)
I
have been playing with BrainBoxes cards. The problems revolve really around
what a consumer wants / expects from Bluetooth solutions. It seems most
people
are going for very high level 'ease of use' functionality eg transparent
updating of address books, printing t local printers etc. Had a Nokia 6210
battery pack (pre release) for a while too but it constantly crashed and
had no
real functionality. Facilities at that time involved changing an entry in a
bespoke PC address book application and showing that it als changed in the
mobile phone - little more ! (Psion als have cards available). Now I think
the
Outlook type sync facilities work fairly well.
I
think this is a good consumer approach but for the HA side I wanted much
more
of a lower level (network type) linking of units t allow use of say a web
browser on an iPAQ via a gateway PC. Bluetooth really isn't meant for this,
it
is a wire replacement for consumer type products, based on ad hoc demand
&
plug and play. But no d ubt many derivative benefits will be
exploited.
My
original HA wireless remotes were based around 418/432 Mhz packet based or
serial port emulators - I was using a lot lower bandwidth system based on
character addressed screens - I used Psion handhelds & RadioMetrix RF
products.
I
have found that the coverage area of Bluetooth is als VERY small - In my
house
I have rooms that I cannot even get coverage across - no way between rooms
that
have solid walls. This really has focussed me on 802.11 as my HA solution
rather than BlueTooth. It is vastly superior in speed and coverage area but
obviously more costly. When the volumes are high enough, bringing the cost
down
to enable a BlueTooth receiver in each room then maybe the BlueTooth
approach
will be viable, I must admit it will be nice t have your mobile phone
being
fully integrated as a HA controller / display either in house or on the
road. I
am not sure what access you will have t this level of functionality with
these
phones though. They may well be closed t this sort of application. Being
able
to run a local WAP session over Bluetooth would be the best way through
this. Does anyone know for sure if this will be possible ???? I think
that is the key question here (for HA fans) ?
BTW
-The main reason for the Bluetooth eval was that I am working on a
product for a hobby of mine -a Bridge Scoring system -
http://www.ukusa.demon.co.uk/butler/butler.html
This uses wireless data entry terminals -
currently the packet based 432Mhz devices - BlueTooth however appears to be
a
much better suited technology for this as the cell structure concept and
the
small distances involved match very well with the environment in which the
product is used. Hope this isn't advertising , don't think s as I can't
image
anyone here being interested in such a product
!
PS Lee- The 6310 will I am sure be much less money
than a 6210 + BlueTooth Battery Pak - but I don't how it will compare with
that
Ericsson - which appears to be very attractively priced !! ( I feel a
'Phil'
type impulse buy coming on).
Kevin, with regard t bluetooth,
if
I may ask,what are you using, and what problems are you
having?
I am considering the new
Ericsson
r520,
I think the total price will
come in
under 6210 + pack.
I post the link below for info
only.. I've never bought from/had any contact with these guys, so I
can't
recommend in any way.

Anyone with any bluetooth
hardware
care t give an opinion on the current state of
it?
