Hey everyone
I am trying to stream the cam view of nokia 6600 to pc via bluetooth. I can get the frames from the camera into the buffer but how should i transmit the buffer via bluetooth to pc as data or as obex. And also how will I recieve it at the other end I mean on a windows platform pc. In what language should the recieving application be written so as to get the picture frames. Any suggestions are welcome. Please do respond |

I guess it is not possible to write a symbian c++ application to run on windows platform. So I 've changed my project.
Now I am trying to stream it to another mobile where I can write a symbian c++ application to catch the frames I send and display it on the screen.
But I need to know how to get the bluetooth support for the series 60 sdk platform 2.0 emulator.
If anyone has any idea about the bluetooth support for the emulator please be kind enough to share it with me.
Thanks

Didn't use OBEX, just spat the JPEG from the camera over RFCOMM bluetooth.
Then on the Windows side, a separate app (Win32/MFC) sat monitoring the RFCOMM virtual COM port, and then displayed it in real time.
I then modified it so the Windows side app was changed into a "WebCam" device driver, so apps like Windows messenger saw and could use this virtual web cam.
Was quite neat

Thanks for replying, but it was little late for me to know this.
I was thinking of sending the frames as captured from camera to the pc and there will be problem displaying these frames on a windows platform.
Didn't think of converting them to jpeg and sending. But I think it will be a bit slower since it will also take the extra time for converting.
Anywayz right now I am concentrating on streaming view finder to another mobile.
I hope you can help a lot in this.
To start with, please tell me how shuold I get the bluetooth support for the emulator.
Should I buy a pc bluetooth card or something else.
Please do reply.

Anyway, "real" hardware would be this:
Series 60 1.2 - Nokia DTL-4 card (discontinued)
Series 60 2.0+ - Cassira end point (expensive!!)
There is an alternative though. Get yourself a commerical USB dongle, and either DTL4-X (for S60 1.2) or BH4-X (for everything else). Take a look at the (awful site) http://www.CYBERABI.com/
These drivers essentially enable your USB dongle to emulate the real BT hardware for use with the emulator.

Didster have you really did that???
I mean i'm struggling to do that for some time, and now I'm in the phase of "porting" my windows user mode application to kernel mode driver. But anyway all this time I searched the net for a similar app, and to be frankly the only one that's on the market and comes close is Remote60, but I don't believe that it emulates a real WebCam driver so it doesn't get recognised by messengers (I actually haven't tried Remote60 but I'm pretty sure it doesn't offer this kind of functionality). So how come you did it but didn't even try to sell such a good aplication??? My opinion is you're brugging !!!

But yes, I really did do that. If you want or need proof, feel free to ask for it and ill send you it.
"Porting" to kernel mode isn't a easy task, though I have been writting Windows/DOS/Symbian device drivers on and off for about 8 years, which makes it slightly less daungting.
The reason I never tried to sell it was simply one of support. I developed the driver as an after thought of the application, which in tern was only really done to demonstate a point. And to get it up and running in the shortest time possiable it's a WDM capture driver, as apposed to a VFW one. While this should work on 98+, there are numerous bugs in it when running under 98. It's faultless under XP/2k, but I never had the time to get it stable under 98 - and if you've done much driver development, you'll know 98 is a pig.
There were a few other reasons, it's a bit rough around the edges in places, simply as it was knocked up so quickly.
If a few people are intrested, I will try and find time to tidy it up and flog it. As it stands at the moment, IMHO its good enough to give away for free, but not good enough to sell - manly as it's too tough for the average user to set up.
And no, RemoteS60 does nothing like it. To get it to work like a webcam you need another bit of SW which captures an area of the PCs desktop. You then use that to capture the image which remote S60 is displaying on the screen while having the camera app runnon on the phone. Eligant it's not. Not to mention useless - as the camera goes into sleep mode after a minute or so.

Didster all my respect then. However do you have an email address so we can exchange more opinions on this subject? I'm really interested and have some good ideeas to improve it (like WiFi support for 9500 and data cable connection; perhaps with these 2 mediums much more bandwidth could be obtained).
Best of all

Thanks for the support.
I am using series 60 sdk 2.0 since am working with the 6600. The cyberabi's BH4-X does not work with sdk 2.0. That what it says in its document right here http://host207.ipowerweb.com/~cyberabi/Products/BH4-X/BH4XReadMe.htm
Can I use a bluetooth pc-card for this.

Before i tried to create my own i googled some allready made stuff and found couple shareware programs which could do that kind stuff, but those were more like "not so fancy features, but more candy gui". But what i was searching was something which could be easily usable from other prograns.
So hell yeah, if you have somekind wdm/vfw driver which can read its image from stream or it can update its own screen from file frequently please share it

Can anyone tell me whether nokia 6600 camera plug-in is compatible with series 60 sdk2.1 bcoz sdk2.0 which supports 6600 camera plug-in does not support any bluetooth funtions.

Could you please give me a list of what API should I use to stream frames like you did? and also the steps?
Well, actually I'm thinking of making video phone application in v2.0 above. Is it possible?
Thanx in advance
