Bluetooth Profiles
(Click here to view the original thread with full colors/images)

Special Thanks to Media Guru for posting this.

Bluetooth has different "profiles" that make up its functionality. There are actually 13 different profiles that go from the obscure to widely used. The GX30/2 actually supports 5 of them:

- Serial-DevB
- GAP
- HandsFree-AG
- Headset-AG
- Serial-DevA

Each profile has to be tested and approved by the Bluetooth Qualification Program. This is supposed to ensure that different Bluetooth devices can interact correctly with each other. You can see what profiles each device has by going to their web site:
http://qualweb.bluetooth.org/Templa...alifiedProducts and doing a search.

There you can see that the GX15 (also known as the GX15##, GX-A15, GX-E15, GX-T15, GX-U15, GZ1, GX-L15, GZ100 !!!) has these profiles supported:

- DUN-GW
- GAP
- OPP-Client
- OPP-Server
- Serial-DevA
- Serial-DevB
- HandsFree-AG
- Headset-AG

The profiles that some of the posters on this forum wish they had on the GX3x are the DUN-GW, Dial-up Networking - this makes the phone act like a modem and the OPP-Client and Server which enable "objects" to be sent and received. Example would be the exchange of electronic calling cards.

One thing to remember with Bluetooth is that profiles have mandatory parts and optional parts, so even though a profile might be supported it might not have everything you want from it. I think this may be the reason for incompatibilities. You'll need to dive into the specs and the PDF documents on the Bluetooth web site to find out what is and is not supported though.

Hope that helps some.

Thanks Synncere.

Excellent, hard-to-come-by information. It could come in very handy for people living outside Belgium...

To be fair, give MediaGuru his props, for posting this, in the GX15 thread.
And thanks Synncere for stickin this at the top.

To put it in english, about why it's important, it's basically the reason, why bluethooth data transfers from the GX30/32 are and will always be impossible, because of a hardware limitation on the phone itself, that, basically means, it is incapable regardless of the software (firmware) used, to send/receive data.

It was a very helpful post, and should in effect, prolly half the amount of post on these boards

It is worth noting that in the original Manual submitted to the regulatory bodies, part of the manual detailed how to connect the phone to a computer on the gx30.

I believe the hardware in the gx30 is capable, a lot of it will or can be handled in software.

It is my earnest belief that the phone would be capable with the right software.

Uh, once again at the risk of sounding stupid (I have effectively 0 programming experience of any sort), what kind of software are we talking about? Firmware for the bluetooth IC's? OS software for the phone as a whole?

No thats the whole point!!!

It's may very well be a hardware limitation, and no software or firmware or anything can make it possible, to send data over the GX30/32 phone.

Bluethooth, has a set of "profiles", and basically, the gx30 bluethooth is only capable of the 5 mentioned in MediaGuru's post. It is possible, that there are parts missing from the gx30, that will not allow it's bluethooth to function in a data send/receive mode.

That's true. However, is it the same story with the Infrared? Are there certain parts missing or something? Or would a firmware solution fix this? It shouldn't be a hardware problem because the IrDA port is able to communicate data with the IrDA-USB cable that connects to the PC.

Now that's true...

I'm going to guess, this has to be a pure software limitation...

I was actually wondering, if it would be possible to just develope a java app for the phone, to send and recieve tru irDa...

Not really, sure, I only ever really worked with basic java, and i'm not even sure, if it could access the hardware, but, i'm just throwing out idea's... The irDa should be capable of transfering data at the least though.

while we're still in the bluetooth question.... i wonder how come my gx32 doesn't connect with other phones via bluetooth? is it a software defect/software problem?
could anybody help me.. help is needed.. thanks y'all

This is what IRKS ME ALOT!!!

I mean, you could've did a simple search, or at the VERY LEAST, read the the first few points of this thread, because, that WAS WHAT THE DISSUCSSION WAS ABOUT!#!?!!

I'll put in very simple words for you.

Alot of people, believe, it was a software issue, however, as MediaGuru was able to point out, it could very well and very likely be, a lack of hardware componets, thus, the phone is incapable of data transfer.

I.E. IT CAN'T CONNECT TO ANOTHER PHONE TO SEND/RECIEVE Data (anything sort of file be it, a photo or ringtone or whatever).

What exactly do you think a Serial connection is?

the phone could certainly transfer data via Serial emulation if it supports Serial DevA and B in hardware, it just needs the software to do it.

I don't know, i'm really out of sorts, when it comes to this.

But i'm going to need to ask you, so we can clarify this whole thing up. Could you explain, what a serial connection is, and why you are certain the GX30 is capable of it?

We need solid information, not guesses.

To connect a bluetooth device to your computer, a new virtual serial port is created, so that the same kind of connections can be established as if the device was actually connected via a serial connection. For example, when I connect my Nokia 6600 to the computer via bluetooth, a new serial port is created (COM6) and the PC suite has to be programmed to connect to the phone on COM6 to send and receive data. In this way, phenylalanine has a point, that it could be possible to connect to the PC, but the software limit prohibits this?
