Is it possible for a Sony Erricson T608 with built-in Bluetooth to act as a
modem and provide Internet access for a Bluetooth enable HP iPAQ 5550 or a
Bluetooth enabled Windows XP Pro laptop?

Using Bluetooth hopefully would be a reliable alternative to a cable between
the phone and iPAQ or laptop.

TIA!!

Yes, quite possible. It's also the only Vision phone supported by Sprint
for use as a modem. $15/mo gets you 3mb transfer.

Ok, well maybe my dream of seeing sigalert.com while driving will be doable!

Has anyone done the connection to Windows or a Windows handheld?

Seems like a dial-up modem driver will be necessary??

I've been using T608 ever since it was released, with iPaq 4350, Nexio
and laptops. No modem driver needed. It is a little tricky to set up
4350, but once it is setup, it is very convenient afterward. When I need
to check email on the iPaq, it dials T608 automatically. I can do email
truly with one hand and 4350's email program is the best I've seen so
far - fast and supports truly multiple accounts. To me, a small BT phone
like T608 beats Treo to death, as you can use any BT devices (PDAs,
laptops, headsets, car BT, etc.).

The only shortcoming of T608 is its short battery life - I have to
charge it every night. Yes the battery is swappable, but swapping
batteries on T608 is a pain in the ass. Anyway, it still beats Treo, as
long as you need more than just a Treo.

I don't understand why people still buying Treo 600. For Sprint, I
understand because there is no BT phones (officially) available. But
for T-Mobile, for example, there is no reason to go Treo while so many
BT phones are available.

BTW, unlike the T610 that has a so so reception, T608's reception is the
best I have seen so far (I have tested Samsung i500, Sanyo 4900, Treo
300, 600 etc.).

I must say, Treo is indeed the best PDA/phone. But if you need more than
that, then BT is the way to go. Generally, BT is much a better
investment as you are not fixed to a single Treo.

In practice, it can be done. It violates the TOS, but it can be done.

Thanks for your reply and the excellent insight from your studied
experience!

I'm thinking of getting the iPAQ 5550. BT will also help avoid the hassle
of an expansion pack for connecting a Sprint wireless PCMCIA card.

To take it a bit further, my Acura TL has BT and now I'm wondering if the
PDA and car can automatically switch sharing the phone so that I can talk on
the phone one minute and get traffic updates the next. Yea, this is all
about trying to avoid going postal on the freeway! :-)

iPaq 5550 has one of the best Bluetooth implementation of any PDA to
date, featuring an audio profile.

Your 'project' would be trying to establish a Bluetooth 'piconet': One
master and up to 7 slaves. Kind-of-proven, especially in the basic
point to point configuration (one master, one basic slave only). In
theory, interconnected piconets form a 'scatternet', an object that
was modelized and simulated in labs quite well, but that only few
lucky ones were able to observe (perhaps a matter of optics size?:) 

Have tried the 5550 running TomTom nav software with BT GPS receiver,
BT phone and BT car kit. No problem getting them all inside the
piconet, with I believe the PDA as the master (initiates BT
connections). GPS signal fed to the PDA navigation over BT, audio nav
from PDA routed to the car speakers through the BT car kit, phone
calls getting through car speakers over BT: All systems are go.

And then something silly happens:

1. Listening to music, with audio guidance from the nav app barging in
once in a while as you should expect, great.
2. Call gets in, mutes the audio. Calling party heard in the car
speakers. All fine.
3. Call terminates... music resumes, but nav audio channel gone
forever.

The GPS data link over BT never was interrupted during the call so the
PDA nav app was still up and running with graphics. Only nav audio
link is lost. PDA connection has to be restarted from tiny
menu-options, not easy while driving...

After some research, seems the car kit can only handle one SCO audio
channel at a time (hardware limitation). 5550 uses the headset profile
when connected to the car kit (that uses one SCO link). Accepting a
phone call pushes out that link, replacing it with its own SCO
(handsfree profile uses one SCO also).

Conclusion: Check hardware limitations on the Accura. Make sure it can
handle 2 SCO audio links and a couple ACL links simultaneously.

Wow, Dan, that was great information and detail! You make it very
interesting.
Lots to think about and experiment with. Thank you!!!

Please share your experiments with all of us, we're at the stage where
beta testers... err, sorry... paying consumers are charting the waters
for more advanced BT networking. Also feeding Bluetooth 1.2
specifications I believe...

Went to check Acura from their website since it's a brand we don't
have around here, and puzzled by a statement that the onboard
multimedia system - including the Bluetooth connectivity - is a
standard outfit on ALL Acura TL models !!?

Up to now, systems this sophisticated with Bluetooth inside were only
offered to geeks as a rather expensive option with other car makers -
I'm thinking of the Toyota Prius, Peugeot 607, or various German
rigs... The so-called Bluetooth option very commonly offered in Europe
on popular models is not factory-fitted, but rather an after-market BT
car kit (black box) that they'd have installed behind the dashboard at
some dealership, just before delivery. Around 300K cars got bluetooth
enabled like that last year. Not too bad considering it carries a $400
to $600 price tag (installed). Most of the time,
people are happy with them, simple enough.

Someone bold at Honda has decided to turn all US Acura owners -
includes you - into BT early-adopters, and there's only a fraction
that many BT-enabled phones in the US as there are in Europe. You drew
a lucky number, and stirred my curiosity...

Query shows the system on the Accura is provided by Johnson Controls
(Also for Chrysler?) and it's part of a full blown onboard computer
with a QNX OS and lots of network interfaces to get the sensors,
steering wheel controls inputs, and to control the various subsystems
(typically through a CAN bus). Nice job.

Now they say voice recognition, noise reduction and echo cancellation
are good. Can you tell us how good is good? Does the voice recognition
work well with open windows? On wet road? Did you have to train it?

Your GPS navigation is built-in, with hard-wired GPS receiver, and
will never require any BT connection. Forget about comments on the
simultaneous audio links at the BT car end, only required for people
who'd want PDA/SmartPhone-based voice-enabled and geolocalisation apps
(someday), to carry out of the car (and I'm a buyer of that, keeps car
simple).

So your car-end Bluetooth is just there to wirelessly host BT phones
with a handsfree profile. Period. No provision for connecting a
terminal using a headset profile, which restricts even further the
choice. A little googling returns the typical flow of customer queries
Acura owners will now be contributing to:

http://www.burningdoor.com/steve/archives/000240.html

To summarize it all: "Well, I have that... BT thing... somehow in my
car, with my phone in the hand, can't ...*pair*... them things
together. Help!". Tech support goes: "Sir, (1) what Bluetooth phone is
it you have again, (2) what firmware version does that phone run on,
(3) what SW version do you have on your handsfree system, and (4) what
is it you're trying to achieve today anyways since there's no two
identical setups/features-sets?". Customer: "???"

Reminder: This is about a simple point to point BT connection between
one master and one slave, using an ad-hoc, off-shelf BT profile. And
there's usually a happy end to it: Customer self-educates and it's
cool enough not to have any phone holder in the way. Eventually,
Johnson Controls will end up sorting it out with phones, firmwares,
and perhaps provide less ambitious phone features. What they have now
seems hard to support across phones / firmwares with some degree of
consistency.

Cellular connectivity for your iPaq would have to go over BT through
your BT phone's antenna, through your cloth fabric, and out of the
car. The problem that was noticed over years' use with this scheme is
that, even in areas with very dense GSM networks such as Europe, you
experience fading signal here and there - compounded by
electromagnetic screening of glass panels which is a trend.

End result of this, there's talk now about re-introducing external
antennas for BT cars (also applies to GPS antennas), and since you
don't want that hodler back, there's that new BT Sim Access Profile
brewing: A behind dashboard cellular module that inherits the
communications functions and account of your phone over Bluetooth. Now
you will need your phone to support that BT Sim Access Profile as well
(new generation), ... and '07 Acuras will have to add yet some little
more electronics.

Yes, lots to experiment with :)
