Hi is it possible using this software to keep plugging in more bluetooth chips/dongles? ie, if i have a hub with 10 dongles in can i utilise them all simultaneously? im looking to do this. Or could I build some custom hardware to do this. Also can this be used in commercial products?
Please clarify your usecase a little. You could have multiple dongles attached (over Serial, USB is not supported by the stack) at the same time and run multiple instances of the stack. If you wanted to have multiple dongles attached to the same instance, that may be doable, but I'd need to understand more of what you're trying to do with it...
Hi Christian, thanks for the response. Well I have set up a system which can send files to people who walk past with their phone (I did this using avetana bluetooth and sending the messages over OBEX). So my system loads, detects the USB bluetooth dongle then constantly detects nearby devices and sends them messages (I have a seperate thread for each device found to avoid holdups). This is not too bad but obviously 1 dongle can only send to 7 simultaneously (if it can even do that in Java???). I would like to be able to add a hub (or whatever) so that I can attach more and more bluetooth chips and my system can handle them so that more messages can be sent simultaneously.
I didnt realise you could even use serial bluetooth devices, but yes as you say I want to be able to either run multiple instances of the stack, or attach multiple dongles to the same instance. Essentially they dont need to even be aware of each other as I will use a DB to store the activity (sent/not sent/failed etc).
I suppose what I want to do is:
- initialise all bluetooth chips attached
- start all bluetooth chips away sending to as many connections as possible (obex)
- update / consult DB
Do you see what I mean? IF its possible to use a small pc and connect many BT chips to it, that could be fine. Otherwise I may look into some sort of hardware which has multiple chips on it, but this seems more hassle etc.
This bluetooth stack seems great, thanks for all your hardwork, I was using Avetana but I think that is based on your work anyway right?
Kind regards,
Gaz.
Hey sorry to bother you, any ideas? :-) This is an experiment into proximity marketing systems.
I was thinking about the brainbox CF cards, would it be feasible to have a USB card reader with lots of these cf cards plugged into it and then i could communicate with each of them using this stack?
